Understanding the Relationships Between the Consumer Perception on Food Risks, Quality, and Safety Indicators of Braised Meat Sold in "Dibiterie" Restaurants in Dakar, Senegal

Dibiteries are restaurants that sell braised meat of small ruminants and sometimes chicken. Current microbiological data indicate that the products sold are sometimes contaminated with pathogenic microorganisms exceeding the quality standards recommended for human consumption, hence a real public health concern. Despite the lack of hygiene, these establishments continue to thrive in the Senegalese food ecosystem. However, very few studies have analyzed the socio-economic motivations and risk representations of these populations who participate in the growing demand for meat from dibiteries. The main objective is to understand the relationships between consumer perception of food risks, quality, and safety indicators of braised meat sold in Dibiteries in Dakar. A total of 479 people from 404 households in the Dakar region were randomly selected and surveyed on the consumption of dibiterie meat using a structured questionnaire. The questionnaire allowed to measure the relative importance given by each interviewee to the indicators related to the risk of food infection, and the quality and safety of dibiterie meat. The structural equation model was used to design the paths and analyze the relationships. Of the 479 people interviewed, 291 people consumed dibiterie meat. Only 16% of consumers strongly perceive the quality and safety of meat. This strong perception has been positively associated with monthly food expenditure, while the age of consumers explained it negatively. Among the latent variables identified, the perceived price effect and the dibiteries' expertise were positively related to the perception on the safety and the perception on the nutritional quality of the product. The nutritional quality of the product had negatively impacted the risks of food infection perceived by consumers. The results of this study suggest the strengthening of hygiene standards in dibiteries and the awareness of consumers, especially young people, about the potential health risks associated with the consumption of dibiterie meat. Further work on willingness to pay to improve the safety of dibiterie meat is needed.

Effect of Dry-Aging on Quality and Palatability Attributes and Flavor-Related Metabolites of Pork Loins

This study evaluated the effect of dry-aging on quality, palatability, and flavor-related compounds of pork loins. Ten pork loins were obtained at 7 days postmortem, divided into three equal portions, randomly assigned into three different aging methods (wet-aging (W), conventional dry-aging (DA), and UV-light dry-aging (UDA)), and aged for 21 days at 2 °C, 70% RH, and 0.8 m/s airflow. The results showed similar instrumental tenderness values across all treatments (p > 0.05), while DA and UDA had a greater water-holding capacity than WA (p < 0.05). Both DA and UDA were observed to have comparable color stability to WA up to 5 days of retail display (p > 0.05). Greater lipid oxidation was measured in both DA and UDA at the end of display compared to WA (p < 0.05). The UV light minimized microorganisms concentration on both surface and lean portions of UDA compared to other treatments (p < 0.05). The consumer panel was not able to differentiate any sensory traits and overall likeness between the treatments (p > 0.05). Metabolomics analysis, however, identified more flavor-related compounds in dry-aged meat. These findings suggested that dry-aging can be used for pork loins for value-seeking consumers, as it has a potential to generate unique dry-aged flavor in meat with no adverse impacts on meat quality and microbiological attributes.

Impact of Purchase Preference, Perceived Value, and Marketing Mix on Purchase Intention and Willingness to Pay for Pork

This study explored the effects of purchase preference, perceived value, and marketing mix on consumers’ purchase intention and willingness to pay for pork in Taiwan. A questionnaire was distributed to pork consumers in an online platform, and a total of 1042 valid samples were collected. An analysis of the questionnaire responses revealed three purchase preference factors, namely flavour, certification marks, and added features; four perceived value factors, namely functional, social, conditional, and emotional value; and four marketing mix factors, namely promotion, convenience, product, and price marketing. Functional value, purchase frequency, conditional value, and product marketing positively affected purchase intention. Promotional marketing, monthly disposable income, and social value were the main positive factors in increased willingness to pay. Consumers who were men, had a lower educational level, purchased large quantities of pork at one time, or frequently purchased pork exhibited higher purchase intention than did other consumers. Those who were men, had higher educational attainment, had a higher monthly disposable income, or held a management position were more willing to purchase pork at a premium price.

The effect of straw based housing on selected quality attributes of pork – a meta-analysis

<b>The aim of the research was to estimate the effect of straw-based housing on selected quality attributes of pork, using a meta-analytical approach. Meta-analysis is statistical procedure that combines the results of individual, independent studies into one common treatment effect, called the effect size. Data were extracted from 17 independent studies (20 experiments) and analysed using a random-effect model to estimate the effect of straw-based housing on the pH (initial pH at 45 min post mortem and ultimate pH), drip loss, colour (L*, a*, b*) and Warner-Bratzler shear force of pork loins. The meta-analysis of the available results showed that pigs from straw-based systems may produce pork with a faster early post-mortem pH decline (pH45), higher drip loss, and greater lightness than those reared under barren conditions with concrete (slatted) floors. A subgroup analysis showed that greater space allowance for straw-housed pigs had a greater negative effect on initial pH (pH45), drip loss, and lightness than straw housing with normal/minimal floor space requirements.

Is there a potential international market for Danish welfare pork? - A consumer survey from Denmark, Sweden, and Germany

This cross-country study investigates the potential to improve pig welfare by exploiting consumer demand, domestically and in export markets, for welfare pork produced in indoor production systems. The analysis is based on questionnaire data collected in 2019 focusing on demand for Danish welfare pork both in Denmark and in two nearby export markets, Sweden and Germany. To reduce hypothetical bias, a willingness-to-pay indicator is combined with an indicator of positive interest in buying a fictive Danish welfare labelled pork. We find that the market potential is relatively weak. Our findings indicate that there is some, albeit limited, potential in Denmark and Germany while demand is practically non-existing in Sweden, probably because the pig welfare guaranteed by Swedish legislation is similar to what is provided by the fictive welfare label employed in the study. Hence, consumer demand alone cannot secure enhanced pig welfare. Moreover, we found national differences in the characteristics of consumers who are interested in Danish welfare pork.

Payments for Conservation of Animal Genetic Resources in Agriculture: One Size Fits All?

Simple Summary

Maintaining minimum population sizes for local livestock breeds is a key goal in the conservation of animal genetic resources. As markets and livestock production systems have tended to favour a narrow base of high-output improved breeds, countries have had to use financial and other incentives to motivate breeders to keep local breeds. This paper explores the potential for more cost-effective alternatives to the most commonly used financial incentive, a fixed payment per animal or livestock unit. We compare the current fixed payment incentives for local breeds under the Slovenian Rural Development Programmme with those instead determined through a competitive tender approach. A stated preference survey was realised to determine the conditions under which breeders would be willing to participate in such an incentive system based on differentiated payments. Willingness to accept (WTA) payment for conservation was found to differ significantly from actual payment levels, being lower for the local sheep and goat breeds, and higher for the local pig breed. This suggests that implementation of differentiated payments would be more cost-effective; particularly when accompanied by measures to streamline administrative requirements, improve access to breeding stock and target support for local breed market valorisation (e.g., promotion of value chains based on designated quality schemes).

Abstract

Local livestock breeds in Slovenia have been eligible for financial incentives in the form of a fixed payment per livestock unit (LU) since 2002. The scheme has however not been successful in reversing the erosion of animal genetic resources (AnGR). This paper investigates an alternative, whereby incentive payments would better reflect breeders’ actual opportunity costs. The paper contributes to the limited existing body of knowledge related to the use of tender mechanisms in the design of the payments for agrobiodiversity conservation schemes (PACS), particularly for AnGR. Empirical findings draw on the results of a stated preference survey involving 301 farmers in Slovenia, engaging, or being potentially able to engage, in the rearing of local pig, sheep and goat breeds. Interval and logistic regression model results suggest that willingness to accept (WTA) conservation support significantly differs from actual payment levels. The estimated WTA was found to be 27% lower for the local sheep and goat breeds and 5% higher for the local pig breed, suggesting that differentiated incentive payments would provide a more cost-effective alternative. Additional analysis of breeders’ preferences and motives for engaging in local livestock breed production further informs understanding regarding AnGR conservation policy and the importance of accompanying actions to reverse negative population trends. These include reducing administrative barriers and enhancing the market valorisation of local breeds.

Panorama and ambiguities of cultured meat: an integrative approach

The purpose of this research was to identify, through a systematic review of the literature, the strengths, weaknesses, threats and opportunities of the production and commercialization of cultured meat, as well as to analyze the challenges to be faced by this new food biotechnology. For this, we analyzed 194 manuscripts published in the Scopus and Web of Science databases that dealt with cultured meat under the perspective of cellular agriculture, employing several nomenclatures. The results indicate that there is still no consensus in the literature about the strengths, weaknesses, threats and opportunities of cultured meat, which constitutes an emerging, multifaceted, and encouraging field of study, and a series of inferences have been made that provide insights into the knowledge analyzed. Finally, we propose an analytical model that combines sub-scenarios from which it becomes possible to understand and anticipate the direction of this new food biotechnology.

Can we associate environmental footprints with production and consumption using Monte Carlo simulation? Case study with pork meat

BACKGROUND

Growing population demands more animal protein products. Pork remains one of the traditional and relatively sustainable types of meats for human consumption. In this paper, life-cycle assessment was performed using data from 12 pig farms. In parallel, a survey on the consumption of pork meat products was conducted analyzing responses from 806 pork meat consumers. The study aims to provide a quantitative calculation of six environmental footprints associated with the consumption of pork meat products in Serbia by analyzing data from pig farms and a pork meat consumption survey.

RESULTS

Results revealed that pork meat production is responsible for the emission of 3.50 kg CO2_e kg^-1 live weight, 16.1 MJ_e kg^-1 , 0.151 mg R11_e kg^-1 , 31.257 g SO_2e kg^-1 , 55.030 g PO_4e kg^-1 and 3.641 kg 1.4 dB_e kg^-1 . Further calculations reveal that weekly emissions of various environmental potentials associated with an average consumer of pork meat products in Serbia are estimated at values of 4.032 kg CO_2e week^-1 , 18.504 MJ_e week^-1 , 0.17435 mg R11_e week^-1 , 35.972 g SO_2e week^-1 and 63.466 g PO_4e week^-1 .

CONCLUSIONS

Results show that, on the one hand, pork products are responsible for environmental production impacts that mainly occur on farms while, on the other hand, consumption is characterized with high meat inclusion rates. As a leverage strategy it is recommended for producers to concentrate on lowering the production impacts rather than trying to reach consumers for sustainability conciseness. © 2020 Society of Chemical Industry.

Moral Convictions and Meat Consumption-A Comparative Study of the Animal Ethics Orientations of Consumers of Pork in Denmark, Germany, and Sweden

BACKGROUND

The relationship between animal ethics orientations and consumer demand for meat with high standards of animal welfare, and the way this relationship plays out in different countries, is not well understood. Using pork as a case study, this comparative study aims to identify the animal ethics orientations that drive purchases of welfare meat in Denmark, Germany, and Sweden.

METHODS

Cross-sectional questionnaire data from representative samples of approximately 1600 consumers in each country were collected. A segmentation of pork consumers (using latent profile analysis) was carried out.

RESULTS

In all three countries, two subgroups were concerned about farm animal welfare: the first subgroup was driven by animal rights values; the second subgroup by animal protection values, where the main principle was that "it is all right to use animals as long as they are treated well". Other consumer groups are less concerned about farm animal welfare and display little or no preference for welfare pork.

CONCLUSIONS

In all three countries, dual demand for welfare pork exists. The findings of this study can be used, among others, to understand the marketability of enhanced welfare animal products and the potential for market-driven animal welfare improvements.

Vitamin D-enhanced pork meat consumers’ purchase intention: an exploratory case study in Spain

Abstract: This paper investigated if Spanish consumers would be willing to consume vitamin D-enhanced pork meat from animals fed on mushrooms treated with ultraviolet (UV) light. The questionnaire briefly explained the context of the study (vitamin D deficiency) and asked the consumers to choose answers with which they were most in agreement (non-enriched meat, enriched meat with synthetic vitamin D or enriched meat with vitamin D from UV-irradiated mushrooms). A survey was conducted to 400 non-vegan nor vegetarian consumers in Aragón (Spain) by direct invitation. Sampling was carried out in a random and stratified manner, by province, gender and age group using the Aragón population data for 2017 (INE). Some sociodemographic, health and consumption habit data were requested. Most consumers preferred non-enriched meat. Treatment with UV-irradiated mushrooms was rejected by most consumers, and the consumers who presented any willingness to buy meat enriched with UV-irradiated mushrooms were in the youngest age group.

Desire to eat and intake of 'insect' containing food is increased by a written passage: The potential role of familiarity in the amelioration of novel food disgust

Over two studies we investigated the effect of various written interventions (passages) on the disgust response towards a food (falafels) which supposedly contained mealworm (insect) flour. Actually, participants (Study 1 N = 80, Study 2 N = 78) were given the same non-mealworm containing food in all conditions. Disgust was measured using: tactile sensitivity, food intake, liking and desire to eat. Results of Study 1 showed that a sustainability passage (sustainability advantages of entomophagy), but not a delicacy passage (oro-sensory qualities of insects), was effective in reducing disgust. In Study 2, contrary to prediction, a passage describing the sustainability and nutritional advantages entomophagy failed to reduce disgust - falafel intake, liking and desire to eat were decreased. However, a passage which described how mealworm flour is produced, did significantly reduce disgust. Taken together, these studies demonstrate that written passages can alter the disgust response, notably resulting in a maintenance of food intake. Interventions that increase the perception of familiarity of a novel food, but not logic-based arguments, may be a key driver of the amelioration of disgust. These results also support the suggestion that altering the ideational component of disgust can result in changes of distaste perception.

Pulses for Healthy and Sustainable Food Systems: The Effect of Origin on Market Price

Pulses are widely acknowledged for their high nutritional value due to high protein content, low content in calories, and low glycemic index; they are a good alternative to animal proteins thus offering a considerable number of social, environmental, and health benefits. Despite pulses being widely acknowledged as healthy and sustainable food, in mainly European countries, consumption is growing but still lower than the recommended level, production is unprofitable in comparison to the current market prices level, and a reduction in harvested area has led to a strong dependence on import for pulses supply. Pulses are particularly fitting to the feature of local food because they can be suitably grown in any context, even in the most complex areas, and consumer interest and awareness of food origin has strongly increased in recent years. Lentils were selected as a case study in this paper that aims to define which features are effective on market price and, in particular, the role of origin declaration on label plays in defining the market price and how the origin attributes may enhance market price and farms competitiveness. The methodological tool for this investigation is the hedonic price model, useful to explain the effects of attributes of pulses affecting the market price. Results contribute to a better understanding of the pulse market, emphasizing that the “origin declaration” on label may have a positive effect on market price.

The Influence of Temperature Differences in Smoking Chamber and Furnace and Smoking Time on the Quality of Medium-Ground Sausages

The aim of the work was to determine the impact of two variants (A and B) of smoking (differing in temperature values, furnace, top and bottom of the smoking chamber and the length of smoking time) in the sausage technological process carried out in a traditional smoking chamber with an indirect furnace. The research material consisted of medium-ground sausages: Country, Home and Bieszczady sausages. The research showed that, as the temperature in the smoking chamber and the smoking time changed, the following texture parameters decreased: cycle hardness 1 and 2, springiness, gumminess and chewiness. In addition, there were shown statistically significant differences (p < 0.05) in the chemical composition of Country sausage between the applied smoking variants. It was also found that the temperature of the furnace, upper and lower smoking chamber and the length of smoking time did not have a statistically significant influence on the share of red (a*) and yellow (b*) in the analysed sausages.

Consumer perceptions of conventional and alternative protein sources: A mixed-methods approach with meal and product framing

Understanding consumer perceptions of meat alternatives is key to facilitating a shift toward more sustainable food consumption. Importantly, these perceptions may vary according to the characteristics of the consumer (e.g., preferences, motivations), the product (e.g., sensory attributes) and the encounter (e.g., how the meat alternative is presented/framed). Qualitative and quantitative methods were applied to examine consumer perceptions of five proposed alternatives to meat: legumes, tofu, seitan, lab-grown meat, and insects. In Study 1, 138 participants provided free associations with regards to conventional animal proteins (e.g., red/white meat, fish) and the five alternatives. Three profiles of consumers were identified: (1) hedonically motivated meat eaters uninterested in meat substitutes; (2) health-oriented meat eaters open to some meat substitutes; and (3) ethically conscious meat avoiders positively oriented to most meat alternatives. In Study 2, the presentation of the product was experimentally manipulated: 285 participants evaluated the same five meat alternatives along several dimensions (e.g., edibility, healthiness), either when framed as an individual product or as part of a larger meal. Overall, most meat alternatives benefited from a meal framing, with the notable exception of legumes, which benefited from an individual framing, and insects which were evaluated quite negatively regardless of framing. The present findings suggest that there is not a single way to frame all meat alternatives that will improve their appeal to all consumers.

Methodology for studying human attitudes and behaviour to cow-calf contact systems

This position paper describes a common stand on methodology of human attitudes and behaviour that is suitable to use in studies regarding cow-calf contact (CCC) in dairy production, in order to create a common knowledge base and foundation for future recommendations of CCC systems. We describe how different quantitative and qualitative methods can be used to study human attitudes to CCC as well as farmer or consumer behaviour. We aim to contribute to a better understanding of the available methods, and hope that this paper can be used as a guideline for future studies in this area.

Product quality information in supply chains: a performance-linked conceptual framework applied to the Australian red meat industry

Purpose

This paper aims to address the association between the quality and quantity of information in supply chains and the costs and benefits of generating, using and sharing it.

Design/methodology/approach

The authors’ conceptual framework draws on multiple disciplines and theories of the value and use of product information. Controllable aspects of information, its quality and quantity, are the focus of the study as drivers of firm and chain performance. Structural equation models of constructs at two stages of the Australian red meat supply chain are employed, using data from a survey of 81 sheep and cattle breeders and commercial producers.

Findings

Information quality influences performance more for some product attributes than others and is more influential than is information quantity. Information sharing for many attributes generates benefits only at high cost. Investment in measurement and transmission technologies is supported for intrinsic and extrinsic measures of quality. Differences in respondents' evaluation of information quality are interpreted as evidence of persistent chain failure.

Originality/value

To the authors' knowledge, this is the first attempt at quantifying and comparing the benefits and costs of information sharing across multiple stages of a supply chain and the first to assess quantitatively the role played by information quality and quantity in generating costs and benefits.

Diet shift: Considering environment, health and food culture

Most studies have suggested that dietary choices have effects on both the environment and human health; however, they have ignored food culture, which is both an "independent variable" and a "dependent variable" of diet choice. The purpose of this study is to explore a diet optimization path that meets nutritional needs and has little impact on the environment, while respecting the local food culture to a large extent. We took China's Xinjiang Uygur autonomous region (hereinafter referred to as "Xinjiang") as the case area because Xinjiang is a multiethnic region with a unique food culture characterized by a high proportion of mutton in meat. According to the study's calculation, the current diet in Xinjiang has a high carbon footprint (CF), water footprint (WF) and ecological footprint (EF) and does not present the nutritional structure of a balanced diet. Considering the trade-offs among environmental carrying capacity, health and food culture is the challenge of changing the local food structure. With the method of multi-objective optimization, we propose "optimal diets", which show potential for mitigating environmental impacts and improving the state of health. Most importantly, one of the optimized diets is most desirable because it considers the preservation of the existing food culture. This study demonstrates the feasibility of providing a route for diet transformation that has double benefits regarding the environment and health, or even triple benefits regarding the environment, health and cultural acceptability.

A social cost-benefit analysis of meat taxation and a fruit and vegetables subsidy for a healthy and sustainable food consumption in the Netherlands

Background

Implementation of food taxes or subsidies may promote healthier and a more sustainable diet in a society. This study estimates the effects of a tax (15% or 30%) on meat and a subsidy (10%) on fruit and vegetables (F&V) consumption in the Netherlands using a social cost-benefit analysis with a 30-year time horizon.

Methods

Calculations with the representative Dutch National Food Consumption Survey (2012–2014) served as the reference. Price elasticities were applied to calculate changes in consumption and consumer surplus. Future food consumption and health effects were estimated using the DYNAMO-HIA model and environmental impacts were estimated using Life Cycle Analysis. The time horizon of all calculations is 30 year. All effects were monetarized and discounted to 2018 euros.

Results

Over 30-years, a 15% or 30% meat tax or 10% F&V subsidy could result in reduced healthcare costs, increased quality of life, and higher productivity levels. Benefits to the environment of a meat tax are an estimated €3400 million or €6300 million in the 15% or 30% scenario respectively, whereas the increased F&V consumption could result in €100 million costs for the environment. While consumers benefit from a subsidy, a consumer surplus of €10,000 million, the tax scenarios demonstrate large experienced costs of respectively €21,000 and €41,000 million. Overall, a 15% or 30% price increase in meat could lead to a net benefit for society between €3100–7400 million or €4100–12,300 million over 30 years respectively. A 10% F&V subsidy could lead to a net benefit to society of €1800–3300 million. Sensitivity analyses did not change the main findings.

Conclusions

The studied meat taxes and F&V subsidy showed net total welfare benefits for the Dutch society over a 30-year time horizon.

The Reformulation of a Beef Patty Enriched with n-3 Fatty Acids and Vitamin D3 Influences Consumers' Response under Different Information Scenarios

The objective of this study was to investigate the sensory acceptability and willingness to pay (WTP) for a beef patty elaborated with beef from a local breed that was enriched with nutritional ingredients (vegetable oil mixture and vitamin D₃). The experiment was conducted under two information scenarios (blind; full: ingredients used to enrich the patties in n-3 PUFA and vitamin D₃). An in-home use test was carried out by 180 consumers to study consumer liking of two low-fat beef patties (C: conventional, M: modified). There were no differences in color and odor for the raw patties (p > 0.05). The sensory parameters of the cooked patties were assessed as being similar (p > 0.05) regardless of the information scenario. The sensory parameters remained crucial criteria for product acceptance and repeat purchase. Consumers positively evaluated the M patty. The information provided to consumers on the composition of the product influenced the response of consumers. It was also observed that the higher the education level of the consumer, the higher their scores for M beef patties in the blind scenario. It is thus necessary to implement appropriate marketing strategies in order to highlight the nutritional properties of the modified patties, making them competitive ahead of conventional patties.

Consumer Understanding of Food Quality, Healthiness, and Environmental Impact: A Cross-National Perspective

The last few decades testify that consumers' concerns for healthier lifestyles and environment care are driving forces for reshaping food buying intentions and their perspectives on food quality. The present study identifies the importance that consumers attach to quality, health, and environment selected cues of purchased food products. More precisely, to elicit preferences for social, environmental, and qualitative food cues, a survey instrument was developed and applied on 797 Belgian and Romanian consumers. Our findings suggest that investigated consumers most frequently use freshness, taste, and appearance to evaluate food quality. The use frequency of food quality cues related to health is primarily influenced by the attention paid to food quality. The most relevant cues of food healthiness are ingredients, nutrition facts, and additives and for food environmental impact are packaging, food origin, and production type. It is concluded that food quality receives high attention both from Belgian and Romanian consumers and health and environment related cues can be used as a means of improving consumer health and environmental protection.

Health-Related Values and Preferences Regarding Meat Consumption: A Mixed-Methods Systematic Review

This article has been corrected. The original version (PDF) is appended to this article as a Supplement.

BACKGROUND

A person's meat consumption is often determined by their values and preferences.

PURPOSE

To identify and evaluate evidence addressing health-related values and preferences regarding meat consumption.

DATA SOURCES

MEDLINE, EMBASE, Web of Science, Centre for Agriculture and Biosciences Abstracts, International System for Agricultural Science and Technology, and Food Science and Technology Abstracts were searched from inception to July 2018 without language restrictions.

STUDY SELECTION

Pairs of reviewers independently screened search results and included quantitative and qualitative studies reporting adults' health-related values and preferences regarding meat consumption.

DATA EXTRACTION

Pairs of reviewers independently extracted data and assessed risk of bias.

DATA SYNTHESIS

Data were synthesized into narrative form, and summaries were tabulated and certainty of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Of 19 172 initial citations, 41 quantitative studies (38 addressed reasons for meat consumption and 5 addressed willingness to reduce meat consumption) and 13 qualitative studies (10 addressed reasons for meat consumption and 4 addressed willingness to reduce meat consumption) were eligible for inclusion. Thirteen studies reported that omnivores enjoy eating meat, 18 reported that these persons consider meat an essential component of a healthy diet, and 7 reported that they believe they lack the skills needed to prepare satisfactory meals without meat. Omnivores are generally unwilling to change their meat consumption. The certainty of evidence was low for both "reasons for meat consumption" and "willingness to reduce meat consumption in the face of undesirable health effects."

LIMITATION

Limited generalizability of findings to lower-income countries, low-certainty evidence for willingness to reduce meat consumption, and limited applicability to specific types of meat (red and processed meat).

CONCLUSION

Low-certainty evidence suggests that omnivores are attached to meat and are unwilling to change this behavior when faced with potentially undesirable health effects.

Plant-Derived Extracts Feed-Addition and Packaging Type Influence Consumer Sensory Perception of Pork

This paper investigates whether the combination of the addition of extracts derived from plants (plants derived extracts, PDE) to pork feedstuff and the meat conservation conditions (packaging and time exposure) affect consumers' perception of pork quality, studied by means of visual appraisal, purchase intention and a home test. The three PDE groups were control, garlic extract and blended oil composed by carvacrol, timol, cynamic aldehide and eugenol extracts. Meat was packed in film, vacuum or modified atmosphere (MAP) packaging. A visual test was designed comprising a four-day storage step followed by a four-day exposure step in a refrigerated island display case. All studied effects influenced visual appraisal scores, being time exposure and packaging effects more noticeable than PDE or pig-sex effects. Meat from MAP scored higher than the rest. Scores decreased as exposure time increased, but this evolution was less perceptible in vacuum packaging and was faster for meat from the garlic group. Only gender affected the visual appraisal scores, with women scoring higher than men. Neither PDE addition nor pig sex affected to purchase intention whereas both exposure time and packaging type did. A maximum of 2 days of exposure would be recommended. In the home-test, meat from male pigs obtained higher scores than meat from female pigs, and none of the consumer-related effects influenced the given scores.

Diet-Related Factors, Physical Activity, and Weight Status in Polish Adults

Obesity is a serious problem for both the individual and society due to its health and economic consequences. Therefore, there is a need to focus on factors which explain this phenomenon and may be useful in preventing future occurrence. The aim of this study was to determine the lifestyle factors coexisting with increased body mass index (BMI ≥ 25 kg/m²) in Polish adults, including factors related to diet (dietary patterns-DPs; dietary restrictions; number of meals; frequency of snacking, eating out, and ordering home delivery meals), physical activity, and sociodemographic characteristics. A cross-sectional quantitative survey was carried out in 2016 amongst 972 Polish adults under the Life Style Study (LSS). To determine the factorscoexisting with BMI ≥ 25 kg/m², the logistic regression model was developed. Women were less likely to be overweight or obese compared to men. The likelihood of BMI ≥ 25 kg/m² increased with age by 4% in each subsequent year of life. Frequent consumption of fruits and vegetables, adhering to restrictions in quantity of food consumed and at least moderate physical activity during leisure time decreased the likelihood of BMI ≥ 25 kg/m². More frequent consumption of meat and eating five or more meals a day increased the likelihood of BMI ≥ 25 kg/m². Diet-related factors explained the developed model better than factors related to physical activity, however, age and gender were the factors most strongly correlated with BMI ≥ 25 kg/m². Therefore, development of strategies to prevent and reduce overweight and obesity should focus on the demographic characteristics of the population, and then on teaching behaviors conducive for reducing the amount of food consumed, especially meat. However, physical activity in leisure time should also be included in the prevention of obesity.

Preliminary investigation into the use of Raman spectroscopy for the verification of Australian grass and grain fed beef

Australian grass and grain-fed beef products attract premium prices at sale and several beef processors market beef underwritten by production system claims. This preliminary investigation assessed the feasibility of using Raman spectroscopy to detect differences in the chemical composition of subcutaneous fat from cattle raised in extensive and intensive production systems. Raman spectra, fatty acid composition, β-carotene composition and objective colour measurements were measured on 150 grass and 150 grain-fed cattle. Spectral differences at peaks including 1069 cm^-1, 1127 cm^-1, 1301 cm^-1 and 1445 cm^-1 suggest that Raman spectra is able to detect differences in saturated fatty acids, which were significantly higher in carcases from grain-fed cattle. Differences in spectra at 1658 cm^-1 were observed, however further research is required to investigate the cause of this spectral feature. Overall, this study indicated that Raman spectroscopy is a potential tool for the authentication of beef carcases from grass and grain-fed production systems.

Predicting the Quality of Meat: Myth or Reality?

This review is aimed at providing an overview of recent advances made in the field of meat quality prediction, particularly in Europe. The different methods used in research labs or by the production sectors for the development of equations and tools based on different types of biological (genomic or phenotypic) or physical (spectroscopy) markers are discussed. Through the various examples, it appears that although biological markers have been identified, quality parameters go through a complex determinism process. This makes the development of generic molecular tests even more difficult. However, in recent years, progress in the development of predictive tools has benefited from technological breakthroughs in genomics, proteomics, and metabolomics. Concerning spectroscopy, the most significant progress was achieved using near-infrared spectroscopy (NIRS) to predict the composition and nutritional value of meats. However, predicting the functional properties of meats using this method-mainly, the sensorial quality-is more difficult. Finally, the example of the MSA (Meat Standards Australia) phenotypic model, which predicts the eating quality of beef based on a combination of upstream and downstream data, is described. Its benefit for the beef industry has been extensively demonstrated in Australia, and its generic performance has already been proven in several countries.

Consumer Response to Mechanically Tenderized Beef (MTB) and MTB Labels: An Exploratory Focus Group Study

In May 2016, labeling of certain nonintact mechanically tenderized beef (MTB) products was mandated in the United States. MTB products should be handled differently by the consumer because pathogens can be transferred from the exterior to the interior of the meat during the tenderization process. Without labeling, it is difficult to visually distinguish between some intact beef and MTB products, which is a concern because MTB products require higher internal cooking temperatures for safety. An exploratory study was conducted to understand consumer understanding of MTB products and consumer responses to the new label. Thirteen focus groups were convened in rural and urban settings across Virginia and North Carolina between December 2015 and May 2016. Sessions were audiorecorded, transcribed verbatim, and analyzed through constant-comparison thematic analysis. Although MTB products were commonly bought, prepared, and consumed, consumer awareness of MTB products and the MTB process was limited. Generally, the label confused participants, and they did not understand the message. Specifically, terminology such as "blade tenderized" and "mechanically tenderized" were preferred over the term "needle tenderized" on labels. Once explained, many individuals wanted more information and better messaging. Through a multiprong approach, other messaging methods (e.g., in stores, through technology, and with certifications) were highly valued by consumers and may result in increased message clarity. Ultimately, the intrinsic and extrinsic properties of the beef rather than the MTB product continued to be the primary guide for purchasing and preparation. This study is the first to be conducted regarding American perceptions of MTB products. An understanding of consumer awareness of MTB products and labels is needed to develop targeted risk messaging communication tools.

Regulatory Focus and the Effect of Nutritional Messages on Health and Well-Being: The Case of Red Meat Intake

BACKGROUND

The persuasiveness of nutritional messages varies according to individual regulatory focus. However, so far research has focused on the negative or positive valence of the message, while we lack research on the differential effectiveness of health vs. well-being messages. We tested whether messages centred on negative health or well-being outcomes influenced the intention to eat red meat, and whether participants' predominant regulatory focus moderated this effect.

METHODS

Participants (N = 207; 83 males, 124 females; mean age = 24.89, SD = 7.76) completed a questionnaire measuring dietary preferences and predominant regulatory focus. They were then presented with different versions of a message describing the negative effects of excessive red meat consumption on either health or well-being. They rated their involvement in the message and intention to eat red meat.

RESULTS

Participants with a prevalent prevention focus showed greater involvement and lower intention to eat red meat after reading health messages than after reading well-being messages. No such difference was found in participants with a prevalent promotion focus.

CONCLUSIONS

Emphasising the avoidance of organic diseases appears to be an effective strategy to involve individuals and reduce their intention to eat red meat, especially when they have a predominant prevention focus.

Effect of sodium chloride and chitosan on the inactivation of heat resistant or Shiga-toxin producing Escherichia coli during grilling of burger patties

Cattle are a reservoir for enterohemorrhagic Escherichia coli (EHEC), and ground beef is a major vehicle for human infection with EHEC. Heat resistance of E. coli, including EHEC, is impacted by NaCl and other additives. This study aimed to evaluate the effect of NaCl and other additives on the heat resistance of E. coli in beef patties. E. coli AW1.7ΔpHR1(pLHR) with the locus of heat resistance (LHR), E. coli AW1.7ΔpHR1(pRK767) without LHR, or a 5-strain cocktail of EHEC were inoculated (10⁷-10⁸ CFU/g) into ground beef (15% fat) with NaCl (0-3%), marinade, carvacrol (0.1%), potassium lactate (3%) or chitosan (0.1%) following different protocols. Patties were grilled immediately, or stored in sterile bags for two days at 4 °C prior to grilling to a core temperature of 71 °C. Cell counts of LHR-positive E. coli AW1.7ΔpHR1(pLHR) were higher than that of the isogenic LHR-negative E. coli AW1.7ΔpHR1(pRK767) by >3 log₁₀ (CFU/g) after cooking. Addition of 3% NaCl increased survival of E. coli AW1.7ΔpHR1(pRK767) and the EHEC cocktail while cell counts of the heat resistant strains were not changed. A protective effect of NaCl was not observed with E. coli AW1.7ΔpHR1(pRK767) or EHEC if cells of E. coli were cooled to 4 °C prior to mixing with cold meat and NaCl, indicating that the response of E. coli to osmotic shock contributes to this effect. Chitosan enhanced the thermal destruction of LHR-positive E. coli AW1.7ΔpHR1(pLHR) in ground beef stored at 4 °C for 2 days, while marinade, carvacrol, or potassium lactate had no such effect, indicating that chitosan can be characterized as an effective hurdle concept to reduce the potential risk of LHR-positive pathogen to meat safety.

Suckler Bulls Slaughtered at 15 Months of Age: Effect of Different Production Systems on the Fatty Acid Profile and Selected Quality Characteristics of Longissimus Thoracis

The objective was to compare the quality of beef from bulls reared in typical Irish indoor systems or in novel grass-based systems. Bulls were assigned to one of the following systems: (a) grass silage plus barley-based concentrate ad libitum (CON); (b) grass silage ad libitum plus 5 kg of concentrate (SC); (c) grazed grass without supplementation (G0); (d) grazed grass plus 0.5 kg of the dietary dry matter intake as concentrate (GC) for (100 days) until slaughter (14.99 months). Carcass characteristics and pH decline were recorded. Longissimus thoracis was collected for analytical and sensory analysis. Lower carcass weight, conformation and fatness scores were found for grazing compared to CON and SC groups. CON bulls had highest intramuscular fat and lighter meat colour compared with grazing bulls. The SC meat (14 days aged) was rated higher for tenderness, texture, flavour and acceptability compared with grazing groups. CON saturated and monounsaturated fatty acid (FA) concentration was highest, conversely, omega-3 FA concentration was higher for GC compared with CON, while no differences were found in polyunsaturated FA. In conclusion, while market fatness specification was not reached by grazed grass treatments, beef eating quality was not detrimentally affected and nutritional quality was improved.

Motivations for Industry Stakeholders in China, Vietnam, Thailand and Malaysia to Improve Livestock Welfare

Simple Summary

Animal welfare is a global issue that is important to civilians in many countries. Despite this, large gaps exist between practices as recommended by a scientific understanding of farm animal welfare; the expectations and understanding of society at large; and the realities within livestock industries across the world. The reasons for this are as numerous as they are challenging to overcome, however, understanding what might motivate key stakeholders to make improvements could form a base from which to begin. The livestock industry are arguably the most important stakeholders with the capacity to make meaningful choices that impact the welfare of animals, yet seldom are they consulted as to why they might make choices that either improve or threaten the welfare of the animals. This study aimed to collect information about the motivations and barriers to improve animal welfare from leaders in the livestock industry. A complex relationship of motivators is uncovered, and the importance of factors such as financial benefit and food safety is discussed. Figures are presented to begin illustrating the relationship between motivators. The findings of this study serve to better understand the motivations of livestock stakeholders in these key Asian nations, and the barriers that may prevent them from making choices that improve the welfare of the animals.

Abstract

Understanding what might motivate livestock stakeholders to improve animal welfare is useful information when developing initiatives that benefit from stakeholder engagement. This study was designed to assess the strength of motivating drivers in the development of attitudes to animal welfare, and the factors that impacted their ability to improve animal welfare. During a series of qualitative focus group sessions with livestock leaders across the same countries (Malaysia, China, Vietnam and Thailand), the current study presented livestock leaders (n = 139) with the most significant results in their country, and collected data pertaining to the meaning and applicability of these results. This data was then subject to thematic analysis to identify salient and repeated motivating factors and meanings. This process revealed a complex picture of relationships between motivators and the contexts that drive them. Figures are presented to begin illustrating these relationships. Some strong motivators were uncovered that were previously rated low in the survey (i.e., financial benefit) or not included at all (e.g., food safety). This paper also presents the opportunity to better understand the strength and relationship of extrinsic and intrinsic motivational forces behind animal welfare improvement.

Meat avoidance: motives, alternative proteins and diet quality in a sample of Swiss consumers

Objective:

Diets lower in meat are considered both highly beneficial for human health and more environmentally friendly. The present study compared consumer groups with different self-declared diet styles regarding meat (vegetarians/vegans, pescatarians, low- and regular meat consumers) in terms of their motives, protein consumption, diet quality and weight status.

Design:

Cross-sectional data from the Swiss Food Panel 2.0 (survey 2017).

Setting:

Switzerland, Europe.

Participants:

Data of 4213 Swiss adults (47·4 % females) from a nationally representative sample living in the German- and French-speaking regions of Switzerland (mean age 55·4 years).

Results:

For vegetarians, vegans and pescatarians, ethical concerns about animal welfare and environmental friendliness, as well as taste preferences are stronger reasons to avoid meat consumption. Female low-meat consumers are more likely to be motivated by weight regulation. Only 18 % of the sample and 26 % of self-declared low-meat consumers met the official dietary recommendations for meat intake. Concerns about animal welfare and taste preferences predicted lower meat intake, whereas perceived difficulty of practising a low-meat diet and weight-loss motives were associated with higher meat consumption in consumers who reported eating little or no meat.

Conclusions:

Our study demonstrates that there can be large discrepancies between consumers’ self-perception and their actual meat consumption. This has to be taken into account when designing public health interventions. Addressing ethical concerns about animal welfare (e.g. through awareness campaigns), further improving the range of vegetarian options and increasing consumers’ knowledge about the dietary recommendations may be ways to promote diets lower in meat.

A social cost-benefit analysis of two One Health interventions to prevent toxoplasmosis

In the Netherlands, toxoplasmosis ranks second in disease burden among foodborne pathogens with an estimated health loss of 1,900 Disability Adjusted Life Years and a cost-of-illness estimated at €45 million annually. Therefore, effective and preferably cost-effective preventive interventions are warranted. Freezing meat intended for raw or undercooked consumption and improving biosecurity in pig farms are promising interventions to prevent Toxoplasma gondii infections in humans. Putting these interventions into practice would expectedly reduce the number of infections; however, the net benefits for society are unknown. Stakeholders bearing the costs for these interventions will not necessary coincide with the ones having the benefits. We performed a Social Cost-Benefit Analysis to evaluate the net value of two potential interventions for the Dutch society. We assessed the costs and benefits of the two interventions and compared them with the current practice of education, especially during pregnancy. A 'minimum scenario' and a 'maximum scenario' was assumed, using input parameters with least benefits to society and input parameters with most benefits to society, respectively. For both interventions, we performed different scenario analyses. The freezing meat intervention was far more effective than the biosecurity intervention. Despite high freezing costs, freezing two meat products: steak tartare and mutton leg yielded net social benefits in both the minimum and maximum scenario, ranging from €10.6 million to €31 million for steak tartare and €0.6 million to €1.5 million for mutton leg. The biosecurity intervention would result in net costs in all scenarios ranging from €1 million to €2.5 million, due to high intervention costs and limited benefits. From a public health perspective (i.e. reducing the burden of toxoplasmosis) and the societal perspective (i.e. a net benefit for the Dutch society) freezing steak tartare and leg of mutton is to be considered.

Generation and distribution of productivity gains in beef cattle farming: Who are the winners and losers between 1980 and 2015?

Surplus accounting is a method for evaluating trends in how a firm's productivity factors (intermediate inputs, capital, land, labour) are performing and how the productivity gains are redistributed between agents in the economy. Here the surplus accounting method was applied on a database of 164 Charolais-area suckler cattle farms running from 1980 to 2015. Over this 36-year period - with differences per sub-period - the cumulative productivity surplus (PS) increased at a low rate of +0.17%/year (i.e. cumulative volume of outputs produced increased slightly more than cumulative volume of inputs used). This timid increase in PS is linked to the constant expansion in labour productivity whereas other factor productivities have shrunk. The observable period-wide macrotrends are that commercial farm businesses struggle to protect their revenues, we also observe a slight fall in input prices, land rent and financing costs, and a huge climb in direct support-policy payments. The bulk of the cumulative economic surplus has been captured downstream - 64% downstream of the cattle value chain as a drop in prices, and 22% downstream of other value chains (chiefly cereals). It emerges that the productivity gains in beef cattle farming mostly benefit the downstream value chain (packers-processors, distributors and consumers), whereas it is mainly government money backing this drop in prices of agricultural output. Here we see the principal of the 1992 'MacSharry' reform at work, with a transfer from the taxpayer through direct support-policy payments through to the consumer via lower prices. The simple fact that farmers' incomes are stagnating is a clear indication that they are net losers in this distribution of productivity gains, despite the improvement in labour factor productivity.

Environmental Effects of the Livestock Industry: The Relationship between Knowledge, Attitudes, and Behavior among Students in Israel

The livestock industry has numerous and diverse impacts on the environment. In a cross-sectional study using an online questionnaire, 361 students were asked about their knowledge, attitudes, and behavior related to the environmental impact caused by livestock industry. The data were analyzed using correlations, t-tests for independent samples, and linear regression models. We found that students have almost no knowledge about the environmental impact of the food they consume, their attitudes are moderately pro-environmental, yet they are not strict about pro-environmental behavior. Students with higher levels of environmental knowledge demonstrated more pro-environmental attitudes and behavior; attitudes mediate the relationship between level of knowledge and behavior with respect to environmental pollution caused by the livestock industry. In addition, participants that rear/reared animals demonstrated more knowledge and pro-environmental attitudes and behavior, and women demonstrated more pro-environmental attitudes and behavior than men. There is a need to raise awareness of the environmental and health impacts caused by livestock industry. An introductory course on environmental science should be integrated into different academic study programs. Further research should be conducted among additional population sectors.

Regional, socioeconomic and behavioural- impacts on consumer acceptability of beef in Northern Ireland, Republic of Ireland and Great Britain

This study was commissioned to assess if there are regional differences in the acceptability of beef between consumers from Northern Ireland (NI), Republic of Ireland (ROI) and Great Britain (GB). Palatability traits were affected by socioeconomic and behavioural factors such as preferred cooking endpoint, animal welfare, value, health aspects of beef product, ease of preparation as well as consumption frequency for specific cuts. "Willingness to pay" (WTP) was influenced by income, preferred cooking endpoint, value of beef product, ease of preparation and consumption frequency for frying steak. Results showed that GB consumers scored higher for the same striploin steak compared to NI and ROI consumers. This may be due to differences in the motivation for beef choice and/or consumption habits. GB consumers were less concerned about the healthiness of beef product and beef origin. In addition, a higher consumption frequency for rump was reported in GB, which may explain the higher sensory scores observed among GB consumers for striploins.
