One Health Perspectives on Food Safety in Minimally Processed Vegetables and Fruits: From Farm to Fork. Microorganisms 2023; 11:2990. [PMID: 38138132 PMCID: PMC10745503 DOI: 10.3390/microorganisms11122990] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 12/05/2023] [Accepted: 12/08/2023] [Indexed: 12/24/2023] Open
Abstract
While food markets and food production chains are experiencing exponential growth, global attention to food safety is steadily increasing. This is particularly crucial for ready-to-eat products such as fresh-cut salads and fruits, as these items are consumed raw without prior heat treatment, making the presence of pathogenic microorganisms quite frequent. Moreover, many studies on foodborne illnesses associated with these foods often overlook the transmission links from the initial contamination source. The prevention and control of the dissemination of foodborne pathogens should be approached holistically, involving agricultural production, processing, transport, food production, and extending to final consumption, all while adopting a One Health perspective. In this context, our objective is to compile available information on the challenges related to microbiological contamination in minimally handled fruits and vegetables. This includes major reported outbreaks, specific bacterial strains, and associated statistics throughout the production chain. We address the sources of contamination at each stage, along with issues related to food manipulation and disinfection. Additionally, we provide potential solutions to promote a healthier approach to fresh-cut fruits and vegetables. This information will be valuable for both researchers and food producers, particularly those focused on ensuring food safety and quality.

Evaluation of Antibiotics Residues in Milk and Meat Using Different Analytical Methods. Int J Anal Chem 2023; 2023:4380261. [PMID: 37424721 PMCID: PMC10328735 DOI: 10.1155/2023/4380261] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Revised: 06/19/2023] [Accepted: 06/21/2023] [Indexed: 07/11/2023] Open
Abstract
Veterinary drugs are pharmacologically and biologically active chemical agents. At present, veterinary drugs are extensively used to prevent and treat animal diseases, to promote animal growth, and to improve the conversion rate of feed. However, the use of veterinary drugs in food-producing animals may leave residues of the parent compounds and/or their metabolites in food products resulting in harmful effects on humans. To ensure food safety, sensitive and effective analytical methods have been developing rapidly. This review describes sample extraction and cleanup methods, and different analytical techniques are used for the determination of veterinary drug residues in milk and meat. Sample extraction methods, such as solvent extraction, liquid-liquid extraction, and cleanup methods such as dispersive solid-phase extraction and immunoaffinity chromatography, were summarized. Different types of analytical methods such as microbial, immunological, biosensor, thin layer chromatography, high-performance liquid chromatography, and liquid chromatography-tandem mass spectrometry were discussed for the analysis of veterinary drug residues in animal-derived foods. Liquid chromatography-tandem mass spectrometry is the most widely used analytical technique for the determination of antibiotic drug residues. This is due to the powerful separation of LC and accurate identification of MS, and LC-MS/MS is more popular in the analysis of veterinary drug residues.

The Prevalence and Antibiotic-Resistant of Listeria monocytogenes in Livestock and Poultry Meat in China and the EU from 2001 to 2022: A Systematic Review and Meta-Analysis. Foods 2023; 12:foods12040769. [PMID: 36832844 PMCID: PMC9957035 DOI: 10.3390/foods12040769] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 02/04/2023] [Accepted: 02/08/2023] [Indexed: 02/12/2023] Open
Abstract
To compare the prevalence and antibiotic resistance rate of Listeria monocytogenes in livestock and poultry (beef, pork and chicken) meat between China and the European Union (EU), a meta-analysis was conducted. Ninety-one out of 2156 articles in Chinese and English published between January 2001 and February 2022 were selected from four databases. The prevalence of L. monocytogenes in livestock and poultry (beef, pork and chicken) meat in China and Europe was 7.1% (3152/56,511, 95% CI: 5.8-8.6%) and 8.3% (2264/889,309, 95% CI: 5.9-11.0%), respectively. Moreover, a decreasing trend was observed in both regions over time. Regarding antibiotic resistance, for the resistance to 15 antibiotics, the pooled prevalence was 5.8% (95% CI: 3.1-9.1%). In both regions, the highest prevalence was found in oxacillin, ceftriaxone and tetracycline, and a large difference was reported between China and the EU in ceftriaxone (52.6% vs. 17.3%) and cefotaxime (7.0% vs. 0.0%). Based on the above, it remains a significant challenge to enforce good control measures against the meat-sourced L. monocytogenes both in China and in the EU.

Consumers' Preferences for the Traceability Information of Seafood Safety. Foods 2022; 11:foods11121675. [PMID: 35741871 PMCID: PMC9222864 DOI: 10.3390/foods11121675] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Revised: 06/01/2022] [Accepted: 06/05/2022] [Indexed: 12/10/2022] Open
Abstract
Due to importing food and the perpetual changes from conventional wet markets to supermarkets in emerging markets, consumers have the opportunity to base their buying decisions on traceability systems. Seafood traceability systems involve information on production mode, inspection notes, sustainable sources, and sources of origin to provide consumer protection and help ensure that all seafood is safe to consume. This study aims to explore seafood markets by assessing the demand for traceability information attributes by utilising data from an experimental survey in an emerging market such as Bangladesh. The data were analysed using descriptive statistics, exploratory factor analysis, and a conditional logit model. The results demonstrate that consumers are concerned regarding vitamins, cholesterol, and preservatives, while they are little concerned about microbiological contamination, pesticide residues, genetic modification, and additives or artificial colours. The difference between the mean willingness to pay (WTP) for traditional and sustainable farmed fish is higher than that between the mean WTP for conventional and sustainable wild fish. In a ranked-choice voting system, the ‘production mode’ and ‘claim of safety control (e.g., being formalin-free)’ were the first and second most influential attributes in fish choices. The outcomes of the econometric model revealed that consumers are more likely to prefer traceability information about fish control (e.g., formalin-free), and they want to pay a price premium for this information. Alternatively, consumers are less likely to prefer farmed and imported fish, and their WTP for these fishes are highly inflated. This finding may be because consumers use wild and local origin as a cue for food safety or quality. This study hopes that the effects of such traceability information will optimise the production process and supply chain and help make seafood recall management more effective.

Knowledge and Practices of Food Safety among Health Care Professionals and Handlers Working in the Kitchen of a Moroccan University Hospital. J Food Prot 2022; 85:676-685. [PMID: 35051278 DOI: 10.4315/jfp-21-305] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Accepted: 01/14/2022] [Indexed: 11/11/2022]
Abstract
ABSTRACT Food safety plays a key role in the prevention of foodborne illnesses. Mastery of the correct way of handling food is required especially in hospitals where meals are prepared for patients with low immune function. Food safety knowledge among doctors and dieticians is important because of the fundamental role these professionals play in transferring this knowledge to people who need it. The objective of this study was to assess food safety knowledge and practices among health care professionals and food handlers working in the kitchen of a Moroccan university hospital. This cross-sectional study included 72 doctors, dieticians, hygiene technicians, and hospital kitchen employees, who completed a questionnaire to assess their knowledge on hazard analysis critical control point (HACCP) systems, food poisoning, cross-contamination, and food storage and their practices in terms of food safety. Of the participants in this study, 56% said they had received food safety training, and 74% knew the correct definition of HACCP. The overall food safety knowledge mean score was 0.54 ± 0.15, which corresponds to 54% of questions answered correctly. The food safety knowledge areas with the highest mean scores were cross-contamination and food storage, with 0.58 ± 0.20 (58%) and 0.55 ± 0.20 (55%), respectively. The food safety knowledge scores for dieticians and hygiene technicians were higher than those for hospital kitchen workers and doctors. Knowledge about food storage was significantly associated with gender, age, occupation, and level of education (P < 0.05). Correct food practices were observed among 93% of the hospital kitchen staff and 50% of the health care professionals. These results indicate the need for preventive and corrective actions such as training and education about food safety to improve the knowledge and food safety practices of hospital professionals.

Naturally potential antiviral agent polysaccharide from Dendrobium nobile Lindl. PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2020; 167:104598. [PMID: 32527430 DOI: 10.1016/j.pestbp.2020.104598] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Revised: 04/30/2020] [Accepted: 05/05/2020] [Indexed: 06/11/2023]
Abstract
A polysaccharide DNPE6(11) was purified from Dendrobium nobile Lindl. (D. nobile Lindl.). Its structural characteristic, antiviral activity, and preliminary mechanism were studied. The structural characteristic analysis indicated that DNPE6(11) was a novel homogenous heteropolysaccharide from D. nobile Lindl. Bioactivity assays indicated that DNPE6(11) possessed outstanding curative and inactivating activities against cucumber mosaic virus, which were superior to chitosan oligosaccharide and lentinan. Additionally, DNPE6(11) exhibited notable protective activity against potato virus Y, which was better than Ningnanmycin. Furthermore, the preliminary mechanism study found that DNPE6(11) cannot accumulate salicylic acid to induce systemic acquired resistance, but had a strong binding capacity for cucumber mosaic virus coat protein. Therefore, DNPE6(11) could be considered as a promising antiviral agent to study in the future.

Predictive Modeling of Microbial Behavior in Food. Foods 2019; 8:foods8120654. [PMID: 31817788 PMCID: PMC6963536 DOI: 10.3390/foods8120654] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Revised: 12/02/2019] [Accepted: 12/03/2019] [Indexed: 01/23/2023] Open
Abstract
Microorganisms can contaminate food, thus causing food spoilage and health risks when the food is consumed. Foods are not sterile; they have a natural flora and a transient flora reflecting their environment. To ensure food is safe, we must destroy these microorganisms or prevent their growth. Recurring hazards due to lapses in the handling, processing, and distribution of foods cannot be solved by obsolete methods and inadequate proposals. They require positive approach and resolution through the pooling of accumulated knowledge. As the industrial domain evolves rapidly and we are faced with pressures to continually improve both products and processes, a considerable competitive advantage can be gained by the introduction of predictive modeling in the food industry. Research and development capital concerns of the industry have been preserved by investigating the plethora of factors able to react on the final product. The presence of microorganisms in foods is critical for the quality of the food. However, microbial behavior is closely related to the properties of food itself such as water activity, pH, storage conditions, temperature, and relative humidity. The effect of these factors together contributing to permitting growth of microorganisms in foods can be predicted by mathematical modeling issued from quantitative studies on microbial populations. The use of predictive models permits us to evaluate shifts in microbial numbers in foods from harvesting to production, thus having a permanent and objective evaluation of the involving parameters. In this vein, predictive microbiology is the study of the microbial behavior in relation to certain environmental conditions, which assure food quality and safety. Microbial responses are evaluated through developed mathematical models, which must be validated for the specific case. As a result, predictive microbiology modeling is a useful tool to be applied for quantitative risk assessment. Herein, we review the predictive models that have been adapted for improvement of the food industry chain through a built virtual prototype of the final product or a process reflecting real-world conditions. It is then expected that predictive models are, nowadays, a useful and valuable tool in research as well as in industrial food conservation processes.

Abstract
Horse meat and its products can be considered as a food with a high nutritional value. However, due to cases of economically motivated food adulteration by the intentional addition of horse meat beef products in recent years, horse meat has become a controversial issue. Consumer confidence in meat products and the meat industry has diminished, although consumers consider the differences between the food content and the label as the major issue rather than the safety and nutritional characteristics of horse meat. The elaboration of meat products from horse meat (e.g. "cecina", dry-cured loin, salami, bressaola and pâté) is also an interesting alternative to other traditional meat products such as dry-cured pork hams, pork sausages and liver pâtés. In this review, the technological aspects, safety and storage stability of meat products elaborated from horse meat will be addressed by highlighting the nutritional and sensory aspects of these meat products. We aim to improve the existing knowledge about horse meat in the view of recent scandals.
