Global food safety: determinants are Codex standards and WTO's SPS food safety regulations

Toward food safety-driven process design: a systematic review and research agenda

Process design strategies are important to prevent or reduce food safety risks in production systems. In this sense, the Codex Alimentarius presents a set of principles for good hygiene practices to guide food producers. However, studies in food safety often focus on analyzing and controlling implemented production processes without a policy of designing them with a preventive logic, leading to resource misallocation and noncompliance. This study aims to gather and analyze techniques, drivers, challenges, and research opportunities for food safety-driven process design. A systematic literature review was carried out following three steps: (i) Data collection, including 52 studies; (ii) Bibliometric analysis; and (iii) Content analysis, identifying techniques, drivers, challenges, and research opportunities. Three main themes in the subject were identified: process assessment models, risk assessment, and whole-chain traceability. Eleven design techniques were identified and compared according to their typology, structure, and coverage of themes addressed by the Codex Alimentarius. There is a gap in techniques addressing employee competence and personal hygiene. We suggest developing a tool encompassing the Codex Alimentarius good hygiene practices themes in process design to guide food safety-driven process development.

Wild meat trade over the last 45 years in the Peruvian Amazon

The trade in wild meat is an important economic component of rural people's livelihoods, but it has been perceived to be among the main causes of the decline of wildlife species. Recently, the COVID-19 pandemic has brought to light an additional concern of wildlife markets as a major human-health challenge. We analyzed data from the largest longitudinal monitoring (1973-2018) of the most important urban wild-meat markets in Iquitos, Peru, to examine the trends in and impacts of these markets on people's livelihoods. Over the last 45 years, wild meat sales increased at a rate of 6.4 t/year (SD 2.17), paralleling urban population growth. Wild meat sales were highest in 2018 (442 t), contributing US$2.6 million (0.76%) to the regional gross domestic product. Five species of ungulates and rodents accounted for 88.5% of the amount of biomass traded. Vulnerable and Endangered species represented 7.0% and 0.4% of individuals sold, respectively. Despite growth in sales, the contribution of wild meat to overall urban diet was constant: 1-2%/year of total meat consumed. This result was due to greater availability and higher consumption of cheaper meats (e.g., in 2018, poultry was 45.8% cheaper and was the most consumed meat) coupled with the lack of economic incentives to harvest wild meat species in rural areas. Most wild meat was sold salted or smoked, reducing the likelihood of foodborne diseases. Community-based wildlife management plans and the continued trade bans on primates and threatened taxa may avoid biodiversity loss. Considering the recent COVID-19 pandemic, future management plans should include potential viral hosts and regulation and enforcement of hygiene practices in wild-meat markets.

Food supply chain management (FSCM): a structured literature review and future research agenda

Purpose

The main purpose of this paper is to conduct a review of the literature published on food supply chain management (FSCM) in last one and half decade to find out the ongoing research in the field, identify gaps and develop relevant research questions (RQs) from the perspectives of academicians, researchers, policymakers and corporate for the future research.

Design/methodology/approach

In all 281 research articles published on FSCM between the years 2005 and 2020 used for searching online databases such as Emerald, Science Direct (Elsevier), Springer and Wiley online. The methodology of structured review and classification involves various dimensions such as journal, publishing house, country, research design and methods, data analysis tool and multi-criteria decision-making methods.

Findings

It is found that the research in the field of FSCM has gained momentum in the last one and half decades. Majority of published articles are related to food supply chain management and food cold chain. Fewer authors have addressed issues and challenges related to food chain in developing country like India and still fewer studies are found on comparison of present food chain management practices adopted by developing countries like India vis-à-vis developed countries. Also it is observed that limited research is reported in food chain logistics system and intelligent tracking system.

Research limitations/implications

This paper is limited to reviewing only those articles which are related to food chain management.

Originality/value

The main objective of this comprehensive review of literature is to present the various perspectives of food chain management and its numerous challenges. This paper attempts to draw the attention of researchers for further research in the FSCM disciplines. The findings provide future research directions, need of sound policymaking and regulatory mechanism to ensure food security to world's second largest populous country.

Optimization of glutaminase-free L-asparaginase production using mangrove endophytic Lysinibacillus fusiformis B27

Background: The mangrove, Rhizophora mucronata, an essential source of endophytic bacteria, was investigated for its ability to produce glutaminase-free L-asparaginase. The study aimed to obtain glutaminase-free L-asparaginase-producing endophytic bacteria from the mangrove and to optimize enzyme production.

Methods: The screening of L-asparaginase-producing bacteria used modified M9 medium. The potential producer was further analyzed with respect to its species using 16S rRNA gene sequencing. Taguchi experimental design was applied to optimize the enzyme production. Four factors (L-asparagine concentration, pH, temperature, and inoculum concentration) were selected at four levels.

Results: The results indicated that the endophytic bacteria Lysinibacillus fusiformis B27 isolated from R. mucronata was a potential producer of glutaminase-free L-asparaginase. The experiment indicated that pH 6, temperature at 35°C, and inoculum concentration of 1.5% enabled the best production and were essential factors. L-asparagine (2%) was less critical for optimum production.

Conclusions: L. fusiformis B27, isolated from Rhizophora mucronata, can be optimized for L-ASNase enzyme production using optimization factors (L-ASNase, pH, temperature, and inoculum), which can increase L-ASNase enzyme production by approximately three-fold.

A Field Study Into Hong Kong's Wet Markets: Raised Questions Into the Hygienic Maintenance of Meat Contact Surfaces and the Dissemination of Microorganisms Associated With Nosocomial Infections

Millions every day purchase their raw meat in wet markets around the globe, especially in Hong Kong city, where modern and a traditional way of living is made possible. While food hygiene standards in Hong Kong have more recently focused on the safety of meat sold in these wet markets, the hygienic surface level of wooden cutting boards used for processing meats is seldom observed. This original study performed microbial community profiling, as well as isolating and identifying various strains multiple wooden cutting boards from nine wet markets located on Hong Kong Island. Our study also investigated the efficiency of scraping the surface of cutting boards as a traditional cleaning technique in Hong Kong. Results indicate that these hygienic practices are inefficient for guarantying proper surface hygiene as some most tested cutting boards were found to harbor microbial species typically associated with hospital nosocomial infections, such as Klebsiella pneumoniae. Further analysis also led to discovering the presence of antibiotic-resistant genes (ARGs) among isolated strains. Our results showcase the significance and effects of cross-contamination in Hong Kong wet markets, especially with regards to the potential spreading of clinically-relevant strains and ARGs on food processing surfaces. This study should, therefore, serve as a basis to review current hygienic practices in Hong Kong's wet market on a larger scale, thereby improving food safety and ultimately, public health.

Review of the food processing supply chain literature: a UK, India bilateral context

Purpose

The purpose of this paper is to understand the meaning and operationalization of food supply chains in the context of the UK and India.

Design/methodology/approach

The paper follows the systematic literature review approach. The paper examines 99 articles published in peer-reviewed-journals from 1995 to 2017.

Findings

Findings reveal that food supply chain literature is explored along themes of procurement, food processing, innovation, traceability, safety, environment and sustainability, food policy, quality, health, consumer behavior and packaging. Within these themes, the UK researchers have primarily addressed vertical integration, coordination, safety, competitiveness and transparency and information technology. Indian researchers have focused on issues such as consumer perceptions, retail format choice, organic, health and wellness products. An empirical category is the most popular approach. The survey method is the most popular approach followed by the single case studies.

Research limitations/implications

The paper contributes to the body of knowledge by presenting a unified synthesis of articles dealing with the food supply chain in the bilateral context of the UK and India.

Practical implications

The policy makers could use findings for conceptualization of complementarities and possible food supply chain networks.

Social implications

Food processing activities may have potential to provide sustaining livelihoods to around sixty percent of the Indian population which depends on the agriculture. In the bilateral context, the UK may also get a reliable and cost competitive partner to meet its food import needs. This will help the UK to focus more on its service-led economy which, in turn, may create more jobs.

Originality/value

The paper highlights the contextual issues of both the countries and presents opportunities for future collaboration.
