Abstract
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.

How Livelihood Change Affects Food Choice Behaviors in Low- and Middle-Income Countries: A Scoping Review. Adv Nutr 2024; 15:100203. [PMID: 38462217 PMCID: PMC11007434 DOI: 10.1016/j.advnut.2024.100203] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 01/29/2024] [Accepted: 03/05/2024] [Indexed: 03/12/2024] Open
Abstract
Livelihoods have changed dramatically over the past decade in low- and middle-income countries (LMIC). These shifts are happening in tandem with shifts in individual and household food choice behaviors. This scoping review aimed to identify and characterize mechanisms through which livelihood changes could affect food choice behaviors in LMIC, including behaviors relating to food production, acquisition, preparation, distribution, and consumption. A literature search was conducted using 4 databases: PubMed, PsycInfo, AGRICOLA, and Embase. The search was further enhanced by expert solicitations. Studies were included if they measured or focused on a livelihood change, described or assessed a change in ≥1 food choice behavior, and focused on LMIC. Studies were excluded if they focused on migration from LMIC to a high-income country. Of the 433 articles that were identified, 53 met the inclusion criteria. Five mechanisms of how livelihood change can affect food choice were identified: occupation, locality, time, income, and social relations. Changes in occupation altered the balance of the availability and affordability of foods in local food environments compared with individual food production. Changes in location, time use, and income influenced where food was purchased, what types of foods were acquired, and how or where foods were prepared. Additionally, changes in social relationships and norms led to expanded food preferences, particularly among urban populations. Time limitations and higher discretionary income were associated with consumption of ultraprocessed foods. Understanding the relationships between the changes in livelihood occuring in LMIC and food choices of households in these countries can inform the development of policies, programs, and other actions to promote sustainable healthy diets and planetary health.

Abstract
Traditional pork shops play an essential role in delivering pork, the most popular food in Vietnam, to consumers. Studies have shown the need for investment in training and equipment to improve the safety of pork sold at traditional shops. However, it remains unclear how consumers perceived improvement to the hygiene in pork shops and if they are ready to pay premium prices for safer products. This study used an experimental approach to determine consumers' perception and assessment of improved pork shops and their willingness to pay (WTP) for pork products. A total of 152 respondents in two provinces in Vietnam joined in a Becker–DeGroot–Marschak (BDM) mechanism experiment to collect data on WTP for pork from typical and upgraded pork shops. A questionnaire was used to record consumers' perceptions and assessments of the pork shops and products. Overall, consumers were willing to pay 20% more for upgraded fresh pork than for what is currently available on the market. Consumers trusted in the effectiveness of the upgraded intervention and the quality of pork at the pork shop, which increased their WTP for the upgraded pork. Concerns about contaminated pork had a negative impact on the WTP for typical pork, while the high frequency of pork consumption and the existence of elderly family members led to higher WTP for both products. The findings indicate the potential economic benefit of upgrading pork shops, which would be an important driver to motivate sellers to improve food safety.

How Perspectives on Food Safety of Vendors and Consumers Translate into Food-Choice Behaviors in 6 African and Asian Countries. Curr Dev Nutr 2023; 7:100015. [PMID: 37181131 PMCID: PMC10100931 DOI: 10.1016/j.cdnut.2022.100015] [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: 06/22/2022] [Revised: 10/30/2022] [Accepted: 11/22/2022] [Indexed: 12/24/2022] Open
Abstract
Background Consumption of unsafe foods increases morbidity and mortality and is currently an issue, particularly in low- and middle-income countries. Policy actions to ensure food safety are dominated by mitigation of biological and chemical hazards through supply-side risk management, lessening the degree to which consumer perspectives of food safety are considered. Objectives This study aimed to provide an in-depth understanding, from vendor and consumer perspectives, of how food-safety concerns of consumers translate into their subsequent food-choice behaviors in 6 diverse low- and middle-income countries. Methods Six Drivers of Food Choice projects (2016-2022) provided transcripts from 17 focus group discussions and 343 interviews conducted in Ghana, Guinea, India, Kenya, Tanzania, and Vietnam. Qualitative thematic analysis was used to identify emerging themes important to food safety. Results The analysis suggests that consumers constructed meaning about food safety through personal lived experience and social influences. Community and family members contributed knowledge about food safety. Concerns about food safety were influenced by reputations of and relationships with food vendors. Consumers' mistrust of food vendors was amplified by purposeful adulteration or unsafe selling practices and new methods used to produce food. Moreover, consumers were reassured of food safety by positive relationships with vendors; meals cooked at home; implementation of policies and following regulations; vendor adherence to environmental sanitation and food-hygiene practices; cleanliness of vendors' appearance; and vendors' or producers' agency to use risk mitigation strategies in production, processing, and distribution of food. Conclusions Consumers integrated their meanings, knowledge, and concerns about food safety to achieve assurance about the safety of their foods when making food-choice decisions. The success of food-safety policies hinges on consideration of consumers' food-safety concerns in their design and implementation, alongside actions to reduce risk in food supply.

Abstract
BACKGROUND Healthy and sustainable diets need to be adopted to reduce the negative impact of food consumption on human and planetary health. Food systems account for a third of greenhouse gas emissions. "Dietary Patterns for Health and Sustainability" is a World Health Organization (WHO) project that aims to build consensus among international food, health, and sustainability experts and policymakers on how to conceptualise healthy and sustainable diets and on the actions and policies that could be implemented in the WHO European Region to promote these diets. METHODS A qualitative study among European food, health, and sustainability experts and policymakers to elicit their views on multiple dimensions of food sustainability and health was carried out using a three-phase process, including semi-structured interviews, a Nominal Group Technique, and focus groups during a participatory WHO workshop held in Copenhagen. Thematic analysis was used to analyse the three data sources. RESULTS The workshop resulted in a shared understanding of the interconnected components of sustainable healthy eating habits. As a result of this understanding, a variety of potential solutions were identified, including actions across different policy domains, tools, strategic guidelines, needs, and pathways for sustainable healthy diets. The pathways included the need for a multi-stakeholder approach, as well as the simultaneous execution of an aligned and coherent mix of policies at the local and national levels. CONCLUSIONS The prioritised actions should be aimed at helping government policymakers promote sustainable healthy diets and make decisions on improving dietary patterns for citizens' health and wellbeing in line with the United Nations Sustainable Development Goals in the European Region.

Abstract
Foodborne disease is intimately connected to nutrition and causes considerable harm to health and economic wellbeing. Consumers play a key role in food safety, making it essential to understand the motivations, beliefs, and practices that shape their decisions. Ethnographic research methods are well suited to understanding such topics but have rarely been applied to food safety. This paper presents an evidence synthesis of ethnographic studies, with an emphasis on food safety beliefs, values, and related socio-cultural information, and a focus on consumers' purchasing behaviors. Vendor perspectives are also briefly considered. Key findings include the importance of trust, strategies to reduce risk, the effects of economic status and gender, and broader cultural concepts about foods that influence food purchasing. The synthesis demonstrates that there are numerous social and cultural factors that influence decision making related to food safety, offering insights for the design of interventions to reduce exposure to foodborne disease and improve nutrition.

Abstract
Overweight and obesity continue to increase globally. In England, as in many other countries, this disproportionately affects people who experience socioeconomic deprivation. One factor blamed for inequalities in obesity is unhealthy food provisioning environments (FPEs), leading to a focus on policies and interventions to change FPEs. This paper aims to provide insights into how FPE policies could more effectively tackle inequalities in obesity by addressing a key research gap: how the structural contexts in which people live their lives influence their interaction with their FPEs. It aims to understand how low-income families engage with FPEs through in-depth focused ethnographic research with 60 parents across three locations in England: Great Yarmouth, Stoke-on-Trent, and the London Borough of Lewisham. Analysis was guided by sociological perspectives. FPEs simultaneously push low-income families towards unhealthy products while supporting multiple other family needs, such as social wellbeing. FPE policies and interventions to address obesity must acknowledge this challenge and consider not just the makeup of FPEs themselves but how various structural contexts shape how people come to use them.

Abstract
Objectives Vietnam’s post-war globalization, economic development, and urbanization have contributed to a nutrition transition from traditional diets to highly-processed diets, and increased prevalence of childhood overweight and obesity. Our study aims to explore the attitudes and behaviors driving this epidemic. Methods This qualitative study focused on the perspectives and practices of Vietnamese parents, schoolteachers and doctors. Semi-structured interviews were conducted with a convenience sample of 12 regarding the historical, social, and cultural influences contributing to childhood overweight and obesity. Audio-recorded interviews were translated and transcribed, then analyzed using modified ground theory to identify themes and representative quotes. Results Five themes were identified: (1) Change in diet between generations, (2) Preference for rounder children, (3) Unhealthy feeding practices, (4) Reduced physical activity, and (5) Increasing awareness of childhood obesity. A conceptual map detailed the shift from war-time to post-war economic environment and psycho-social context for raising children to be large, safe and academically-successful. Conclusions for Practice We found that globalization, urbanization and economic development—in the context of historical, social and cultural attitudes—may contribute to increasing child obesity in Vietnam. Obesity prevention through public health and educational institutions should involve policies and programs for healthy eating and exercise, tailored to address parental figures’ concerns.

Abstract
The values associated with food are framed and constructed by market-based systems that assign attributes to different foods across the marketplace. The aim of the paper was to conceptualize the range of non-financial aspects associated with food in the literature examined and a typology was introduced to position a new set of non-financial food values, the alter-values, which support the creation of a more holistic approach to visualize and reimagine a more sustainable, resilient food system that readdresses and respects such values. The four alter-values of interest, intrinsic, production-related, supply chain related, and emotio-cultural values, were discussed in the context of changing food environments, and a visualization of the typology was presented to explain them. By focusing especially on intrinsic and emotio-cultural values, an adaptation of the current food environment beyond pecuniary-based emphasis was possible. Such an approach helps to challenge the structure of the conventional food system towards a more citizen-driven sustainable model, altering priorities, with a drive towards embedding values and going beyond perceiving food only in terms of exchange value, to considering food as a vital aspect of life.

Abstract
This paper uses detailed data from in-depth interviews with consumers (n = 47) and vendors (n = 37) in three traditional markets in Birnin Kebbi, Nigeria. We used observations from those markets to examine how consumers and vendors identify and avoid or manage food safety risks and whom they hold responsible and trust when it comes to ensuring food safety. At the level of the vendor, consumers mentioned seeking "clean" or "neat" vendors or stalls. Cleanliness was primarily related to the appearance of the vendor, stall, and surroundings; reliance on trusted, known vendors was also noted. Food products themselves were largely evaluated based on visual cues: insects, holes, and colors-with some reliance on smell, also. Similarly, vendors assessed safety of food from suppliers based on a visual assessment or reliance on trusted relationships. On the second research question, both consumers and vendors largely placed responsibility for ensuring food safety on government; when asked specifically, consumers also named specific steps that vendors could take to ensure food safety. Consumers and vendors also generally felt that they could limit many food safety risks through identifying the "good" products in the market or from suppliers. The paper discusses the implications of these results for behavior change interventions.

Abstract
PURPOSE OF REVIEW This paper aimed to summarise existing literature on strategies to improve the healthiness of retail food environments in the East Asia and Pacific (EAP) region, and propose a prioritised research agenda on this topic. RECENT FINDINGS Little research on retail food environments has been conducted in the EAP region. Several approaches for measuring retail food environments were identified, although none have been tailored to the EAP context. A small number of policies and initiatives to promote healthy retail food environments have been implemented in EAP. Lessons learnt from successful implementation of initiatives in other regions could be applied in EAP. Retail food environments have a strong influence on food choices and health outcomes. Research can contribute to efforts to improve the healthiness of retail food environments in EAP by (1) describing the current state of retail food environments to highlight areas of good practice and concern and (2) identifying policies and initiatives that are likely to be effective, and mechanisms for their successful implementation.

Abstract
Globalization is transforming food environments in low- and middle-income countries (LMICs) with implications for diets and nutrition. However, most food-environment assessments were developed for use in high-income countries. We evaluated the suitability of 113 data-collection assessments (i.e., methods, tools, and metrics) for eight dimensions of informal and formal market food environments for diverse contexts of LMICs. We used a scoring exercise and a survey of experts (n = 27). According to the scoring exercise, 10 assessments (8 methods, 1 tool, and 1 metric) were suitable without modification for informal markets. Suitability for formal markets was markedly higher, with 41 assessments (21 methods, 14 tools, and 6 metrics) found suitable without modification. Experts considered availability, accessibility, price, and affordability the most important dimensions of market food environments to evaluate in LMICs. Market-basket analysis and vendor audits (which include inventories) were ranked as the most suitable methods to assess multiple dimensions of market food environments, including availability, price, affordability, vendor and product characteristics, marketing, and regulation. Gaps in relevant assessments were found for convenience and desirability. Results demonstrate the need for the development, adaptation, and validation of assessments relevant for informal markets in a diverse range of LMIC contexts to support diets, nutrition, and health globally.

Abstract
With increased burden of malnutrition on global health, there is a need to set clear and transparent priorities for action in food systems at a global and local level. While priority settings methods are available for several adjacent domains, such as nutrition and health policies, setting priorities for food system research has not been documented and streamlined. The challenges involve food systems' multisector, multi-stakeholder and multi-outcome nature. Where data exists, it is not easy to aggregate data from across food system dimensions and stakeholders to make an informed analysis of the overall picture of the food system, as well as current and potential food system trade-offs to inform research and policy. Once research priorities are set, they risk staying on paper and never make their ways to concrete outputs and outcomes. In this paper, we documented and assessed the inclusive process of setting research priorities for a local food system, taking Vietnamese food systems as a case study. From this exercise, we examined how priority setting for food systems research could learn from and improve upon earlier priority setting research practices in other domains. We discussed the lessons for research and policies in local food systems, such as the need for a concrete follow-up plan accompanying the priority setting process.

Abstract
Sub-optimal diets are one of the most important risk factors contributing to the global burden of disease. Developing a better understanding of the drivers of food choice, including the role of individual preferences, is important to address this issue. The objective of this mixed methods research was to identify the relative importance of preferences for different food quality attributes (e.g. nutrition, food safety, price and convenience) that might influence shopping habits and food choice in the context of a rapidly changing peri-urban food environment in Hanoi Province, Viet Nam. A total of 264 women were randomly selected and interviewed using Best-Worst Scaling to elicit preferences among food quality attributes for different food groups (leafy green vegetables, fruits, instant foods, snack foods). A subset of these respondents (n = 40) participated in focus group discussions in order to explore their preferences and food values in more detail. The food quality attributes considered to be most important varied by food group with nutrition and food safety (both immediate and future health) ranking highest for leafy green vegetables and fruits, convenience for instant foods, and taste for snack foods. Price was considered least important across all food groups. Focus group discussions reinforced these results with additional insights particularly regarding trade-offs between nutrition, food safety, convenience, and price. This research demonstrates the feasibility of identifying important drivers of consumption in a South East Asian context using Best-Worst Scaling. These results could help inform the design of behavior change interventions and guide food system policies that seek to shift consumer choices towards healthier diets.
