This article draws on fieldwork among patients pursuing healing using macrobiotic diets at a Buddhist temple clinic not far from Ho Chi Minh City, Vietnam. It examines the (re-)emergence of macrobiotic diets as a movement for “nurturing life” (duõng sinh) in modeern Vietnam. By examining the use of macrobiotic diets among this temple's patients and followers, the article unravels popular discourses of food and health, and their intertwining relationships with conceptions of chronic diseases in contemporary Vietnamese society. The popularity of this temple as an alternative therapeutic centre for people with chronic conditions also sheds light on notions of illness, healing processes, and religious beliefs. The rise of macrobiotics as an alternative diet and lifestyle reveals people's uncertainties and mistrust amid many prevalent problems in contemporary Vietnam, such as food safety concerns. Altogether, “nurturing life” activities offer strategies for individuals to adapt to a rapidly changing social context.

The incredible growth of China's cattle, sheep and dairy production is a visible phenomenon of the past twenty years, but its foundations were laid decades earlier. Seeking to industrialize its hinterland, and exploit its vast wealth of grazing livestock, China created slaughtering and processing facilities across its northern grasslands during the 1950s. Since the 1980s, much of this infrastructure has been privatized by companies which, like their predecessors, seek efficiency through economies of scale. Brutal competition over price and constant arrival of new domestic and foreign players have encouraged the integration of processing chains, but also sidelined small operators, and created gaps in safety best epitomized by the 2008 tainted milk scandal. Despite steps taken to “green” the production chain, it remains to be seen if such gaps have been adequately filled.

We study the impact of endowments and expectations on reference point formation and measure the value of food safety certification in the context of fish trading on real markets in Nigeria. In our field experiment, consumers can trade a known food item for a novel food item that is superior in terms of food safety––or vice versa. Endowments matter for reference point formation, but we also document a reverse endowment effect for a subsample of respondents. The effect of expectations about future ownership is weak and mixed. While expectations seem to affect bidding behavior for subjects “trading up” to obtain the certified food product (a marginally significant effect), it does not affect bids for subjects “trading down” to give up this novel food item. Finally, willingness to pay for safety certified food is large for our respondents—our estimate of the premium is bounded between 37 and 53% of the price of conventional, uncertified food.

This research paper presents the characterization of an enterocin-producing Enterococcus durans MF5 isolate and the determination of the in vitro antilisterial activity of enterocin produced by this isolate, named Ent-MF5. PCR-based screening for bacteriocin biosynthetic genes revealed that E. durans MF5 harbors multiple enterocin-encoding genes (ent A, B, P and X), classified as class II bacteriocins and enterocin-P of Enterococcus faecium (sharing up to 99% similarity at the genetic level). E. durans MF5 is sensitive to eight clinically important antibiotics and does not possess cytolysin activator -cylA, gelatinase -gelE and hyaluronidase -hylA virulence genes. The antilisterial activity of Ent-MF5 was abolished by trypsin, α-chymotrypsin, protease and proteinase-K. Ent-MF5 showed thermal and pH stability. In addition, the activity of Ent-MF5 was unaffected in the presence of various surfactants (1% SDS, Triton X-100, Tween 20, and Tween 80). Ent-MF5 exhibited antimicrobial activity against Listeria monocytogenes, Listeria innocua, Listeria ivanovii and Listeria seeligeri at concentrations as low as 0.13 μg/ml. Ent-MF5 had a bactericidal effect against L. monocytogenes with a significant reduction in surviving cells at concentrations equal to or greater than 0.13 μg/ml. A 75–100% reduction in L. monocytogenes growth and bactericidal effect determined by CFU counts was observed following treatment with Ent-MF5 at 4.47 μg/ml at time points starting at 2 and 4 h, respectively. Ent-MF5 action is associated with Listeria cell membrane damage, as observed by flow cytometry and fluorescence microscopy. Thus, the effective antilisterial activity and stability of Ent-MF5 presents promising perspectives for application as biopreservatives in the food industry.

The European Food Safety Authority (EFSA) provides independent scientific advice to EU risk managers on a wide range of food safety issues and communicates on existing and emerging risks in the food chain. This advice helps to protect consumers, animals and the environment. Data are essential to EFSA’s scientific assessments. EFSA collects data from various sources including scientific literature, biological and chemical monitoring programmes, as well as food consumption and composition databases. EFSA also assesses data from authorisation dossiers for regulated products submitted by the industry. To continue delivering the highest value for society, EFSA keeps abreast of new scientific, technological and societal developments. EFSA also engages in partnerships as an essential means to address the growing complexity in science and society and to better connect and integrate knowledge, data and expertise across sectors. This paper provides insights into EFSA’s data-related activities and future perspectives in the following key areas of EFSA’s 2027 strategy: one substance-one assessment, combined exposure to multiple chemicals, environmental risk assessment, new approach methodologies, antimicrobial resistance and risk–benefit assessment. EFSA’s initiatives to integrate societal insights in its risk communication are also described.

In July 2022, a genetically linked and geographically dispersed cluster of 12 cases of Shiga toxin-producing Escherichia coli (STEC) O103:H2 was detected by the UK Health Security Agency using whole genome sequencing. Review of food history questionnaires identified cheese (particularly an unpasteurized brie-style cheese) and mixed salad leaves as potential vehicles. A case–control study was conducted to investigate exposure to these products. Case food history information was collected by telephone. Controls were recruited using a market research panel and self-completed an online questionnaire. Univariable and multivariable analyses were undertaken using Firth Logistic Regression. Eleven cases and 24 controls were included in the analysis. Consumption of the brie-style cheese of interest was associated with illness (OR 57.5, 95% confidence interval: 3.10–1,060). Concurrently, the production of the brie-style cheese was investigated. Microbiological sample results for the cheese products and implicated dairy herd did not identify the outbreak strain, but did identify the presence of stx genes and STEC, respectively. Together, epidemiological, microbiological, and environmental investigations provided evidence that the brie-style cheese was the vehicle for this outbreak. Production of unpasteurized dairy products was suspended by the business operator, and a review of practices was performed.

In May 2017, whole-genome sequencing (WGS) became the primary subtyping method for Salmonella in Canada. As a result of the increased discriminatory power provided by WGS, 16 multi-jurisdictional outbreaks of Salmonella associated with frozen raw breaded chicken products were identified between 2017 and 2019. The majority (15/16) were associated with S. enteritidis, while the remaining outbreak was associated with S. Heidelberg. The 16 outbreaks included a total of 487 cases with ages ranging from 0 to 98 years (median: 24 years); 79 hospitalizations and two deaths were reported. Over the course of the outbreak investigations, 14 frozen raw breaded chicken products were recalled, and one was voluntarily withdrawn from the market. After previous changes to labelling and the issuance of public communication for these products proved ineffective at reducing illnesses, new industry requirements were issued in 2019, which required the implementation of measures at the manufacturing/processing level to reduce Salmonella to below detectable amounts in frozen raw breaded chicken products. Since implementation, no further outbreaks of Salmonella associated with frozen breaded chicken have been identified in Canada, a testament to the effectiveness of these risk mitigation measures.

Imperfect information on food safety and risk has created a system with less safety than the public wants. Consumers cannot pay for the level of safety they desire. Tort under-compensates for foodborne illness due to difficulty proving causation. When market controls are ineffective at producing the level of safety desired by consumers, the classic approach is government regulation. However, government regulators face challenges that impede the translation of scientific knowledge into regulatory controls. This often results in an equilibrium of private interests and bureaucratic interests rather than the public interest. To restore republican deliberation on food safety we need greater citizen involvement in the decision-making. Access to the courts is an effective means for citizens to participate directly in the decisions affecting food safety; thus, a private cause of action to our national food safety laws is proposed.

Young, older, pregnant, and immunocompromised (YOPI) people are most vulnerable to foodborne illnesses due to impaired or underdeveloped immune systems(1). There is a lack of information regarding how YOPI groups access, receive or use information about food safety, what influences their food safety behaviour, and their preferences for receiving food safety advice. The objective of this research was to develop a better understanding of how YOPI consumers in New Zealand access and use food safety information, the types and sources of food safety information used, how information and advice are obtained, and how these influence their decision-making about food safety practices and related behaviours. Research questions were guided by a rapid review of literature. Twenty qualitative focus groups (comprising of either young, old, pregnant, or immunocompromised individuals) based in one of three locations in New Zealand were conducted. This was complemented with data from health care providers from relevant sectors (nutritionists, dietitians, aged care providers, cancer nurses, Well Child Tamariki Ora providers, and midwives). Recruitment included a focus on ethnic groups (Māori and Pasifika) to ensure diversity of experiences and perspectives were represented in the research and to reflect NZFS’s interest in developing fit-for-purpose messages and resources for these YOPI populations. Thematic and segmentation analysis was conducted to understand current food safety behaviours and how to best communicate food safety matters. Typologies of participants were developed by grouping participants based on common features: attitudes, beliefs, and experiences. The research revealed most participants are comfortable with their food safety practices and reported habitual behaviours. Many YOPI did not perceive themselves to be at a greater risk of foodborne illness, particularly older people. A key finding was that access to information does not necessarily lead to behaviour change. Groups undergoing periods of change (immunocompromised, pregnant and young) were more likely to seek additional information. Families and health professionals are trusted sources of information, with all groups reporting some use of the internet as an information source. An individual’s risk perception was the main motivating factor for obtaining and following advice. Habit, cost of food, and lack of information were key barriers to obtaining or acting on information, along with pregnant people reporting social pressures as a reason to not obtain or act on relevant advice. In general, there are three key types of food-safety messaging all groups would like to receive: situation-specific advice; information received alongside other key information (e.g., starting solids); and general information for the whole population. Gaining insights into YOPI preferences on food safety matters can aid the development of appropriate communication and engagement methods of the risks and impacts of food safety matters to vulnerable people.

Integrating animals into a farm supports a closed or semi-closed production system where nutrients are recycled and off-farm inputs are reduced. In comparison to other livestock, chickens can be a low-investment option for animal-crop integration of small-scale, diversified, vegetable farms. Although crop-animal integration poses many potential benefits to farms, soils, and the environment, there are significant food safety risks when considering the production of vegetables in close proximity to raw manure. The objectives of this study were to examine the effects of poultry integration with meat chickens (broilers) in two different seasons on soil health, food safety, vegetable yield, and poultry feed efficiency in organic vegetable cropping systems. We explored these effects in an open field study with three rotation treatments (two that integrated chickens and a no-chicken control): vegetables-cover crop (V-CC; control treatment), vegetables-cover crop-poultry (V-CC-P), and vegetables-poultry-cover crop (V-P-CC). In response to crop rotation, over three years, we monitored soil nutrient status, soil microbial biomass carbon (MBC), permanganate oxidizable carbon (POXC), and microbial catabolic potential and diversity using Biolog® microplates. The presence or absence of foodborne pathogens in soil and vegetables was also measured. Nitrate–nitrogen (NO3–N) was higher in V-P-CC in year 2 as compared to both V-CC and V-CC-P (P = 0.001 and <0.001, respectively). After poultry removal in the summer of year 2 and year 3 V-P-CC was on average two times higher in NO3–N as compared to V-CC and V-CC-P, respectively. After chicken removal in the autumn of year 3 V-CC-P was 2.1 and 1.8 times higher in NO3–N as compared to V-CC and V-P-CC, respectively. On average phosphorus (P) increased by 45% in year 2 and by 13.2% in year 3. Microbial biomass carbon (MBC) increased from after harvest (summer) in year 1 to the end of the season (autumn) of year 2 from 219.75 to 303.23 mg carbon (C) kg−1. Integrating poultry increased MBC by 25%, on average between both treatments across all sampling dates, compared to the V-CC (P = 0.042). The vegetable-cover crop control (V-CC) preferentially used carbohydrates, compared to V-P-CC which corresponded to greater amino acid usage. Escherichia coli O157:H7 was detected in all plots in the spring of year 3 and select replications of plots in the autumn of year 3. Salmonella spp. was found in one plot in year 2. No pathogens were detected on the spinach crop when leaf surfaces were tested. Integrating chickens into organic vegetable crop rotations increases NO3–N and has the potential for off-farm fertilizer reductions if time and stocking density are further examined. However, poultry feed is often an off-farm input and should be considered when determining the true N input of this system. Soil health may be improved, but MBC and other soil health indicators should be monitored with longer-term rotations. There are food safety risks that come with the integration of chickens into vegetable production and fields should be treated as if raw manure has been applied. Despite the potential benefits of integrating poultry into vegetable crop rotations, more research on these systems is required to determine optimum integration strategies that provide maximum benefit to the producer, the animals, and the environment.

This study aimed to review hazard analysis and critical control points (HACCP) in the dairy industry for the production of yogurt. The food safety management system (FSMS) was implemented over the last several decades with several amendments. The need for practical and proactive procedures in the dairy industry was identified so that HACCP implementation could ensure that consumers would always have safe food. The concept of HACCP is a systemic and science-based method that can result in safe dairy products such as yogurt based on the complete analysis of manufacturing processes, recognition of hazards potentially present at all stages of production, and risk prevention. In yogurt production, raw milk receipt, pasteurization, packaging, and storage are the steps most susceptible to contamination and were considered critical control points. Further steps also need to be implemented to achieve other related control measures, and these will be discussed.

Non-aureus staphylococci (NAS) are gaining importance in mastitis and public health, and some NAS have been reclassified as mammaliicocci (NASM). Bovine milk production has a major influence on the world economy, being an essential source of income for small, medium and large producers, and bovine mastitis caused by NASM can cause an economic impact. Mastitis generates financial losses due to reduced revenue, increased veterinary costs and expenses associated with animal slaughter. However, it is also a public health issue involving animal health and welfare, human health and the ecosystem. Furthermore, it is an increasingly common infection caused by NASM, including antimicrobial-resistant strains. Despite all these adverse effects that NASM can cause, some studies also point to its protective role against mastitis. Therefore, this review article addresses the negative and positive aspects that NASM can cause in bovine mastitis, the virulence of the disease and resistance factors that make it difficult to treat and, through the One Health approach, presents a holistic view of how mastitis caused by NASM can affect both animal and human health at one and the same time.

We collected infant food samples from 714 households in Kisumu, Kenya, and estimated the prevalence and concentration of Enterococcus, an indicator of food hygiene conditions. In a subset of 212 households, we quantified the change in concentration in stored food between a morning and afternoon feeding time. In addition, household socioeconomic characteristics and hygiene practices of the caregivers were documented. The prevalence of Enterococcus in infant foods was 50% (95% confidence interval: 46.1 - 53.4), and the mean log10 colony-forming units (CFUs) was 1.1 (SD + 1.4). No risk factors were significantly associated with the prevalence and concentration of Enterococcus in infant foods. The mean log10 CFU of Enterococcus concentration was 0.47 in the morning and 0.73 in the afternoon foods with a 0.64 log10 mean increase in matched samples during storage. Although no factors were statistically associated with the prevalence and the concentration of Enterococcus in infant foods, household flooring type was significantly associated with an increase in concentration during storage, with finished floors leading to 1.5 times higher odds of concentration increase compared to unfinished floors. Our study revealed high prevalence but low concentration of Enterococcus in infant food in low-income Kisumu households, although concentrations increased during storage implying potential increases in risk of exposure to foodborne pathogens over a day. Further studies aiming at investigating contamination of infant foods with pathogenic organisms and identifying effective mitigation measures are required to ensure infant food safety.

Many foodborne illness outbreaks originate in food service establishments. We tested two behavioural interventions designed to improve the duration and quality of handwashing. We ran a three-armed parallel trial in a laboratory kitchen, from 7 March to 27 May 2022. Participants were n = 195 workers who handle food. We randomly allocated participants to three groups: Timer – tap-mounted timer that counted seconds while participants washed their hands; Precommitment – agreed to five statements on good hand hygiene before attending the kitchen; and Control. Participants completed a food preparation task under time pressure. Cameras focused on the sink captured handwashing. Outcome measures were number of times participants washed their hands; number of times they washed their hands using soap; number of times they washed using soap and washed the backs of their hands; and mean duration of handwashing attempts using soap. Participants in Timer washed their hands for 1.9 s longer on average than Control (β = 2.20, 95% CI = 0.34-4.06, p = 0.021). Participants in Precommitment washed their hands for 2.5 s longer on average than Control (β = 2.30, 95% CI = 0.33-4.27, p = 0.022). We found no statistically significant differences on any other outcome measure.

Increasingly most people have their meals outside their homes and are vulnerable to illnesses caused by unsafe foods. Unsafe food preparation and supply by vendors have made food safety a concern for public health. The present study evaluated the nutrition knowledge, attitude and food safety and hygienic practices of street food vendors (SFVs) in Northern Ghana. An analytical cross-sectional study design was conducted among 424 SFVs, and the data were collected using questionnaires and observation. The mean ± sd nutrition knowledge score of the SFVs was 7⋅08 ± 1⋅75 in which the majority of the participants (68⋅6 %) knew foods that help fight diseases and build immunity. The mean ± sd food safety and hygienic practice score was 7⋅61 ± 2⋅66 with more than half of the participants reportedly not using hand gloves while preparing and serving food. Factors that were associated with food safety and hygienic practices of the SFVs were level of education (β = −0⋅36, P < 0⋅001), number of hours worked (β = 0⋅15, P = 0⋅002), food hygiene and safety knowledge (β = 0⋅21, P = 0⋅002), having a business certificate (β = −0⋅15, P = 0⋅004) and having medical check-up (β = 0⋅11, P = 0⋅029). The food safety and hygienic practices of the SFVs may constitute a food safety risk to consumers. Improving food safety and hygiene knowledge may be important but regular monitoring and check-up by the FDA could result in SFVs following the required food safety and hygienic practices.

Why do policy experimentation regimes breakdown? And, if there are recognizable patterns of experimental failure, what might explain the variation? Focusing on aviation, finance and food safety, this article considers why a policy style that has been credited with China's successes in the past is failing to address governance challenges in these sectors at present. The article moves beyond discussions of policy mis-implementation by reframing experimental failure as a case of policy maladaptation under conditions of complexity and ambiguity. Maladaptation describes how approaches used in previous periods to foster adaptation can inadvertently make a system less resilient in the future. The analysis shows how the degree of consolidation of previously successful experimental regimes lends itself to certain types of maladaptation in the present: consolidated regimes are unable to generate policy alternatives (aviation), moderately consolidated regimes are maladapted for selection (finance), and unconsolidated regimes impede niche creation (food safety).

This study examined relationships between foodborne outbreak investigation characteristics, such as the epidemiological methods used, and the success of the investigation, as determined by whether the investigation identified an outbreak agent (i.e. pathogen), food item and contributing factor. This study used data from the Centers for Disease Control and Prevention's (CDC) National Outbreak Reporting System and National Environmental Assessment Reporting System to identify outbreak investigation characteristics associated with outbreak investigation success. We identified investigation characteristics that increase the probability of successful outbreak investigations: a rigorous epidemiology investigation method; a thorough environmental assessment, as measured by number of visits to complete the assessment; and the collection of clinical samples. This research highlights the importance of a comprehensive outbreak investigation, which includes epidemiology, environmental health and laboratory personnel working together to solve the outbreak.

This research paper addresses the hypothesis that powdered milk may contain amyloid fibrils. Amyloids are fibrillar aggregates of proteins. Up to this time, research on the presence of amyloids in food products are scarce. To check the hypothesis we performed thioflavin T fluorescence assay, X-ray powder diffraction, atomic force microscopy and fluorescence microscopy imaging. Our preliminary results show that commercially available milks contain fibrils that have features characteristic to amyloids. The obtained results can be interpreted in two opposite ways. The presence of amyloids could be considered as a hazard due to the fact that food products may induce amyloid related diseases. On the other hand, the presence of amyloids in traditionally consumed foodstuffs could serve as proof that fibrils of food proteins do not pose a threat for consumers.

Stressful housing and management practices affect animals, potentially increasing their receptiveness to pathogens. Since some pathogens do not lead to clinical signs of sickness, subclinical pigs could enter the food-chain, contaminating carcases and offal at slaughter, representing a threat to human health. Here, we assess the feasibility of a new approach (using animal-based welfare outcomes) to investigate the association between the animal welfare status of finishing pigs on-farm and the occurrence of Yersinia enterocolitica and Salmonella enterica in slaughtered pigs in Northern Italy. Thirty batches of finishing pigs were assessed for animal-, resource- and management-based measures according to the Welfare Quality® protocol for pigs on-farm and at slaughter. A sample of five individuals per batch was tested for Y. enterocolitica and S. enterica in tonsils and in mesenteric lymph nodes, respectively, and gross pathological changes were recorded. Environmental faecal samples per batch on-farm were tested for the same pathogens. Univariable logistic regression models were used to investigate the association between batches of pigs that were positive to Y. enterocolitica and S. enterica and indicators of poor welfare. The animal-based measures of welfare, greater on-farm mortality and poor human-animal relationship, were found to be associated with Y. enterocolitica. This study provides a good indication of the validity of this approach, but there is a need for larger-scale studies in the future to confirm the magnitude of the associations between these animal welfare and food safety indicators.
