Conférence en ligne aux Journées Francophones de Nutrition - JFN du 10 au 12/11/2021.; International audience; In urban and peri-urban areas, where waste management is more than ever a major issue, insect farming may be an ecological way to recycle bio-waste in a circular bioeconomy approach. Indeed, someinsect species such as Hermetia illucens can grow on many types of organic substrates and can convert them into valuable byproducts(1). There may be a wide variety of insect bioconversion products since larvae are a natural source of micronutrients, amino acids and antimicrobial compounds. They are also rich in proteins which can be used for animal feed, in fats used for the production of biodiesel, in chitin used in various industries, and they produce a type of manure called frass that can be used as biofertilizer(2). However, besides its ecological and nutritional benefits, risks of insectbased bioconversion should be identified and monitored. Indeed, some chemical contaminants may be found in insect farming environment, in their feeding substrates or can be produced during processing methods(3). Moreover, microbiological contaminants may be found in the farming insect chain(4). Therefore, it is necessary to assess the impact of these contaminants on insect survival and to determine their fate in the insect. It is also important to assess the environmental, social and economic impact of insect-based bioconversion and to determine the consumer acceptability of these new processes and products

Investigating the impact of diet on public health using risk–benefit assessment (RBA) methods that simultaneously consider both beneficial and adverse health outcomes could be useful for shaping dietary policies and guidelines. In the field of food safety and nutrition, RBA is a relatively new approach facing methodological challenges and being subject to further developments. One of the methodological aspects calling for improvement is the selection of components to be considered in the assessment, currently based mainly on non-harmonized unstandardized experts’ judgment. Our aim was to develop a harmonized, transparent, and documented methodological framework for selecting nutritional, microbiological, and toxicological RBA components. The approach was developed under the Novel foods as red meat replacers—an insight using Risk-Benefit Assessment methods (NovRBA) case study, which attempted to estimate the overall health impact of replacing red meat with an edible insect species, Acheta domesticus. Starting from the compositional profiles of both food items, we created a “long list” of food components. By subsequently applying a series of predefined criteria, we proceeded from the “long” to the “short list.” These criteria were established based on the occurrence and severity of health outcomes related to these components. For nutrition and microbiology, the occurrence of health outcomes was evaluated considering the presence of a component in the raw material, as well as the effect of processing on the respective component. Regarding toxicology, the presence and exposure relative to reference doses and the contribution to total exposure were considered. Severity was graded with the potential contribution to the background diet alongside bioavailability aspects (nutrition), the disability-adjusted life years per case of illness of each hazard (microbiology), and disease incidence in the population, potential fatality, and lifelong disability (toxicology). To develop the “final list” of components, the “short list” was refined by considering the availability and quality of data for a feasible inclusion in the RBA model. The methodology developed can be broadly used in food RBA, to guide and reinforce a harmonized selection of nutritional, microbiological, and toxicological components and will contribute to facilitating RBA implementation, enabling the generation of transparent, robust, and comparable outcomes.

Risk-Benefit Assessment (RBA) of Foods is briskly developing to support complex public health decision-making processes related to nutritional, microbiological and toxicological issues. With the intention to tackle public health matters with a comprehensive and integrative approach, methodologies have evolved, and several challenges were identified and must be overcome to facilitate the use of RBA (1–4). The Research Topic on “Advances in Public Health with Risk-Benefit Assessment of Foods” comprises seven articles including original research and reviews, providing recent progress and perspectives in the field. More specifically, it integrates new RBA case studies that make use of diverse health metrics; suggestions on methodological developments to enhance clarity and transparency in the process; insight of integration in a One Health strategy; and novel considerations of how RBA outcomes could be communicated.

This article belongs to the Section Pediatric Nutrition. Cereal-based foods, including breakfast (BC) and infant cereals (IC), are among the first solid foods introduced to infants. BC and IC are sources of macro and micronutrients that have bene ficial effects on health, but can also be sources of harmful chemical and microbiological contaminants and nutrients that may lead to adverse health effects at high consumption levels. This study was performed under the RiskBenefit4EU project with the aim of assessing the health impact associated with consumption of BC and IC by Portuguese children under 35 months. Adverse effects associated with the presence of aflatoxins, Bacillus cereus, sodium and free sugars were assessed against the benefits of fiber intake. We applied a risk–benefit assessment approach, and quantified the health impact of changes in consumption of BC and IC from current to various alternative consumption scenarios. Health impact was assessed in terms of disability-adjusted life years. Results showed that moving from the current consumption scenario to considered alternative scenarios results in a gain of healthy life years. Portuguese children can benefit from exchanging intake of IC to BC, if the BC consumed has an adequate nutritional profile in terms of fiber, sodium and free sugars, with levels of aflatoxins reduced as much as possible.

Climate change is one of the threats to the dairy supply chain as it may affect the microbiological quality of raw milk. In this context, a probabilistic model was developed to quantify the concentration of Escherichia coli in raw milk and explore what may happen to France under climate change conditions. It included four modules: initial contamination, packaging, retailing, and consumer refrigeration. The model was built in R using the 2nd order Monte Carlo mc2d package to propagate the uncertainty and analysed its impact independently of the variability. The initial microbial counts were obtained from a dairy farm located in Saudi Arabia to reflect the impact of hot weather conditions. This country was taken as representative of what might happen in Europe and therefore in France in the future due to climate change. A large dataset containing 622 data points was analysed. They were fitted by a Normal probability distribution using the fitdistrplus package. The microbial growth was determined across various scenarios of time and temperature storage reflecting the raw milk supply-chain in France. Existing growth rate data from literature and ComBase were analysed by the Ratkowsky secondary model. Results were interpreted using the nlstools package. The mean E. coli initial concentration in raw milk was estimated to be 1.31 [1.27; 1.35] log CFU/ mL and was found to increase at the end of the supply chain as a function of various time and temperature conditions. The estimations varied from 1.73 [1.42; 2.28] log CFU/mL after 12 h, 2.11 [1.46; 3.22] log CFU/mL after 36 h, and 2.41 [1.69;3.86] log CFU/mL after 60 h of consumer storage. The number of milk packages exceeding the 2-log French hygiene criterion for E. coli increased from 10% [8;12%] to 53% [27;77%] during consumer storage. In addition, the most significant factors contributing to the uncertainty of the model outputs were identified by running a sensitivity analysis. The results showed that the uncertainty around the Ratkowsky model parameters contributed the most to the uncertainty of E. coli concentration estimates. Overall, the model and its outputs provide an insight on the possible microbial raw milk quality in the future in France due to higher temperatures conditions driven by climate change.

International audience; The consumption of red meat has been associated with colorectal cancer (CRC) and cardiovascular disease (CVD) worldwide. The objective of this study was to assess quantitatively the burden of disease of CRC and CVD due to the consumption of red meat in France. A probabilistic risk assessment model quantifying the risk, deaths and disability adjusted life years (DALY) of both outcomes was built. In the model, uncertainty and variability were propagated separately. The model used data on current CRC and CVD incidence and red meat consumption in France, as well as dose-response from epidemiological studies. Results were given by age class and gender. A total of 19 [95% CI = 8-33] DALY per 100,000 people per year for CRC associated with red meat consumption was estimated. For CVD, 21 [95% CI = 12-32) DALY per 100,000 people per year was estimated. The uncertainty was mainly due to the dose-response, as revealed by a sensitivity analysis. A scenario analysis, performed on red meat intake, highlighted that consumption of less than 65 g per day could limit the risk of CRC and CVD in the most affected sub-populations.

International audience; The world population’s constant increase and the continuous need to ensure food safety and security are among the major challenges to be faced in the next 30 years. In addition, human diet is evolving with a decreased inclusion of proteins from animal sources. In this context, consumption of insects by humans (entomophagy) could be an alternative solution to the intake of protein derived from conventional livestock, due to the lower environmental impact of insect rearing compared to traditional farming. Furthermore, various insect species have promising nutritional profiles regarding both macro and micronutrients. Nowadays, it is recognized that about 2 billion people consume insects at a worldwide scale, with more than 2000 different species to have been reported. Since the beginning of the 2000s, mass rearing of insects for human consumption has been developing all over the world. Nevertheless edible insects are foodstuffs of animal origin and are usually consumed in their entirety, including the digestive tract, meaning that they may contain biological agents with hazardous potential (e.g. bacteria, parasites, viruses, prions, yeasts, molds, mycotoxins, histamine, and antibiotic resistance genes) and they must undergo a thorough analysis. Therefore, establishing the synthesis of the current knowledge on entomophagy and the related biological hazards is the main purpose of this review.

Food of animal origin, especially meat products, represent the main vehicle of foodborne pathogens and so are implicated in foodborne outbreaks. Poultry meat is a widely consumed food in various forms, but it is also a reservoir of thermotolerant Campylobacter and Salmonella bacterial species. To assess human health risks associated with pathogenic bacteria in poultry meat, the use of quantitative microbial risk assessment (QMRA) has increased over the years as it is recognized to address complex food safety issues and is recommended by health authorities. The present project reviewed poultry meat QMRA, identified key steps of the farm-to-fork chain with significant impacts on food safety, highlighted current knowledge gaps, and provided risk mitigation advices. A PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-based systematic analysis was carried out and enabled the collection of 4056 studies including 42 QMRA kept for analysis after screening. The latter emphasized Campylobacter spp. and Salmonella spp. contaminations during the consumer stage as the main concern. The role of consumer handling on cross-contamination and undercooking events were of major concern. Thus, proper hygiene and safety practices by consumers have been suggested as the main intervention and would need to be followed with regular surveys to assess behavior changes and reduce knowledge gaps. ispartof: FOODS vol:9 issue:11 ispartof: location:Switzerland status: published

Entomophagy has been part of human diets for a long time in a significant part of the world, but insects are considered to be a novel food everywhere else. It would appear to be a strategic alternative in the future of human diet to face the challenge of ensuring food security for a growing world population, using more environmentally sustainable production systems than those required for the rearing of other animals. Tenebrio molitor, called yellow mealworm, is one of the most interesting insect species in view of mass rearing, and can be processed into a powder that ensures a long shelf life for its use in many potential products. When considering insects as food or feed, it is necessary to guarantee their safety. Therefore, manufacturers must implement a Hazard Analysis Critical Control plan (HACCP), to limit risks for consumers&rsquo, health. The aim of this case study was to develop a HACCP plan for Tenebrio molitor larvae powders for food in a risk-based approach to support their implementation in industry. Specific purposes were to identify related significant biological hazards and to assess the efficiency of different manufacturing process steps when used as Critical Control Points. Then, combinations of four different processes with four potential uses of powders by consumers in burger, protein shake, baby porridge, and biscuits were analyzed with regard to their safety.

International audience; Each year in Europe, meat is associated with 2.3 million foodborne illnesses, with a high contribution from beef meat. Many of these illnesses are attributed to pathogenic bacterial contamination and inadequate operations leading to growth and/or insufficient inactivation occurring along the whole farm-to-fork chain. To ensure consumer health, decision-making processes in food safety rely on Quantitative Microbiological Risk Assessment (QMRA) with many applications in recent decades. The present study aims to conduct a critical analysis of beef QMRAs and to identify future challenges. A systematic approach, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, was used to collate beef QMRA models, identify steps of the farm-to-fork chain considered, and analyze inputs and outputs included as well as modelling methods. A total of 2343 articles were collected and 67 were selected. These studies focused mainly on western countries and considered Escherichia coli (EHEC) and Salmonella spp. pathogens. Future challenges were identified and included the need of whole-chain assessments, centralization of data collection processes, and improvement of model interoperability through harmonization. The present analysis can serve as a source of data and information to inform QMRA framework for beef meat and will help the scientific community and food safety authorities to identify specific monitoring and research needs.

National audience; Climate change is expected to affect many different sectors across the food supply chain. The current review paper presents an overview of the effects of climate change on the microbial safety of the dairy supply chain and suggest potential mitigation strategies to limit the impact. Raw milk, the common raw material of dairy products, is vulnerable to climate change, influenced by changes in average temperature and amount of precipitation. This would induce changes in the microbial profile and heat stress in lactating cows, increasing susceptibility to microbial infection and higher levels of microbial contamination. Moreover, climate change affects the entire dairy supply chain and necessitates adaptation of all the current food safety management programs. In particular, the review of current prerequisite programs might be needed as well as revisiting the current microbial specifications of the receiving dairy products and the introduction of new pretreatments with stringent processing regimes. The effects on microbial changes during distribution and consumer handling also would need to be quantified through the use of predictive models. The development of Quantitative Microbial Risk Assessment (QMRA) models, considering the whole farm-to-fork chain to evaluate risk mitigation strategies, will be a key step to prioritize actions towards a climate change-resilient dairy industry.

“RiskBenefit4EU ‐ Partnering to strengthen the risk‐benefit assessment within EU using a holistic approach” was a knowledge transfer project funded by the European Food Safety Authority (EFSA) that integrated a multidisciplinary team from Portugal, Denmark and France. This project aimed to strengthen the EU capacity to assess risks and benefits associated with human food consumption, considering the fields of toxicology, microbiology and nutrition. To train the recipient partners from Portugal on Risk‐Benefit Assessment (RBA), a capacity‐building program was implemented, including three main activities: theoretical training on RBA concepts; hands‐on training applying concepts to a case‐study using methods and tools displayed; and scientific missions to provide advanced training in specific domains of RBA. The developed RBA strategy was applied to a case study focusing on the RBAof the consumption of cereal‐based products by Portuguese young children. Risks due to aflatoxins, Bacillus cereus, sodium and free sugars, were evaluated, as well as the benefit of fibreintake. Five different scenarios of infant cereals and/or breakfast cereals consumption were considered, and the assessment showed that moving from the current consumption to the considered alternative scenarios wouldresult in a gain of healthy‐life years. The RiskBenefit4EU project applied a collaborative method to train a new team to perform RBAs of foods and face the challenge of cooperation between experts from different disciplines. During the process of capacity building, a movement from conceptual knowledge towards action was an essential step to effectively increase performance. The developed framework facilitated the case‐study accomplishment and contributed to build a shared and harmonized RBA approach and culture. The suggested strategy can now be re‐used to capacitate other teams in RBA,and can be considered as a basis to build upon.

International audience; Background: Food safety and quality can be compromised by microbiological contamination caused by a variety of pathogenic and spoilage microorganisms present in the production environment. The combination of monitoring both food products and the production environment is a lever to increase food safety and quality. Environmental monitoring programs (EMPs) implemented in food industries allow evaluating the clout of the microbial controls in food processing plants.Scope and approach: The aim of the present review is to systematically assess, using the Scoping review and PRISMA method, available information and strategies to build efficient EMP in the food industry. Key findings and conclusions: Despite the available literature on the implementation of EMPs, there is to date no ready-to-use method and its application strongly depends on the characteristics of the processing plant. A common three-step approach has been proposed for the construction of EMP, whatever the food sector including a pre-analytical, an analytical and a post-analytical step. The pre-analytical step aims to design strategies for the implementation of efficient EMP, considering the hazards and the risk associated with food product and food plant. The analytical step consists of sampling stages using cultural or molecular approaches. Finally, the postanalytical step, concerns the management of data collected. EMPs are dynamic programs that undergo change over time and must be updated on a regular basis in order to guarantee their fit for purpose.

International audience; The safety and quality of infant milk, whether it is breast milk (BM) or infant formula (IF), are a major concern for parents and public health authorities. BM is recommended as the gold standard at WHO level. However, nowadays IF appears as an essential alternative in Western countries, challenging producers to optimise nutritional quality and safety of IF. The aim of the present paper is to give an overview on the assessment and comparison of risks and benefits associated with BM and IF consumption. To date, this intensively debated subject has been mainly investigated. It has been shown that both diets could be sources of beneficial health effects in terms of nutrition and also risks in terms of chemical safety. Moreover, microbiologists have demonstrated that IF consumption can cause illness due to product contamination or inappropriate milk preparation. The paper concludes on the bottlenecks and gaps which should be investigated to further progress the quantification of the impact of early diet on infant health. Performing a multi-disciplinary risk-benefit assessment with DALY as endpoint, might be a future option to help prioritise management options.

A probabilistic and interdisciplinary risk–benefit assessment (RBA) model integrating microbiological, nutritional, and chemical components was developed for infant milk, with the objective of predicting the health impact of different scenarios of consumption. Infant feeding is a particular concern of interest in RBA as breast milk and powder infant formula have both been associated with risks and benefits related to chemicals, bacteria, and nutrients, hence the model considers these three facets. Cronobacter sakazakii, dioxin-like polychlorinated biphenyls (dl-PCB), and docosahexaenoic acid (DHA) were three risk/benefit factors selected as key issues in microbiology, chemistry, and nutrition, respectively. The present model was probabilistic with variability and uncertainty separated using a second-order Monte Carlo simulation process. In this study, advantages and limitations of undertaking probabilistic and interdisciplinary RBA are discussed. In particular, the probabilistic technique was found to be powerful in dealing with missing data and to translate assumptions into quantitative inputs while taking uncertainty into account. In addition, separation of variability and uncertainty strengthened the interpretation of the model outputs by enabling better consideration and distinction of natural heterogeneity from lack of knowledge. Interdisciplinary RBA is necessary to give more structured conclusions and avoid contradictory messages to policymakers and also to consumers, leading to more decisive food recommendations. This assessment provides a conceptual development of the RBA methodology and is a robust basis on which to build upon.

Background: Human diet may present both risks and benefits to consumers’ health. Risk-benefit assessment of foods (RBA) intends to estimate the overall health impact associated with exposure (or lack of exposure) to a particular food or food component. Scope and approach: “RiskBenefit4EU – Partnering to strengthen the risk-benefit assessment within EU using a holistic approach” (RB4EU) is a project funded by the European Food Safety Authority (EFSA) that integrates a multidisciplinary team from Portugal, Denmark and France. This project aims to strengthen the EU capacity to assess and integrate food risks and benefits regarding toxicology, microbiology and nutrition. One of the specific objectives of RB4EU was to build capacity in RBA among the recipient partners from Portugal. In order to achieve this objective, a capacity building strategy including theoretical and hands-on training and the development of a case-study were established. This paper aims to present the strategy used in the RB4EU project to build capacity within RBA, including the main training approaches and the lessons learned. Key findings and conclusions: The capacity-building program included three main activities: theoretical training, focusing on RBA concepts; hands-on training, applying the acquired concepts to a concrete case-study, using the methods and tools displayed; and scientific missions, intending to provide advanced training in specific domains of RBA. The developed strategy can be used in the future to build capacity within RBA. Highlights: Risk-benefit assessment (RBA) aims to estimate health benefits and risks of foods; Capacity building actions contribute to acquire scientific foundation on RBA; RiskBenefit4EU project aims to strengthen the EU capacity to perform RBA; A capacity building strategy was developed and implemented under RiskBenefit4EU; Lessons learned through this capacity building process were reviewed and discussed. This work was supported by the “RiskBenefit4EU – Partnering to strengthen the risk-benefit assessment within EU using a holistic approach” funded by EFSA Partnering Grants (Grant Agreement Number – GA/EFSA/AFSCO/2017/01 – GA02). 1 Ricardo Assunção, Paula Alvito and Carla Martins are grateful to the support of CESAM funded by the Portuguese Foundation for Science and Technology (UID/AMB/50017/2013), through national funds, and the co-funding by the FEDER (POCI-01-0145-FEDER-00763), within the PT2020 Partnership Agreement and Compete 2020. info:eu-repo/semantics/publishedVersion

International audience; Whilst risk management measures, including food policy, are developed for the protection of public health and the environment, they may also lead to a reduction in health benefits. Policy decisions require then consideration of these necessary trade-offs, which leads to an increasing need to apply formal risk-benefit assessment (RBA) of foods. In this context, the European Food Safety Authority sponsored a Risk-Benefit Assessment Workshop on "past, current and future developments within the risk-benefit assessment of foods (RBA)" held in May 2017. The overall aims of the RBA Workshop were to discuss existing methods, challenges and needs within RBA, and to draft a roadmap for future development of RBA. The specific objectives were to i) identify RBA activities in Europe and globally; ii) discuss how to further develop and optimize RBA methodology; iii) identify challenges and opportunities within RBA; and iv) increase collaboration internationally. The two-day workshop gathered 28 participants from 16 institutions in 11 countries. It included technical presentations of RBA methods and case studies, and two break-out sessions for group discussions. All participants agreed that RBA has substantial potential to inform risk-management decisions in the areas of food safety, nutrition and public health. Several activities to optimize further developments within RBA were suggested. This paper provides a summary of workshop presentations, a discussion of challenges that limit progress in this area, and suggestions of next steps for this promising approach supporting a science-based decision process in the area of risk-benefit management of foods.

Foodborne microbial diseases have a significant impact on public health, leading to millions of human illnesses each year worldwide. Pork is one of the most consumed meat in Europe but may also be a major source of pathogens introduced all along the farm-to-fork chain. Several quantitative microbial risk assessment (QMRA) have been developed to assess human health risks associated with pork consumption and to evaluate the efficiency of different risk reduction strategies. The present critical analysis aims to review pork QMRA. An exhaustive search was conducted following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) methodology. It resulted in identification of a collection of 2489 papers including 42 on QMRA, after screening. Among them, a total of 29 studies focused on Salmonella spp. with clear concern on impacts at the slaughterhouse, modeling the spreading of contaminations and growth at critical stages along with potential reductions. Along with strict compliance with good hygiene practices, several potential risk mitigation pathways were highlighted for each slaughterhouse step. The slaughterhouse has a key role to play to ensure food safety of pork-based products but consideration of the whole farm-to-fork chain is necessary to enable better control of bacteria. This review provides an analysis of pork meat QMRA, to facilitate their reuse, and identify gaps to guide future research activities. ispartof: FOODS vol:9 issue:11 ispartof: location:Switzerland status: published

International audience; Tap water is used in France to reconstitute powder infant formula, although it is not sterile and possibly contaminated by microbiological and chemical hazards. The present study aims to quantify risks of using tap water in France for the preparation of infant formula, during the first six months of life. Cryptosporidium and arsenic were selected as hazards of greatest concern in microbiology and chemistry, respectively. A probabilistic model was developed using French (when available) and European (alternatively) data. Second order Monte Carlo simulation was used to separate uncertainty and variability of inputs. Outputs were expressed at the individual level as probability of illness and at the population level, using a common metric, the DALY (Disability Adjusted Life Year). Two scenarios of milk preparation were considered: with un-boiled or boiled tap water. Consuming infant formula rehydrated with un-boiled tap water during the first six months of life led to a total of 2250 DALYs per 100,000 infants (90% uncertainty interval [960; 7650]) for Cryptosporidium due to diarrhea, and 1 DALY [0.4; 2] for arsenic due to expected lifetime risk of lung and bladder cancer as a result of early exposure in life. For the entire population, boiling water would suppress the risk from Cryptosporidium. In contrast, the incremental cancer risk was low at the population level but elevated for 5% of the population exposed to high levels of arsenic. A stringent monitoring of tap water supply points should be continued. This multi-risk assessment model could help public health authorities and managers in evaluating both microbiological and chemical safety issues associated with using infant formula prepared with tap water.

International audience; The objective of this article is to bring scientific background as well as practical hints and tips to guide risk assessors and modelers who want to develop a quantitative Microbiological Risk Assessment (MRA) in an industrial context. MRA aims at determining the public health risk associated with biological hazards in a food. Its implementation in industry enables to compare the efficiency of different risk reduction measures, and more precisely different operational settings, by predicting their effect on the final model output. The first stage in MRA is to clearly define the purpose and scope with stakeholders, risk assessors and modelers. Then, a probabilistic model is developed; this includes schematically three important phases. Firstly, the model structure has to be defined, i.e. the connections between different operational processing steps. An important step in food industry is the thermal processing leading to microbial inactivation. Growth of heat treated surviving microorganisms and/or post-process contamination during storage phase is also important to take into account. Secondly, mathematical equations are determined to estimate the change of microbial load after each processing step. This phase includes the construction of model inputs by collecting data or eliciting experts. Finally, the model outputs are obtained by simulation procedures, they have to be interpreted and communicated to targeted stakeholders. In this latter phase, tools such as what-if scenarios provide an essential added value. These different MRA phases are illustrated through two examples covering important issues in industry. The first one covers process optimization in a food safety context, the second one covers shelf-life determination in a food quality context. Although both contexts required the same methodology, they do not have the same end-point: up to the human health in the foie gran case-study illustrating here a safety application, up to the food portion in the brioche case-study illustrating here a quality application.
