Overview of recalls, withdrawals and safety alerts with microbial pathogens in the EU and US in 2012-2017. EU data were extracted from RASFF (2020) and US data were extracted from FDA (2020).
There is a great interest in the food industry to perform validations in a manner that would be accepted by all parties involved, for example, authorities and customers.
Low moisture foods are foods that:
- are naturally very low in moisture,
- have had water removed from them,
- have a higher moisture content, but that contain agents that prevent the moisture from being available to microorganisms to allow their growth.
In this work, the "production environment" includes production equipment, production surfaces, floors/walls/ceilings, and the air within the production area.Scientific abstract Expand
Processing environment monitoring is gaining increasing importance in the context of food safety management plans/HACCP programs, since past outbreaks have shown the relevance of the environment as contamination pathway, therefore requiring to ensure the safety of products. However, there are still many open questions and a lack of clarity on how to set up a meaningful program, which would provide early warnings of potential product contamination. Therefore, the current paper aims to summarize and evaluate existing scientific information on outbreaks, relevant pathogens in low moisture foods, and knowledge on indicators, including their contribution to a "clean" environment capable of limiting the spread of pathogens in dry production environments. This paper also outlines the essential elements of a processing environment monitoring program thereby supporting the design and implementation of better programs focusing on the relevant microorganisms. This guidance document is intended to help industry and regulators focus and set up targeted processing environment monitoring programs depending on their purpose, and therefore provide the essential elements needed to improve food safety.Keywords Expand

FOOD RELATED CONTAMINANTS
Mineral Oil Hydrocarbons may unintentionally contaminate food through different routes across food chains and the lifecycle of food contact materials.
Gaps in the knowledge about mineral oil hydrocarbons (MON) still exist despite the recent advances in the research field.
A workshop to identify those gaps was organized by the European Branch of the International Life Science Institute.
Some of these were identified to be:
- the lack of validated and standardized analytical methods for relevant food matrices, and
- gaps in assessing the risk for consumers' health.
The consensus is that the lack of standardized, validated analytical methods able to assure good inter-laboratory reproducibility is the main gap underlining most of the existing difficulties to understand MOH.
In order to conduct adequate substance identification and quantification for input into risk assessment, the need for confirmatory methods that provide a detailed characterization of the unresolved complex mixtures needs to be solved.
The limited number of surveys covering a wide range of foods and enough samples to detect major sources of contamination other than packaging in paperboard also hinders reliable exposure estimation.

In recent years there have been significant advancements in the understanding of mineral oil hydrocarbons (MOH) in foods and their potential risk to health. However, important gaps in knowledge remain, such as the lack of validated and standardized analytical methods for relevant food matrices and gaps in assessing the risk for consumers' health. Scope & approach
A workshop was organized by the European Branch of the International Life Science Institute to identify knowledge gaps in analytical methods, assessment of exposure, hazard characterisation, and risk assessment of MOH. This work captures the outcome of the workshop and builds upon it by combining the perspectives of the participants with an updated review of the literature to provide a roadmap for future management of the topic. Key findings and conclusions
Most participants to the workshop agreed that the key issue underlying many of the knowledge gaps in the field of MOH risk analysis and management is the lack of standardized, validated analytical methods able to assure good inter-laboratory reproducibility and to enable understanding of MOH occurrence in foods. It has been demonstrated that method EN 16995 used for MOH determination in vegetable oils and fats is not reliable below 10 mg/kg of food. There is also a need for confirmatory methods that provide a detailed characterization of the unresolved complex mixture observed from one-dimensional chromatographic methods. This is required to enable adequate substance identification and quantification for input into risk assessment. A major gap in the exposure estimation is the limited number of surveys covering a wide range of foods and enough samples to detect major sources of contamination other than packaging in paperboard. Data on concentration of MOH fractions in human body needed to determine internal exposure estimates is scarce. Data relating concentration in tissues with personal data, lifestyle, food intake and the use of cosmetics are needed to clarify the complex system of distribution of MOSH in the body and to possibly establish relationship between external and internal exposure. Additional toxicological studies to better characterize the hazards of relevant MOH are required for a better human health risk assessment. Keywords Expand

GUT MICROBIOME AND HEALTH
The gut and brain link via various metabolic and signalling pathways, each with the potential to influence mental, brain and cognitive health. Over the past decade, the involvement of the gut microbiota in gut-brain communication has become the focus of increased scientific interest, establishing the microbiota-gut-brain axis as a field of research. There is a growing number of association studies exploring the gut microbiota's possible role in memory, learning, anxiety, stress, neurodevelopmental and neurodegenerative disorders. Consequently, attention is now turning to how the microbiota can become the target of nutritional and therapeutic strategies for improved brain health and well-being. However, while such strategies that target the gut microbiota to influence brain health and function are currently under development with varying levels of success, still very little is yet known about the triggers and mechanisms underlying the gut microbiota's apparent influence on cognitive or brain function and most evidence comes from pre-clinical studies rather than well controlled clinical trials/investigations. Filling the knowledge gaps requires establishing a standardised methodology for human studies, including strong guidance for specific focus areas of the microbiota-gut-brain axis, the need for more extensive biological sample analyses, and identification of relevant biomarkers. Other urgent requirements are new advanced models for in vitro and in vivo studies of relevant mechanisms, and a greater focus on omics technologies with supporting bioinformatics resources (training, tools) to efficiently translate study findings, as well as the identification of relevant targets in study populations. The key to building a validated evidence base rely on increasing knowledge sharing and multi-disciplinary collaborations, along with continued public-private funding support. This will allow microbiota-gut-brain axis research to move to its next phase so we can identify realistic opportunities to modulate the microbiota for better brain health.
