Activity Overview

Ongoing

- Update on Risk-Benefit Assessment of Foods: Approaches to Facilitate Application

An expert group on risk-benefits assessment of foods explores the reasons for limited application and seek practical solutions to increase the utility of this methodology in foods.

Start: Sep 2021 - End: Dec 2024

- Prioritisation of Natural Toxins for Risk Management Action

The Expert Group on the prioritisation of natural toxins for risk management action establishes a framework to prioritise natural toxins in foods following a riskbased approach. Based on the evidence and scale of risk to consumers, the framework will enable the differentiation between mycotoxins or phytotoxins where risk management action is both warranted and likely to be effective based on available evidence

Start date: Nov 2022 - End date: Nov 2025

- Food contaminant definitions

An expert group on food contaminant definitions explores existing definitions, their clarity and consistency. This activity un-picks the perceptual underpinning of those different definitions, the key parameters that drive them and the different stakeholders who use them and it identifies the possibility to consolidate a global definition of ‘food contaminant’.

Start date: Feb 2023 - End date: Feb 2024

Upcoming

- Early Career Scientist Seminar

A seminar for Early Career Scientists will take place in Q1 2025. Find more info here.

Update on Risk-Benefit Assessment of foods: approaches to facilitate application

Background and Objectives

All foods contain chemical and biological impurities some of which may be viewed as contaminants of toxicological or microbiological relevance, depending on the definition used. Classical risk assessment does not reconcile the benefit to health of the food against the potential effects of the contaminants or the impact of mitigation measures that may be applied to reduce contaminants. A contaminant-centric view of a food can result in an incomplete understanding of the net health benefits of food by groups such as policy makers.

As such, methods for the comparison between benefits and risks have been developed, including the publication of guidance materials. Despite the availability of guidance, there have been a limited number of examples of risk-benefit analysis being used as an input for the risk management of foods by food safety agencies.

Output

This activity will review the evolution and application of risk-benefit assessment since its infancy, and thereby understand:

- Why risk-benefit assessment has not been more widely applied by food safety agencies in Europe?
- What are the available applications of RBA since the publication of guidance and what are the lessons learned?
- Whether existing guidance can be amended to improve applicability?
- The above learnings will be tested via a limited number of worked examples and summarized in a peer-reviewed publication.

Approaches to Facilitiate Application Prioritisation of Natural Toxins for Risk Management

Background and objectives

In its simplest form, risk is the product of hazard (i.e., toxic potency of a chemical) and exposure (or dose). ‘’Hazard-based’’ decision-making is based solely on hazard without any consideration of exposure. The development of mitigation strategies should prioritize mycotoxins that regularly occur at undesirable levels in commonly consumed commodities, wherein both the toxicological profiles and effectiveness of mitigation are understood with a reasonable degree of certainty. The ultimate goal of mycotoxin mitigation is to prevent adverse health effects caused by foodborne exposure to mycotoxins while reserving nutritional and organoleptic quality of food. Based on the evidence and scale of risk to consumers, and the potential for risk mitigation, the framework will enable the differentiation between mycotoxins or phytotoxins where risk management action is both warranted and likely to be effective based on available evidence. Through case-studies, this framework will also highlight potential knowledge gaps.

Output

This activity will establish a framework for the prioritization of natural toxins found in food following a risk-based approach (Decision Tree). Based on the evidence and scale of risk to consumers, and the potential for risk mitigation, the framework will enable the differentiation between mycotoxins or phytotoxins where risk management action is both warranted and likely to be effective based on available evidence. Through case-studies, this framework will also highlight potential knowledge gaps.

Food Contaminants Definitions

Background and Objectives

Chemical contaminants are a major focus of risk assessment and management, however there is no common definition of what constitutes a ‘food contaminant’. It is not clear which substances fall into scope of being considered a ‘food contaminant’, and it is not clear what criteria define a substance to be a ‘food contaminant’. As such there is confusion between stakeholders when there is any communication on the subject of ‘food contaminant’. As communication between stakeholders about food contaminants is frequent, there is a pressing need to explore understanding amongst stakeholders and seek clarity on how the term should be defined and therefore used. Activity will un pick the perceptual underpinning of those different definitions, the key parameters that drive them and the different stakeholders that use them. Moreover, identify if it is possible to consolidate a global definition of ‘food contaminant’ and explore the value of using the above understanding as a communication tool with food chain stakeholders.

Output

Overall, the research would provide a comprehensive understanding of the diverse definitions of ‘food contaminant’ among stakeholders, examine the factors influencing these definitions, evaluate the possibility of achieving a global definition, and highlight the potential benefits of using this understanding as a communication tool with stakeholders in the food chain.

The "totality" of the human exposure is conceived to encompass life-associated endogenous and exogenous aggregate exposures. Process-related contaminants (PRCs) are not only formed in foods by heat processing, but also occur endogenously in the organism as physiological components of energy metabolism, potentially also generated by the human microbiome. To arrive at a comprehensive risk assessment, it is necessary to understand the contribution of in vivo background occurrence as compared to the ingestion from exogenous sources. Hence, this review provides an overview of the knowledge on the contribution of endogenous exposure to the overall exposure to putative genotoxic food contaminants, namely ethanol, acetaldehyde, formaldehyde, acrylamide, acrolein, α,β-unsaturated alkenals, glycation compounds, N-nitroso compounds, ethylene oxide, furans, 2- and 3-MCPD, and glycidyl esters. The evidence discussed herein allows to conclude that endogenous formation of some contaminants appears to contribute substantially to the exposome. This is of critical importance for risk assessment in the cases where endogenous exposure is suspected to outweigh the exogenous one (e.g. formaldehyde and acrolein).

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.

Scientific abstract Expand Background
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

The "totality" of the human exposure is conceived to encompass life-associated endogenous and exogenous aggregate exposures. Process-related contaminants (PRCs) are not only formed in foods by heat processing, but also occur endogenously in the organism as physiological components of energy metabolism, potentially also generated by the human microbiome. To arrive at a comprehensive risk assessment, it is necessary to understand the contribution of in vivo background occurrence as compared to the ingestion from exogenous sources. Hence, this review provides an overview of the knowledge on the contribution of endogenous exposure to the overall exposure to putative genotoxic food contaminants, namely ethanol, acetaldehyde, formaldehyde, acrylamide, acrolein, α,β-unsaturated alkenals, glycation compounds, N-nitroso compounds, ethylene oxide, furans, 2- and 3-MCPD, and glycidyl esters. The evidence discussed herein allows to conclude that endogenous formation of some contaminants appears to contribute substantially to the exposome. This is of critical importance for risk assessment in the cases where endogenous exposure is suspected to outweigh the exogenous one (e.g. formaldehyde and acrolein).
