		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.

		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.
