Mixtures methodology equips EFSA for multiple chemicals

EFSA has developed a harmonised framework to use across its scientific panels when evaluating the potential “combined effects” of chemical mixtures in food and feed. The approach gives EFSA’s scientists the tools to follow a mixtures approach when needed, which complements the current EU regulatory requirements for assessing single substances.

People, animals and the environment can be exposed to multiple chemicals from a variety of sources. Understanding how combined chemicals behave is complex and the number of combinations is potentially infinite, so EFSA’s Scientific Committee has developed a practical scientific tool for risk assessors that also supports and informs risk managers.

Low public awareness

An EFSA research study from 2018, also published today, shows that overall in the EU awareness of chemical mixtures among the general public is quite low. EFSA has developed a new interactive multimedia tool to help people understand some of the main issues and concepts, such as “combined exposure” and “combined toxicity”.
