Environmental exposure through air and water also seems to play a significant role for PFOS, and even more so for PFOA. Other food-related exposure routes exist, though to a lesser extent, such as drinking water for both PFOS and PFOA and food packaging material (e.g. microwave popcorn bags), and cookware (non-stick coatings) in the case of PFOA.
High exposure to PFOS and PFOA can have a harmful impact on health and can damage the liver, cause developmental and possibly reproductive problems. Certain laboratory experiments on rats have indicated some potential to promote cancer but it is not clear if these results have implications for human health.
The Panel called for further research and data collection on PFOS/PFOA presence in foods and feeding stuffs in order to assess their relative contribution to human dietary exposure.
