[Public comment] Draft scientific opinion on the risks to human health related to the presence of perfluoroalkyl substances in food
Policy
24 Feb 2020
The European Food Safety Authority is holding consultation for the proposed PFOA+PFOS+PFHxS+PFNA tolerable weekly intake of 8 ng/kg of body weight per week. Parts of the European population exceed this level with fish, fruit, and eggs being the largest sources of exposure. Comment period ends on April 20, 2020.
