The European Food Safety Authority (EFSA) has reduced the safe level of trifluoroacetic acid (TFA) in the diet based on new scientific evidence. TFA is a chemical that can form when per- and polyfluoroalkyl substances (PFAS) break down, including from certain active substances in pesticides. As a result, TFA can end up in groundwater, soil and food crops.
EFSA’s experts lowered the acceptable daily intake (ADI) to 0.014 milligrams per kilogram of bodyweight per day, down from the previous value of 0.05. The new ADI is about 3.5 times lower than the previous one. They also set a new acute reference dose of 0.07 milligrams per kilogram of body weight.
