27 Aug 2021 --- Following a survey of per- and polyfluoroalkyl substances (PFAS) in nationally distributed processed foods, the US Food and Drug Administration (FDA) has concluded that there is “no evidence that levels found in samples indicate the need to avoid particular foods.” The FDA released the results of what it says is the first survey of its kind, looking at several processed baby foods, collected from the agency’s Total Diet Study (TDS), which monitors levels of nutrients and contaminants in foods consumed in the US.
