March 25, 2025 — The U.S. Food and Drug Administration (FDA) added eight Chinese clam exporters to a recent import alert due to contamination with per- and polyfluoroalkyl substances (PFAS).
The FDA said that products from the eight manufacturers and processors had “detected elevated levels of PFAS, notably perfluorooctanoic acid (PFOA), in samples of clams.”
December 20, 2024 — The FDA refused entry of three shipments of canned clams into the U.S. after finding high concentrations of perfluorooctanoic acid (PFOA), a type of polyfluoroalkyl substance (PFAS).
According to testing from the FDA, canned clams from Tri-Union/Chicken of the Sea, Crown Prince, and Kawasho Foods’ Geisha brand showed high levels of PFOA. In FDA testing of 12 processed clam samples in September and October, it found the three highest concentrations of PFOA were 6.02 parts per billion (ppb) in the sample of Geisha clams, 6.59 ppb in Crown Prince clams, and 25.2 ppb in Tri-Union/Chicken of the Sea clams.
