"The U.S. Food and Drug Administration (FDA) has shared results of sampling and testing for per- and polyfluoroalkyl substances (PFAS) in foodstuffs collected in 2024 under the Total Diet Study (TDS). One or more PFAS were detected in 39 (7.2 percent) of 542 samples.

Foods that contained trace amounts of PFAS included cod, shrimp, clams, salmon, tilapia, catfish, pepperoni, beef steak, ground beef, chicken breast, half and half, whole milk, skim milk, and kale. Trace amounts of PFAS refer to levels that fall below the limits of quantification (LOQ) but above method detection limits (MDL) in FDA’s PFAS testing method."
