While most PFAS-treated food packaging is in use for a short time, the chemicals do not break down. Once they are landfilled, incinerated or composted, PFAS chemicals may be able to make their way back into the water and food supply. FDA issued an update in August 2021 on its ongoing sampling and testing efforts designed to better understand the occurrence of PFAS in the food supply. FDA's analysis involved foods collected from the Total Diet Study (TDS), which monitors levels of nutrients and contaminants in foods consumed in the U.S. FDA's analyses showed that most TDS samples do not have detectable levels of PFAS, with the exception of a cod sample in the most recent testing and from previous testing, two tilapia, and one ground turkey sample. To better understand occurrence of PFAS in seafood, FDA is conducting a targeted survey of the most commonly consumed seafood in the U.S., including both cod and tilapia.

Nonetheless, 18 major retailers and a number of fast food companies, such as McDonald's, Wendy’s, and Taco Bell, have already decided to reduce or ban the use of PFAS in food containers, giving momentum to the market movement around restricting the use of these chemicals.
