A chemical known as PFAS, which is found in industrial and household products, is polluting lakes and rivers in the US, and accumulating at high levels in freshwater fish, posing a health risk to those who rely on fishing for their diets. There are currently no federal standards for safe consumption, and the regulations vary significantly among states. PFAS is more detrimental than mercury, another contaminant found in fish, and a single serving of the most contaminated fish can be the equivalent of drinking water containing high levels of PFAS for a month.
