"Although levels of older “forever” chemicals have declined in many foods over the past 20 years, a new study shows that drinking water, seafood, eggs, and brown rice remain significant sources of PFAS exposure for adults.

For years, food has been seen as a key way people are exposed to PFAS, a group of long-lasting chemicals found in everything from industrial materials to everyday consumer products. These “forever chemicals” are known to linger in the environment and have been linked to serious health risks. But there’s encouraging news.

A new study from researchers at the Boston University School of Public Health (BUSPH) finds that PFAS exposure through food has actually declined among adults over the past 20 years. However, the study also highlights that drinking water is still a significant source of PFAS exposure."
