A new study reveals that popular beers in the U.S. contain per- and polyfluoroalkyl substances (PFAS), known as 'forever chemicals', linked to health risks such as cancer and reproductive problems. Researchers at RTI International tested 23 beers, finding that most contained PFAS, with some exceeding safety limits established by the EPA. Water, comprising over 90% of beer, is the primary source of PFAS contamination, especially in craft breweries using municipal water from areas with known contamination.
A study found that many popular beers in the U.S. contain per- and polyfluoroalkyl substances (PFAS), linked to health issues like cancer and reproductive problems.
PFAS are human-made chemicals used in products like food wrappers and firefighting foam, and referred to as 'forever chemicals' due to their persistence in the environment.
PFAS were detected in most of the 23 beers tested, with four exceeding the new EPA-set safety limits for water, emphasizing the importance of water sources in brewing.
One beer from North Carolina had a PFOS level exceeding EPA's drinking water safety limits, revealing the potential contamination in beers brewed with municipal tap water.
