Experts Warn of Toxic Carcinogens Found in Widely Consumed Beer Brands
Health Alert: ‘Forever Chemicals’ Found in Popular Beers, Posing Health Risks
A recent study has detected PFAS (per- and polyfluoroalkyl substances), harmful "forever chemicals" linked to cancer and other health issues, in popular beers across North America and Europe. These chemicals, which resist environmental breakdown, were found in 95% of tested beers, including those from the U.S., Mexico, and the Netherlands. The study highlights urgent concerns for brewers and consumers alike.
Key Findings:
- Widespread Contamination: PFAS were detected in 95% of 23 tested beers, including PFOS and PFOA, which exceeded EPA safety limits. Samples came from U.S. states like North Carolina, Michigan, and California, as well as international sources.
- Sources of Contamination: PFAS likely enter beer through contaminated water, brewing ingredients (grains, hops), and packaging materials (cans, bottles). Water, a primary ingredient, often retains PFAS despite standard filtration.
- Health Risks: Linked to infertility, hormonal disruptions, high cholesterol, and cancers (kidney, ovarian), PFAS accumulate in the body and environment, earning the "forever chemicals" nickname.
Study Insights:
- Regional Differences: Beers from areas with known PFAS-contaminated water (e.g., North Carolina) showed higher chemical levels. Smaller breweries had more PFAS than larger ones, possibly due to less advanced filtration.
- Global Concern: Researchers urge expanded testing in major brewing nations like Germany and China, emphasizing the need for global awareness.
Recommendations:
- For Breweries: Invest in advanced water filtration systems to remove PFAS and regularly test ingredients and water sources.
- For Consumers: Choose beers from breweries that test for PFAS or use filtered water. Stay informed about local water quality.

The Bigger Picture:
PFAS, used since the 1940s in products like non-stick cookware and food packaging, persist in the environment. Their stability and chemical resemblance to fatty acids allow them to disrupt biological processes. As the EPA tightens regulations, breweries must prioritize removing these toxins to safeguard public health.
In short: PFAS in beer is a pressing health issue. Proactive measures from brewers and informed choices by consumers are critical to reducing exposure.
