Study Reveals PFAS Contaminants in U.S. Brews

News Summary

A recent study by RTI International shows that various beers brewed across the U.S., particularly in Michigan, contain PFAS chemicals. The findings raise health concerns as PFAS are linked to serious conditions like cancer. Beers from Kalamazoo and Kent counties exhibited alarming levels of PFOA and PFBS, respectively. With 18% of U.S. breweries located in PFAS-contaminated areas, the Brewers Association urges breweries to monitor water sources and adopt better filtration methods. This highlights the need for increased consumer awareness regarding PFAS in both drinking water and beverages.

Kalamazoo, Michigan – A recent study by RTI International has discovered the presence of PFAS (“forever chemicals”) in beers brewed across several U.S. states, including Michigan. The study raises health concerns regarding the consumption of these beverages, as PFAS compounds are linked to various health problems including cancer and thyroid disorders.

The findings indicate that beers brewed in areas with high levels of PFAS in municipal water systems often contain these harmful chemicals. Some beers tested from Kalamazoo and Kent counties in Michigan showed particularly high concentrations of these compounds. Specifically, one beer from a Kalamazoo County brewery registered an alarming level of PFOA at 8.374 parts per trillion, which exceeds the Environmental Protection Agency (EPA) Maximum Contaminant Level (MCL) of 4 parts per trillion.

Of the 23 beers examined in the study—primarily consisting of plain lagers and ales—PFAS compounds were detected in 11 of the 19 beers sampled. A total of 13 out of 15 beers showed contamination when multiple cans were tested.

Breweries’ Response to PFAS Contamination

In response to the findings, Chris Andrus, co-owner of Mitten Brewing Company, noted that while consumers should remain informed, there is no need for excessive concern. He advocates for moderate alcohol consumption. Mitten Brewing Company implements carbon filtration in its water supply to reduce contamination from PFAS and other substances.

Environmental concerns in Kalamazoo County are attributed to industrial processes that have contaminated local water systems and the Kalamazoo River. Also, a Kent County beer was noted for having the highest concentration of PFBS, linked to the former Wolverine Worldwide facility which utilized PFAS in its products.

Nationwide Context of PFAS in Brewing

Alarmingly, 18% of U.S. breweries are located in areas where PFAS have been detected in municipal water. The Brewers Association has recommended that breweries monitor their water sources for PFAS levels. They also suggest the adoption of advanced filtration methods, such as reverse osmosis, to mitigate potential health risks associated with PFAS ingestion.

Health Implications of PFAS Exposure

The long-term implications of PFAS exposure are of significant concern to health experts. Various studies have established links between these chemicals and serious health issues, including increased cancer risks, liver complications, and thyroid disorders. As a result, the new study calls for heightened awareness among consumers and policymakers alike regarding PFAS exposure limitations.

Research reveals that international beers sourced from countries like Mexico and the Netherlands exhibited lower levels of PFAS contaminants compared to domestic brands. This finding underscores the necessity for breweries to implement strict water filtration systems to curb PFAS contamination in their products.

Consumer Guidelines for Safe Beer Consumption

For consumers, it is advisable to check annual municipal water quality reports to make informed choices regarding PFAS exposure in drinking water and beer. Additionally, they should inquire about the water filtration systems utilized by breweries to understand the PFAS levels present in their products.

As the community grapples with the implications of the study, it highlights the urgent need for transparency and safety measures in the brewing industry to safeguard public health.
