Report: Ban Roundup

Glyphosate pesticide in beer and wine

Test Results and Future Solutions
Released by: CALPIRG Education Fund

To explore how much Roundup we’re drinking, U.S. PIRG tested beer and wine for glyphosate/Roundup. As we’ve confirmed in this study, Roundup is found in beer and wine. This confirms past studies on the topic, which found that glyphosate is found in almost all adult beverages. For example, in 2016, beer testing in Germany also revealed residues of glyphosate in every single sample tested, even in independent beers. After that study was released, German brewers managed to severely limit the amount of glyphosate used in brewing, and saw marked improvement in a 2017 follow-up study. A study from 2018 in Latvia came to similar conclusions as the original German study, finding glyphosate in all products tested.

We tested 15 products: Five wines and 10 beers. The wine brands tested included Beringer, Barefoot and Sutter Home. Beer brands tested included Budweiser, Coors, Miller Lite, Sam Adams, Samuel Smith Organic and New Belgium.

Low levels of glyphosate can be problematic

While these levels of glyphosate are below EPA risk tolerances for beverages, it is possible that even low levels of glyphosate can be problematic. For example, in one study, scientists found that 1 part per trillion of glyphosate has the potential to stimulate the growth of breast cancer cells and disrupt the endocrine system.
Our recommendation

Based on our findings, glyphosate is found in most beers and wine sold in the U.S. Due to glyphosate’s many health risks and its ubiquitous nature in our food, water and alcohol, the use of glyphosate in the U.S. should be banned unless and until it can be proven safe.
