A new study says trace amounts of a weed killer were detected in several popular brands of wine and beer.

The study done by the US Public Interest Research Group says the specific products are contaminated with glyphosate, the main ingredient in the weed killer Roundup, which is a potential health problem because back in 2015, the World Health Organization found glyphosate is a probable carcinogen.

According to the group, of the 20 samples tested, 19 contained glyphosate, and the highest level was found in Sutter Home wine. 

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.

The report acknowledges the levels detected are below limits considered harmful.

Back in 2018, a California jury found Roundup was a major cause of a man’s cancer, and awarded him millions of dollars in damages.

Thousands of other people are now alleging their cancers may have been caused by it.
