(Meredith) -- A new report published by the public-interest advocacy group U.S. PIRG found that popular wines and beers, including organic ones, contained trace amounts of the controversial weed killer glyphosate (better known as and ingredient in Monsanto's Roundup).
The group tested five popular wines, 13 popular beers and two popular hard ciders and found that 19 of the 20 total contained trace amounts of glyphosate.
U.S. PIRG tested brands including Coors Light, Miller Lite, Budweiser, Corona, Heineken, Guinness, Stella Artois and Samuel Adams.
The group said that while the levels of glyphosate found are not necessarily dangerous, they are still concerning "given the potential health risks." According to the International Agency for Research on Cancer, a branch of the World Health Organization, glyphosate is a probable human carcinogen (cancer-causer).
However, the levels found in the beer and wine are below what the EPA considers a health risk. A spokesperson for a National Trade Association called the Beer Institute told CNN that even in an adult had 140 glasses of wine per day, the weed killer amount wouldn't be enough to be considered a significant health risk.
The wines tested (in order of most amount of glyphosate in parts per billion [ppb] to least amount) included:
- Sutter Home Merlot: 51.4 ppb
- Beringer Founders' Estate Moscato: 42.6 ppb
- Barefoot Cabernet Sauvignon: 36.3 ppb
- Inkarri Malbec (organic): 5.3 ppb
- Frey Natural White (organic): 4.8 ppb
The beers tested (in order of most amount of glyphosate in parts per billion [ppb] to least amount) included:
- Tsingtao: 49.7 ppb
- Coors Light: 31.1 ppb
- Miller Lite: 29.8 ppb
- Budweiser: 27 ppb
- Corona Extra: 25.1 ppb
- Heineken: 20.9 ppb
- Guinness Draught: 20.3 ppb
- Stella Artois: 18.7 ppb
- Sierra Nevada Pale Ale: 11.8 ppb
- New Belgium Fat Tire Amber Ale: 11.2 ppb
- Sam Adams New England IPA: 11 ppb
- Samuel Smith Lager (organic): 5.7 ppb
- Peak IPA (organic): 0 ppb
The hard ciders tested (in order of most amount of glyphosate in parts per billion [ppb] to least amount) included:
- ACE Perry Hard Cider: 14.5 ppb
- Stella Artois Cidre: 9.1 ppb
Of the 20 drinks tested, only the Peak IPA (organic) did not contain any trace amounts of the weed killer.
Three of the four organic drinks contained trace amounts of weed killer, although the amounts were less than in the non-organic drinks.
The report concludes with the recommendation that, unless it can be proved otherwise, glyphosate "should be banned in the U.S. due to its many potential health risks and ubiquitous presence in food, water and alcohol."

The report comes as a federal case brought against Monsanto over Roundup began in federal court in San Francisco Monday. Plaintiff Edwin Hardeman says the Roundup weed killer he sprayed caused his non-Hodgkin lymphoma.
According to USA Today, more than 9,300 people have filed similar lawsuits across the country.
