Drinking to your health? Weed killer Roundup lurks in many beers and wines

New report finds glyphosate in popular alcoholic beverages

Having a beer or a glass of wine at happy hour or a backyard barbecue shouldn’t include gulping down a potentially hazardous pesticide. But that’s likely the case, according to a new U.S. PIRG report, The study tested 20 different beers, wines and a hard cider. Researchers found the chemical glyphosate, which is the active ingredient in the world’s most popular weed killer, Roundup, in all but one beverage.

Roundup even invaded three of the four organic beers and wines tested — despite strict rules prohibiting makers of those products from using glyphosate-based herbicides in production. The upshot is that, right now in America, even the best-intentioned brewers and vintners struggle to avoid Roundup leaching into their drinks.

This is troubling for numerous reasons. The primary one is that glyphosate poses a health risk. Last year, a California jury concluded that not only was Roundup a “substantial factor” in causing a plaintiff’s terminal cancer but its producer Monsanto also didn’t warn the plaintiff about this risk. (A federal court is currently considering a case over the same issue.)

PIRG’s Roundup in beer and wine report doesn’t suggest that the glyphosate that partygoers are drinking reaches established danger levels. The largest amount of the herbicide discovered in one of the wines was 51.4 parts per billion (ppb) and the beer with the highest total of the pesticide totaled 49.7 ppb. Neither of those numbers meet the Environmental Protection Agency’s risk tolerances for beverages.

That said, at least one previous scientific study found that as little as one part per trillion of glyphosate can stimulate the growth of breast cancer cells and disrupt the endocrine system. What the report raises is that we are finding Roundup in unexpected places.

Glyphosate has infiltrated nearly every type of food tested by the Food and Drug Administration. We know that researchers are finding glyphosate in honeycerealice creamrain water and now beverages. What we don’t know is what the cumulative effects all of this glyphosate has on a person over a lifetime.

Still, even if downing a couple of glasses of Roundup-tainted wine or chomping down on a bowl of glyphosate-infused cereal isn’t definitively dangerous by itself, and even when we don’t know the risks of consuming this much glyphosate over a lifetime, consumers still deserve transparency.

The public has a right to know what exists in everyday products. Without that knowledge, consumers are prevented from making informed decisions about what they want to eat and drink.

If we’re truly seeking to protect the well-being of people wanting a drink or two, more should be done. Sadly, the government isn’t even conducting basic testing. Two years ago, the U.S. Department of Agriculture dropped plans to examine glyphosate in food. That would have been a good first step, and it needs to be done. Unless research proves glyphosate’s safety, we need a more direct approach: The pesticide shouldn’t be used in the United States.

Until then, it will be hard to offer a full-throated “bottoms up” to your buddies, while you’re worrying about what’s actually at the bottom of the bottle.
