Testing Finds Glyphosate in Two Popular Oat Milks

The widely used herbicide was detected in 2 of 13 oat milk brands tested.

Two out of 13 popular brands of oat milk had detectable levels of the controversial herbicide glyphosate, according to a new report from Mamavation.

Partnering with EHN.org, the environmental wellness blog and community had the oat milks tested by a U.S.-Environmental-Protection-Agency-certified lab for glyphosate and heavy metals. They found traces of glyphosate and arsenic in MALK Organic Oat Milk at 12 parts per billion, and glyphosate in Silk Extra Creamy Oatmilk at 14 parts per billion.

“Oat milk is consumed by many people as a drink alternative that goes into coffee, cereals, baked goods, and other foods,” Linda Birnbaum, scientist emeritus and former director of the National Institute of Environmental Health Sciences and National Toxicology Program, told Mamavation. “One exposure would be fine, but daily exposure is concerning. “

Glyphosate is the most widely-used herbicide in the world and linked to number of human health problems including cancer, neurological diseases, endocrine disruption and birth defects. Arsenic is linked to cancer, cardiovascular disease and developmental impacts to children.
