evidence: 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. [...] Glyphosate has been found in a variety of oat products, including oat meals and cereals, as well as some lentils and barleys. Some experts believe late season glyphosate spraying — which hastens the drying out process for crops in the field — is the culprit.
