Ben and Jerry's announced that they are making changes to their sourcing to eliminate the chemical glyphosate from ingredients they purchase...by 2020. Glyphosate, a main ingredient in the herbicide Roundup, was found to be present in their product (as well as other food products) at very low levels - far below what EPA would cause adverse effects (
EPA has a limit of 2 mg/kg/day vs 1.75 ppb found) and EPA says that the chemical is not likely to be carcinogenic.
In 40CFR180, lists the tolerances for pesticide residues in food including glyphosate (180.364 - table below). EPA's established tolerance for glyphosate in drinking water is 700 parts per billion (ppb).
So 1.75 ppb is pretty darn low, and based upon this EPA limit, a news article (below) determined that a kid would have to eat over 100,000 servings per day to get to this level. And glypshate is common in the environment and as well other foods. A
study found that many cereal grain products had levels ranging from 25 to 1000 ppb - again, all well below EPA limits. It is even
in wine (in a 2016 report, the highest level found was 18.74 ppb).
But people get excited, especially once you link a herbicide to thier food. I think the controversy is good. It forces the science to prove its safety and for the agricultural industry to manage its use. Where we fail is communicating to consumers the minimal risk associated with the amount that was found.
