In a move to provide a means for food and beverage processors to show their products are free of residual glyphosate (an active ingredient in Roundup and other herbicides), The Detox Project has applied and been granted a trademark symbol that processors may use on their labels, provided their products are tested and do not contain glyphosate or AMPA (aminomethylphosphonic acid) residues exceeding the limits of laboratory detection, which is typically between 0.1 and 20 parts per billion (ppb). AMPA is a metabolite of glyphosate.
AMPA is considered a weak organic acid with a phosphoric group and a primary degradation product of glyphosate. Regulators claim that glyphosate and AMPA have similar toxicological profiles, but more research is needed to confirm AMPA’s potential toxic impacts. Meanwhile, the amount of residual glyphosate in a food or beverage, which may be considered toxic, is also open to question, and US regulations typically allow higher levels than those in Europe.
