US PIRG's 2019 investigation into alcohol and pesticide residues tested
Budweiser alongside other major beer brands. The results showed detectable
glyphosate in Budweiser at 27 ppb. Beer is of particular concern because
barley and rice — the primary grain inputs — are frequently sprayed with
glyphosate as a pre-harvest desiccant.
