Taco Bell Beef Taco Supreme
At a glance
Summary
Taco Bell Beef Taco Supreme tested at 13.70 ppb glyphosate in Moms Across America's 2024 fast-food investigation — a low residue for chain-restaurant food. Glyphosate (Roundup's active ingredient) is a WHO IARC Group 2A probable human carcinogen linked to non-Hodgkin's lymphoma, endocrine disruption, kidney and liver impairment, and microbiome disturbance. Likely sources: conventional corn/wheat in the shell or tortilla plus seed oils from glyphosate-treated crops.
