Summary

Starbucks Impossible Breakfast Sandwich tested at 87.83 ppb glyphosate in Moms Across America's 2024 fast-food investigation — a moderate 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. Conventional wheat in the ciabatta plus the Impossible patty's GMO soy base (soy is one of the most heavily glyphosate-treated U.S. crops).

Contaminants 1

Source: Independent third-party laboratory testing

Glyphosate
87.83 ppb
Moderate

Detected at a moderate level — a meaningful fraction of health-based exposure limits. Worth factoring in if this product is used regularly. Glyphosate is classified by the WHO IARC as a probable human carcinogen (Group 2A) and is linked in observational research to non-Hodgkin's lymphoma, endocrine disruption, and microbiome disturbance. Entry route is most likely pre-harvest glyphosate desiccation of the wheat or grain ingredient.

Tested at 87.83 ppb glyphosate residue — moderate for a chain-restaurant prepared food.
