Evidence and sources

IARC classifies BHA as possibly carcinogenic to humans (Group 2B), and the US National Toxicology Program lists it as reasonably anticipated to be a human carcinogen. Both are based on tumors in the forestomach of rats and hamsters fed high doses. FDA and EFSA permit BHA within set limits; in February 2026 FDA began reassessing whether it is still safe.

People don't have a forestomach, and how well these high-dose findings apply at food-use levels is debated. The amount in this product isn't declared.
