FDA to re‑examine safety of BHA food preservative

Feb 10 Breaking Twin Cities 1 source 4 relevant data

The U.S. Food and Drug Administration is reopening its safety review of butylated hydroxyanisole (BHA), a synthetic preservative used for decades in a wide range of snack foods, cereals and packaged products found on Twin Cities store shelves. The agency says it will take a fresh look at toxicology and cancer data that has piled up since BHA was first approved, responding to petitions from health advocates who point to animal studies that flagged tumor risks at high doses. The review could lead FDA to tighten limits, require new warning labels, or in an extreme case revoke BHA’s "generally recognized as safe" (GRAS) status, forcing manufacturers to reformulate products sold in Minneapolis–Saint Paul groceries, corner stores, and school vending machines. Food scientists quoted in the piece stress that current exposure levels are far below doses used in lab studies, while watchdog groups argue that with so many alternative preservatives available, regulators should err on the side of eliminating avoidable chemical risks. On social media, dietitians and consumer advocates are already circulating brand lists and label-reading guides, urging metro shoppers to watch for BHA on ingredients panels while the federal review plays out over the coming months.

📌 Key Facts

The FDA has formally initiated a new safety review of butylated hydroxyanisole (BHA), a widely used food preservative.
Advocacy groups petitioned FDA to revisit BHA’s "generally recognized as safe" status, citing animal studies that found tumors at high-dose exposures.
Any change in BHA’s regulatory status could force reformulation or relabeling of numerous packaged foods sold in Minneapolis–Saint Paul supermarkets and convenience stores.

📊 Relevant Data

The National Toxicology Program classifies butylated hydroxyanisole (BHA) as reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

Animal studies have shown that dietary exposure to BHA causes forestomach papillomas and squamous cell carcinomas in rodents (rats, mice, and hamsters) with dose and temporal relationships.

The mean daily intake of BHA varies from about 0.002 mg/kg/day to 0.3 mg/kg/day by consumer ages, regions and estimate methods.
