Florida Attorney General James Uthmeier has issued a civil subpoena to General Mills, Inc. and General Mills Operations, LLC as part of an investigation into the supply chain of products containing potassium bromate sold in Florida under the Florida Deceptive and Unfair Trade Practices Act.

According to the Office of the Attorney General, the investigation is examining the presence of potassium bromate in products sold throughout the state, disclosures provided to purchasers, and research related to the ingredient's potential health effects.

Potassium bromate is used as a flour improver and dough conditioner in certain bakery flours. The World Health Organization’s International Agency for Research on Cancer classifies the compound as "possibly carcinogenic to humans." The ingredient has been banned as a food additive in the European Union, Canada, China, India, Brazil, Argentina, South Korea, Peru, and several other countries, according to the Attorney General's office.

The subpoena seeks documents related to General Mills products containing potassium bromate that were sold in Florida, including Pillsbury Potentate High Gluten Flour, Pillsbury Best Bakers Patent Flour, Gold Medal All Aces Bakery Flour, and Gold Medal Superlative Bakers Flour packaged in 50-pound bags.

Investigators are also requesting records identifying the company's largest Florida purchasers of those products from 2023 through 2026, disclosures provided to purchasers of bromated products or foods made from them, research concerning potassium bromate and its potential effects on human safety, and sales of the products to Florida pre-kindergarten through grade 12 schools.

Attorney General Uthmeier said the investigation is intended to provide greater transparency for Florida consumers and examine the supply chain of products containing potassium bromate sold within the state.
