FDA WARNING_LETTER - Allandale Dairy - March 19, 2026

On June 23, 2026, the U.S. Food and Drug Administration (FDA) issued a warning letter to Allandale Dairy, located in Pierz, Minnesota, following inspections conducted on March 3, 11, and 19, 2026. The dairy is cited for significant violations of the Federal Food, Drug, and Cosmetic Act regarding the sale of adulterated food and the misuse of animal drugs. The primary violation involved the sale of a cow for slaughter that contained sulfadimethoxine residues at 0.116 parts per million, which exceeds the established safety tolerance of 0.1 parts per million. Additionally, the FDA found that the dairy held animals under inadequate conditions by failing to maintain complete treatment records, specifically omitting the conditions treated and the identity of the persons administering medications. Allandale Dairy was also cited for "extralabel" drug use, which refers to using medications in a manner inconsistent with their approved labeling or veterinary prescriptions. Examples included incorrect dosing of sulfadimethoxine based on the animal"s estimated weight and administering flunixin meglumine more frequently than directed. Under federal regulations, these actions render the resulting food products adulterated and the drugs unsafe. The FDA requires Allandale Dairy to submit a written response within 15 working days detailing the specific steps taken to correct these violations and prevent their recurrence. Failure to address these concerns may result in further regulatory or legal action.
