King Farms – FDA Warning Letter, Jun 19, 2025

The FDA issued a Warning Letter to King Farm following an inspection from June 16-19, 2025, prompted by at least 30 horse deaths and one potential goat death linked to the company"s animal food products. The inspection revealed that King Farm"s products, including King’s All Stock Feed and King’s Horse Feed 12-6 Blend, were adulterated with excessive levels of fumonisin, ranging from 18 to 36.1 parts per million (ppm), significantly exceeding the FDA’s recommended limit of 5 ppm for equids. Violations of the Current Good Manufacturing Practice (CGMP) and preventive controls for animal food (21 CFR Part 507) were identified. Specifically, King Farm failed to adequately evaluate raw materials like corn for mycotoxin contamination before use, directly leading to adulterated products. Additionally, the company failed to report this serious health risk to the Reportable Food Registry (RFR) within the required 24 hours, a violation of the FD&C Act. While King Farm initiated some operational changes post-incident, a comprehensive and species-specific mycotoxin evaluation program was not fully established by the inspection"s conclusion. The FDA noted the lack of a formal written response to the inspectional observations (Form FDA 483) and encouraged the company to provide documentation of corrective actions.
