RDM Express Inc. – FDA Warning Letter, Mar 10, 2026

RDM Express Inc., based in San Francisco, received an FDA Warning Letter on September 11, 2026, following facility inspections conducted between February 18 and March 10, 2026. The FDA determined that the company’s ready-to-eat fermented cabbage, pickles, and kvas products were prepared under unsanitary conditions and were significantly misbranded, violating the Current Good Manufacturing Practice, Hazard Analysis, and Risk-Based Preventive Controls for Human Food regulation (21 CFR Part 117) and federal labeling requirements. Primary safety violations included a failure to identify and control hazards such as Listeria monocytogenes and viruses associated with raw ingredients like cranberries. The FDA noted that the firm"s reliance on pH levels as a sole safety measure was scientifically inadequate for controlling acid-tolerant pathogens. Additionally, the company lacked an environmental monitoring program, maintained incomplete sanitation logs, and failed to follow consistent equipment calibration procedures. Labeling issues across several product lines involved missing ingredient names, incorrect nutrition facts, and a failure to provide mandatory information in both English and Russian on bilingual packaging. RDM Express Inc. must submit a written response within 15 working days outlining specific corrective actions, providing documentation of these changes, and explaining how they will prevent future occurrences to avoid potential legal action, including product seizures or injunctions.
