DO & CO Los Angeles, Inc. (DO & CO) – FDA Warning Letter, Aug 18, 2025

The FDA issued a Warning Letter to DO&CO Aktiengesellschaft/DO&CO, Inc. following inspections of its airline catering facilities in New York and Michigan conducted between June and August 2025. These inspections were follow-ups to 2024 findings regarding widespread sanitation issues. The agency identified serious violations of federal food safety regulations, primarily centered on the failure to implement adequate sanitation and temperature controls. Laboratory testing confirmed the persistent presence of Listeria monocytogenes in production environments and ready-to-eat products across multiple facilities. Genetic analysis linked several of these bacterial strains to human illness, suggesting the pathogen has become resident in the company"s processing areas. Investigators observed numerous hygiene failures, such as employees handling trash or raw meat before touching ready-to-eat food without washing hands or changing gloves. Additionally, the company failed to consistently monitor food storage temperatures and used inaccurate thermometers, increasing the risk of bacterial growth. While DO&CO has submitted several status updates regarding its corrective actions, the FDA noted that the company has not yet proven it has eradicated the source of contamination or fully implemented necessary safety protocols. The FDA requires DO&CO to respond within 15 working days with a detailed plan to address these violations and prevent their recurrence. Failure to comply may lead to legal actions, including product seizures or injunctions.
