U.S. FDA Issues Warning Letter to Tom's of Maine for CGMP Violations

The violations primarily involved microbiological contamination in water and finished toothpaste products, inadequate water system controls, and poor building maintenance in facilities used for drug production.

On November 19, 2024, the U.S. Food and Drug Administration (FDA) issued a warning letter to Colgate-Palmolive regarding significant violations of Current Good Manufacturing Practice (CGMP) regulations at its subsidiary Tom's of Maine's drug manufacturing facility in Maine. The issues were identified during an FDA inspection conducted in May 2024.

Key violations highlighted in the warning letter include:

Microbiological Contamination: The FDA found Pseudomonas aeruginosa and Ralstonia insidiosa in water samples, and Paracoccus yeei in finished OTC toothpaste products. The company failed to adequately investigate the impact of these contaminants on product quality and safety.
Inadequate Water System: The company did not adequately qualify its water system used for equipment cleaning and OTC drug product formulation. The Installation Qualification/Operational Qualification (IQ/OQ) lacked essential analyses for total organic carbon and conductivity, crucial for meeting product specifications. The absence of gram-negative microorganism analysis further raised safety concerns.
Building Maintenance Deficiencies: Inspections revealed black mold-like substances existing near both product-contact equipment and uneven surfaces in manufacturing areas. This finding indicates the company’s failure to maintain the facility in good repair as required by CGMP regulations.

The FDA has instructed Colgate-Palmolive/Tom’s of Maine to take immediate corrective actions, including a thorough assessment of manufacturing operations, detailed risk assessments, comprehensive investigations into contaminated batches, establishment of appropriate batch release specifications, submission of all necessary testing methods and results, submission of a remediation plan for the water system, etc.
