Safecor Health, LLC, a drug manufacturer and repackager in Woburn, Massachusetts, was cited for significant Current Good Manufacturing Practice (CGMP) violations that rendered its drug products adulterated. During a March 2023 inspection, FDA investigators found inadequate line clearance procedures on the company's blister packaging equipment, with multiple capsules and tablets from different drugs visibly present on and under the machinery despite documented clearance records, creating a substantial risk of dangerous drug product mix-ups. The firm failed to implement adequate controls to prevent cross-contamination and did not properly inspect packaging facilities before use to ensure removal of materials from previous operations, as required under 21 CFR 211.130(e).
