FDA WARNING_LETTER - Fenwal International, Inc. - September 26, 2019

The inspection revealed significant deviations from current good manufacturing practice (CGMP) requirements in the manufacture of blood-pack units (BPUs) and InterSol (Platelet Additive Solution).

Key violations include inaccurate and incomplete documentation of microbiology laboratory test results. FDA investigators observed discrepancies between recorded microbial plate results and actual microbial growth, including underreporting of CFUs and failure to document total counts. Additionally, changes to bioburden data results were made improperly, violating SOP MA-03-01-013.
