An annual FDA Warning Letter Report is published by the ECA in cooperation with Concept Heidelberg the 2005 report will be issued shortly. The following concentrates on early trends.
As last year already, the paragraph 21 CFR 211.113 "Control of microbiological contamination" is under the top Ten. While this paragraph was listed as number 6 in 2004, it ranked third this time.
What does this paragraph mean? It requires written procedures to prevent microbial contaminations in not sterile and sterile formulations. It also requires the validation of the sterilisation processes.
The FDA warning letter report contains overall 8 citations relative to 21 CFR 211.113. However, a citation can comprise several deficiencies. Therefore, the following detailed evaluation mentions more listed deficiencies than the actual 8 citations:

Further mentioned deficiencies related to unsatisfactory filter validation.
