Personnel and materials moved freely between areas, increasing cross-contamination risk. The firm's response, detailing HEPA-filtered hoods and cleaning with (b)(4), was deemed insufficient as cleaning cannot substitute for proper segregation, and no scientific justification for using (b)(4) to inactivate beta-lactam rings was provided. The FDA emphasized that no safe level of penicillin contamination exists due to severe allergenic reactions.
2.  **Failure to accurately transfer expiry dates:** An internal audit revealed 186 instances where the firm inaccurately transferred manufacturer-assigned expiry/retest dates to customers, extending them by up to (b)(
