Look beyond repeated disinfection
VanTsteri’s technical article examines recurring mold findings in pharmaceutical clean areas. It focuses on how treatment evaluation and environmental monitoring can influence the interpretation of results.
Review sampling and recovery
The article identifies disinfectant carryover and a restricted sampling plan as possible reasons for overly favorable results. It recommends considering suitable neutralization and sampling locations that reflect the actual contamination risks.
Combine different evidence
Routine environmental counts and biological indicators address different questions. The source recommends combining treatment evaluation with monitoring under actual operating conditions. This article is a technical discussion, not a quantified customer case or a guarantee of mold eradication.
