Aseptic Process Challenges: The Threat of Underperforming Disinfectants for cGMP Applications: Poster Presented at PDA Microbiology Conference 2025.

Abstract

This poster evaluates the Disinfectant Efficacy Test (DET) of various sporicidal solutions and chemistries used in an aseptic manufacturing site for parenteral and ophthalmic products, guided by USP <1072>. The assessment spans three different timeframes: the initial DET evaluation and two Corrective and Preventive Actions (CAPAs) prompted by sterility failures years later. It includes an analysis of different bacterial spore formers and the impact of disinfectant supply constraints on the market.The poster discusses the risks associated with the use of disinfectants that do not meet performance standards, emphasizing their potential threat to commercial operations. Additionally, it addresses the challenge posed by microorganisms with higher natural resistance, even when their isolation frequency is low in the environmental monitoring (EM) program.
