Microbial load fell within the predefined limit, suggesting contamination was controlled during a single time point.

Microorganism proliferation on dirty equipment in a class D manufacturing facility was managed during a hold time of 96 hours, a bioburden study shows.

The low variability indicated consistent contamination control performance, the author wrote.

While a key part of the cleaning validation process, the dirty-hold time study is “typically overlooked”.

In an environmental monitoring area at the non-sterile facility, samples were
