“fvlicrobiology Topics” discusses various topics in microbiology of practical use in validation and compliance.
We intend this column to be a useful resource for dai Iy work applications.
Reader comments, questions, and suggestions a.reneeded to help us fulfi!1 our objective far this column.
The following key points are discussed in this article:

• Recommendations for the selection ofsample sites to be used in the qualification program are provided. These recommendations are directed at providing data to allowcreation of a program useful in determination ofthe state ofcontrol ofthe facility
• The frequency ofsampling during a qualification study ofthis type should minimally be at least the
rate ofthe eventual routine monitoring program for each area
