The contributory factors for contamination or cross-contamination could be human, facility, procedure, equipment, or utility. The contamination and cross-contamination could occur at any stage, starting from raw material sources to the packaging of pharmaceutical products.

Contamination or cross-contamination chance in pharmaceutical industry is a major regulatory observation. It may comes from lack of cleaning validation and verification studies and/or inaccurate facility design.
