An effective disinfection program is an essential component of a pharmaceutical/biopharmaceutical manufacturer’s contamination control strategy. A good disinfection program can help prevent microbial or viral contamination of the manufactured product, further ensuring product safety for patients. The term disinfection is often used interchangeably with cleaning, but the purpose of disinfection is quite different from that of cleaning. Disinfection of a surface will result in inactivation of infectious agents such as bacteria, fungi, and viruses, whereas cleaning a surface removes soil, debris, and other residues.
