Until about ten years ago, many of the processes used by the tissue industry were based more on trial and error than on thorough validation science. The process of screening for viruses prior to processing the tissue has been done well and in a highly controlled manner. As a result most of the contamination issues in the tissue industry have not been related to viruses and more related to other microorganisms (primarily bacteria) either from the donor or from internal handling and/or processing procedures.

Barriers such as surgical gowns, gloves and drapes are meant to protect professionals from HIV, Hepatitis, and other pathogens that are transmitted through blood and other body fluids.
