Public Health Registration
EPA-Public Health Registration applies to antimicrobial products intended to control pathogens that could be detrimental to public health. In order to obtain the first EPA public health registration for a touch surface material, antimicrobial copper alloys had to demonstrate efficacy under rigorous, EPA-approved test protocols carried out in an EPA approved and audited independent third party commercial testing laboratory. Three test protocols were developed to test antimicrobial copper alloys ability to kill bacteria* that cause infections. A description of the testing is provided below.
Required Testing for Regulatory Approval
The three EPA approved Good Laboratory Practice (GLP) test protocols used to register antimicrobial copper with public health claims are:
1. Efficacy as a Sanitizer - which measures viable bacterial count after two hours.
2. Residual Self-Sanitizing Activity - which measures bacterial count before and after six wet and dry wear cycles during which bacteria are added in a standard wear apparatus.
3. Continuous Reduction of Bacterial Contaminants - which measures bacteria after inoculating an alloy surface eight times in a 24-hour period without intermediate cleaning or wiping
