What agency is responsible for regulating liquid chemical disinfectants for medical devices?

The correct answer is the Environmental Protection Agency (EPA). The EPA is specifically tasked with regulating the use of various chemical substances, including liquid chemical disinfectants used for medical devices. Their role involves ensuring that these disinfectants are safe and effective for their intended use, protecting both public health and the environment.

In contrast, the Food and Drug Administration (FDA) primarily oversees the safety and efficacy of medical devices themselves, rather than the disinfectants used to clean them. The Centers for Disease Control and Prevention (CDC) provides guidelines and recommendations related to infection control practices but does not have regulatory authority over disinfectants. The National Institutes of Health (NIH) focuses on biomedical research and does not engage in the regulation of disinfectants or medical devices. Thus, the EPA is the appropriate agency when it comes to the regulation of liquid chemical disinfectants specifically.
