Final answer:
Sanitizers are registered with the Environmental Protection Agency (EPA) to ensure their safety and effectiveness.
Step-by-step explanation:
Sanitizers are indeed registered with the Environmental Protection Agency (EPA). This agency is responsible for protecting human health and the environment, which includes regulating compounds and substances such as sanitizers and pesticides that may potentially affect public health. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), sanitizers must be registered with the EPA to ensure they are safe and effective for use.
The EPA's oversight extends to ensuring appropriate water quality standards are met, as well as regulating the use of various chemicals. According to Human Biology by CK-12, soaps and sanitizers fall under the broader category of disinfectants. It's important to note that not all products used for cleaning and disinfection are registered as such, but those claiming to sanitize or kill germs typically need EPA registration.
