Which agency sets standards for manufacturers of products claiming to kill germs?

The Environmental Protection Agency (EPA) is responsible for setting standards for products that make claims about their ability to kill germs. The EPA regulates disinfectants and sanitizers, ensuring they meet specific safety and effectiveness standards before they can be marketed to the public. This involves evaluating the claims made by manufacturers and ensuring that the products are safe for humans and the environment when used as directed.

The Occupational Safety and Health Administration (OSHA) focuses on workplace safety and health regulations, rather than product standards for germicidal claims. The World Health Organization (WHO) provides international public health guidance but does not set standards for product manufacturing. The Centers for Disease Control and Prevention (CDC) offers health recommendations and guidelines but does not regulate products; instead, it relies on the standards set by agencies like the EPA. Thus, the correct answer emphasizes the EPA's role in ensuring the safety and efficacy of germ-killing products.
