Regulating Antimicrobials

Who regulates antimicrobial pesticides?

Because they are so important for public health, the U.S. Environmental Protection Agency (EPA) regulates antimicrobial pesticides in a unique way.

How does the EPA regulate antimicrobial pesticides?

The EPA regulates antimicrobial pesticides by reviewing the toxicity of the ingredients and the potential for exposure. If the EPA determines that no adverse effects are expected to occur when the product is used according to the label directions, they grant product registration. EPA requires antimicrobial producers to demonstrate the effectiveness of their products with research. They do this because product effectiveness can impact human health, and germs are invisible to the naked eye.
