Final answer:
The US EPA does not regulate animal vaccines; this is the responsibility of the United States Department of Agriculture. The EPA does regulate biopesticides, novel microorganisms, and herbicide-resistant plants under the Federal Insecticide, Fungicide, and Rodenticide Act.
Step-by-step explanation:
The product that the US Environmental Protection Agency (EPA) is not involved in regulating is animal vaccines. This is because animal vaccines are regulated by the United States Department of Agriculture.
On the other hand, the EPA does regulate biopesticides, which include substances like pyrethrum, rotenone, and neem oil, as well as plant-incorporated protectants (PIPs) and other bio-derived chemicals.
Pesticides, including those that are organic, must meet standards set by the EPA under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
Moreover, the EPA oversees the regulation of novel microorganisms that are considered safe and pose minimal risk to the environment and workers.
Lastly, the EPA is involved in the regulation of herbicide-resistant plants, which are typically genetically modified crops with added genetic material to resist certain herbicides.
