D) Endangered Species Act (ESA)
Correct Answer: C - FIFRA is the primary federal statute that establishes the framework
for pesticide regulation, requiring all pesticides sold or distributed in the U.S. to be
registered with the EPA. While FFDCA sets tolerances for residues in food, FIFRA

have overlapping jurisdiction in some workplaces, but the specific agricultural
standards for pesticide handler safety are primarily EPA-driven.

the highest level of acute toxicity?
