In veterinary medicine, Cyromazine (CAS NO.66215-27-8) is used as a ectoparasiticide. Also it can be used as an insecticide and an acaricide.

The Food Safety and Inspection Service (FSIS) of the United States Department of Agriculture (USDA) provides a test method for analyzing cyromazine and Melamine in animal tissues in its Chemistry Laboratory Guidebook which "contains test methods used by FSIS Laboratories to support the Agency's inspection program, ensuring that meat, poultry, and egg products are safe, wholesome and accurately labeled." In 1999, in a proposed rule published in the Federal Register regarding cyromazine residue, the United States Environmental Protection Agency (EPA) proposed "remov[ing] Melamine, a metabolite of cyromazine from the tolerance expression since it is no longer considered a residue of concern."
