Chemical Poisons Reduction Act of 2019 or Canyon's Law This bill prohibits the use of sodium fluoroacetate (i.e., Compound 1080) and sodium cyanide in a predator control device. It imposes criminal penalties—a fine, a prison term of up to two years, or both—on a violator. A predator control device is a dispenser, livestock collar, or gas cartridge that propels, releases, or emits sodium fluoroacetate or sodium cyanide for wildlife management or animal control purposes.
