This NebGuide promotes exercising caution while working with livestock medications.

Veterinary drugs, including antibiotics, antiparasite medications and vaccines, play an important role in the control and prevention of disease in all livestock. However, there is risk when working with animals and animal medicines. The United States Department of Agriculture (USDA), Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) have strict rules regulating the prescription, distribution and use of animal medications and chemicals. Regulations on how a drug is stored, administered, and disposed of ensure product safety to the producer, animal, consumer and environment.
