This NebGuide lists the current withdrawal times for medications used in beef cattle.

Using proper livestock medications is very important. Proper use not only ensures maximal benefits from the medication but minimizes the chances of an unwanted residue. The National Cattlemen's Beef Association has worked hard to develop a premiere quality assurance program. In conjunction with other national and state beef and veterinary associations, the Beef Quality Assurance program now extends to almost every state in the nation. As a result, the safety and quality of beef has never been better. The outstanding record includes having an extremely low rate of residue violations.

Livestock medications may be categorized as follows: 1) feed additives and 2) medications used on individual animals.
