FDA 483 - Knauber Farm - July 13, 2023

An FDA inspection of Knauber Farm, a dairy farm in Frederic, WI, revealed two significant issues. The firm offered a food-producing animal for interstate commerce that contained a violative drug residue of sulfadimethoxine. Additionally, Knauber Farm failed to maintain complete treatment records for treated animals, specifically lacking information on the route of administration and withdrawal periods.
