Abstract

Juvenile shrimp fed for 14 days on oxytetracycline (OTC) medicated feed with a potency of 1500 mg OTC kg-1 of feed reached a level of 33 μg OTC g-1 of shrimp tail muscle within 4 days, as measured by the microbial agar plate diffusion assay method for oxytetracycline in tissues, approved by the Association of Official Analytical Chemists. The concentration of OTC remained between 3.3-5.2 μg OTC g-1 of shrimp tail muscle from Day 4 through Day 14 of the feeding period. These concentrations were greater than the Minimum Inhibitory Concentration for sensitive organisms. By the fifth day following cessation of feeding medicated feed the drug content in shrimp tail muscle was less than the detectable limit for the method, or 0.4 μg of OTC g-1 shrimp tissue.
