Detecting Sulfamethazine Residues in Chicken Tissues Using the Delvotes SP System.

Sulfamethazine-spiked chicken liver and kidney were tested for residues using the Delvotest SP. The results were compared to a standard plate assay using Bacillus subtilis as the test organism. The Delvotest SP gave positive responses to all homogenized liver replicates spiked with sulfamethazine at or above 1.

Detecting Oxytetracycline Residues in Chicken Tissues Using the Delvotest P System.

Oxytetracycline spiked chicken liver and kidney were tested for residues using Delvotest P and the results compared to standard plate assay using Bacillus cereus as test organism. Delvotest P detected all replicates at concentrations of ≥0.62 μg/g in liver and kidney.
