Article Synopsis
- The paper discusses a method for quantifying sulfadimethoxine (SDM) and ormetoprim (OMP) in fish feed and fillets using LC-MS/MS, ensuring the method's reliability through assessments outlined by Brazilian agricultural guidelines.
- The calibration for both drugs showed strong linearity (r > 0.99), good precision (CV < 12% for feed and CV < 16% for fillets), and high trueness (97%-100% for feed and around 100% for fillets).
- A new approach to drug incorporation in fish feed involved coating pellets with ethyl cellulose polymer, which minimized drug leaching into water during the feeding process, maintaining release levels below 6% after
