Prototype for rapid test devices to detect residues of sulfonamides in chicken carcasses from traditional breeders in Surabaya, Indonesia

Background and Aim: Sulfadiazine, one of the sulfonamide group’s active compounds, is widely used for therapeutic production against several diseases. Veterinary drug residues can have a significant impact on human health conditions. This study aimed to develop prototype rapid test devices (RTDs) detecting sulfadiazine chicken carcasses based color indication. Materials Methods: Seven samples collected from traditional breeders in Surabaya-Indonesia were prepared tested using RTDs. sample represents population considering that last report, use antibiotics was more than 40%, while ability monitor RTDs estimated at 100. The standard purple by Hex code or decimal compare positive samples. A light-emitting diode (LED) lamp observe color. Analysis sulfonamides resulting compared ultraviolet-visible spectrophotometer. Results: Sulfonamides contamination levels 50% 100% detected concentrations 0.472 µg/mL 0.642 µg/mL, respectively. <0.395 did not appear purple. Conclusion: study’s findings showed be detect limit detection 0.5 after 45 min exposure an LED operating wavelength 980 nm (p < 0.05). limitation being able presence bound fat Rapid developed commonly monitoring due limited technology available market.
