Statement of the Problem: Widespread use of antibiotics in animal husbandry for therapeutic and prophylactic purposes can lead to their transmission along the food chain and the accumulation of residual amounts in the food products. The systematic intake of antibiotic-containing food can result in various adverse effects and result in the emergence and spread of multiresistant forms of microorganisms. Therefore, there is a need for an efficient mass screening of food products for antibiotic content. Methodology: In this study, for the detection of ciprofloxacin (CIP) and chloramphenicol (CAP) as relevant antibiotics of fluoroquinolone (FQ) and amphenicol groups, a multiplex immunochromatographic test system has been developed. The assay was carried out in a direct competitive format using gold nanoparticles as a label for specific antibodies. Findings: After the optimization, the developed analysis allowed for the detection of CIP and CAP within 15 min with instrumental detection limits of 20 pg/mL and 0.5 ng/mL, respectively, and a visual detection limit of 5 ng/mL for both antibiotics. The assay showed cross-reactivity (69-160%) to 19 antibiotics in the FQ group. The developed test system was used to detect the antibiotics in a panel of dairy products. The obtained results indicate that it can determine CIP and CAP with high analytical characteristics. The analytical recoveries of CIP and CAP in milk samples ranged from 83-120%. Conclusion & Significance: The analytical characteristics of the developed test system meet the requirements of sanitary and hygienic control in the Russian Federation and EU countries and allow its use for the detection of antibiotics in milk and dairy products.
