Yuzhno-Sakhalinsk, April 21 (INTERFAX) – The Russian Federal Service for Veterinary and Phytosanitary Surveillance (Rosselkhoznadzor) announced today that eggs imported from Krasnoyarsk Krai to Yuzhno-Sakhalinsk supermarkets contained excessive levels of quinolone antibiotics, with ciprofloxacin residues exceeding limits by twofold and enrofloxacin surpassing standards by nearly threefold. This food safety incident has sparked industry-wide reflection on upgrading detection technologies. Beijing Kwinbon, a Chinese innovator, has emerged as a key player in global food safety systems with its colloidal gold rapid test strips, which demonstrate exceptional performance in detecting quinolones.
Laboratory tests revealed that while the implicated egg samples passed 32 routine safety indicators, they failed to detect hidden antibiotic residue risks. Kwinbon’s Chief Technology Officer highlighted that its colloidal gold rapid test strips for quinolones utilize multiplex detection technology, enabling simultaneous screening of eight common quinolones—including ciprofloxacin and enrofloxacin—with a sensitivity of 0.5 μg/kg, fully compliant with EU and Russian residue limits. “Our on-site screening solution delivers results in just 15 minutes, nearly 100 times faster than traditional lab methods,” the official emphasized.
The oversight exposed in this incident aligns precisely with Kwinbon’s technological strengths. The company’s GT-810 Food Safety Rapid Detection System, paired with specialized test strips, allows visual interpretation without professional equipment. Operators with minimal training can conduct precise screenings at farms, logistics hubs, or retail outlets, reducing costs by 85% compared to laboratory methods. The product has obtained GOST-R certification in Russia and is widely deployed across food processing enterprises in the Far East.
Notably, Kwinbon has developed a comprehensive quinolone detection portfolio, including single-target test cards (detection limit: 0.5 μg/kg), triple-test strips (simultaneously detecting ciprofloxacin, enrofloxacin, and danofloxacin), and five-target kits covering 23 quinolone derivatives. Advanced lyophilization technology ensures test strips remain stable for 12 months at temperatures ranging from -20°C to 40°C, making them ideal for Russia’s extreme climate.
A Rosselkhoznadzor technical expert stated, “This incident has prompted us to reassess the strategic value of rapid testing. Kwinbon’s colloidal gold test strips successfully intercepted three batches of antibiotic-contaminated poultry during pilot applications in Sakhalin’s agricultural markets, proving their reliability.” Data shows the company’s products are now operational in over 200 rapid testing sites across Russia, with annual testing capacity exceeding 500,000 samples.
As global regulations on veterinary drug residues tighten, Kwinbon is deepening collaboration with Russian partners. Plans include establishing a joint food safety laboratory in the Far East to develop rapid detection solutions for emerging quinolones. Industry analysts note that expanding this “preventive testing” model will address withdrawal period compliance challenges and build robust technical safeguards for agricultural trade under the Belt and Road Initiative.
