近日，电商平台牛蛙样品检测发现多批次抗生素超标，其中部分样品检出禁用药物。[1]多地市场监管部门已对涉事产品予以封存，并送检进行进一步检验。[1]
牛蛙养殖规模持续扩大，2025年全国养殖产量约60万吨，产值约480亿元。[1]与此同时，从2015年到2024年的十年间，牛蛙产量增长率高达317.65%。[1]华南农业大学专家指出，高密度养殖、疾病防控不当和缺乏科学指导是导致抗生素超标的主要原因。[1]
检测发现的超标抗生素主要包括恩诺沙星、氟苯尼考和磺胺类药物，个别批次还检出呋喃西林等硝基呋喃类禁用药物及其代谢物。[1]国家禁用的药物包括氯霉素、硝基呋喃类和孔雀石绿。[1]长期过量摄入抗生素残留可能导致细菌耐药性、肠道菌群紊乱和过敏等潜在风险。[1]
专家建议消费者从正规渠道购买牛蛙并关注检测报告，同时呼吁监管部门加强源头把控和全链条溯源管控。[1]
Recent testing of bullfrog samples sold on e-commerce platforms has revealed multiple batches with antibiotic levels exceeding permitted thresholds, with some shipments containing banned substances [1]. Market supervision departments across the country have already impounded affected products and submitted samples for further examination [1].
Researchers from South China Agricultural University have identified several factors driving antibiotic overuse in bullfrog farming, including high-density breeding conditions, improper disease prevention practices, and insufficient scientific guidance [1]. The antibiotics most frequently detected in excess are enrofloxacin, florfenicol, and sulfonamide drugs, while some isolated batches have tested positive for banned nitrofuran compounds and their metabolites [1]. Authorities have prohibited the use of chloramphenicol, nitrofuran-class drugs, and malachite green in aquaculture [1].
The bullfrog farming sector has expanded significantly in recent years, with national production reaching approximately 600,000 tons valued at around 48 billion yuan in 2025 [1]. Output has surged 317.65 percent between 2015 and 2024 [1]. Experts caution that prolonged exposure to antibiotic residues in food may lead to bacterial antimicrobial resistance, intestinal microbiota imbalance, and allergic reactions [1]. The Ministry of Agriculture and Rural Affairs released technical guidance addressing spring season quality and safety risks alongside proper drug use protocols for bullfrog farming [1].
Researchers recommend that consumers purchase bullfrog products exclusively through authorized channels and verify inspection reports before purchase [1]. Simultaneously, they have urged regulatory authorities to strengthen oversight at the source and implement comprehensive traceability management across the entire supply chain [1].
