[目的]分析新丝绸之路经济带西部地区牛肉质量安全风险因子.[方法]通过对我国新丝绸之路经济带西部地区肉牛养殖过程的跟踪调研, 分析肉牛养殖过程可能使用的药物, 对比分析国内外对肉牛养殖用药和牛肉中重金属及兽药残留限量要求, 检测分析这些地区牛肉中铅、汞、砷、镉、铬5种重金属和氯霉素、硝基呋喃类 (4种) 、盐酸克伦特罗、己烯雌酚、杀虫脒、阿维菌素等9种兽药残留.[结果]这些地区牛肉中重金属污染远低于国家标准限量要求, 所有样品中所检兽药均为未检出, 质量安全风险低.[结论]该研究为广大消费者提供借鉴.%[Objective] The research aimed to analyze the quality and safety risk factors of beef in the western region of the New Silk Road Economic Belt.[Method] By following up and investigating the beef cattle breeding process in the western part of China's New Silk Road Economic Belt, the paper analyzed the drugs that might be used in beef cattle breeding process. And compared the requirements of domestic and foreign limits on the use of beef cattle breeding drugs and the residues of heavy metals and veterinary drugs in beef. 5 kinds of heavy metals such as lead, mercury, arsenic, cadmium and chromium, 9 kinds of veterinary drug residue, as chloramphenicol, nitrofuran (4 kinds), clenbuterol, diethylstilbestrol, chlordimeform, and avermectins, were detected and analyzed in these areas.[Result]The heavy metal pollution in beef in these areas was much lower than the national standard limit requirement. The veterinary drug residues in all samples were undetected and the quality and safety risks were low.[Conclusion] This research provides reference for consumers.
