云南大理虹鳟鱼安全指标评估分析

Evaluation on the Safety Indices of Oncorhynchus mykiss in Dali City of Yunnan Province

[目的]对云南虹鳟鱼主要产区的虹鳟鱼的安全指标进行测定。[方法]以云南虹鳟鱼主要产区大理剑川的虹鳟鱼为研究对象,采用原子吸收分光光度计、液相色谱串联质谱仪等检测虹鳟鱼中重金属、兽药等成分的含量,并评估其安全指标。[结果]在检测的虹鳟鱼样品中,仅有2号养鱼场样检出无机砷含量超标,其他挥发性盐基氮、重金属及兽药共16项指标均低于国家淡水鱼NYT842-2012标准。[结论]该研究结果为制定云南虹鳟鱼地方标准奠定了基础。

[ Objective ] The research aimed to determine the safety indices of Oncorhynchus mykiss in main producing areas of O. mykiss in Yunnan Province. [ Method ] Taking O. mykiss in its main producing areas in Yunnan Province as research objects, the content of heavy metals, veterinary drugs and other ingredients were detected by using atomic absorption spectrophotometer and LC/MS and the safety indices were evalua- ted. [ Result ] Among the detected samples of O. mykiss, the content of inorganic arsenic in the samples from No. 2 fish field was out of stand- ards, but other 16 indices such as contents of total volatile basic nitrogen, heavy metals and veterinary drugs were lower than National standard NYT842-2012 of freshwater fish. [Conclusion] The research results laid the foundation for making the local standards of O. mykiss in Yunnan Province.
