贵州省都匀市散养户生鲜乳质量安全监测
Discussion on the monitoring results of quality and safety of raw milk from smallholder dairy farmers in Duyun City
目的 对都匀市5户奶畜散养户进行全覆盖监测,为散养户生鲜乳质量安全监管提供依据。 方法 2023年3月,采集都匀市5户奶畜散养户储奶罐样品,按照GB 19301-2010《食品安全国家标准 生乳》中检验方法测定蛋白质、菌落总数、黄曲霉毒素M1(AFM1)、三聚氰胺、铅(Pb)、铬(Cr)、汞(Hg)、砷(As)等8项指标。 结果 5个样本中4个达到标准,合格率为80%,其中蛋白质、AFM1、三聚氰胺、Pb、Cr、Hg、As等7项指标的合格率为100%,菌落总数的合格率为80%。 结论 都匀市辖区内散养户生鲜乳总体质量稳定,整体安全水平可控,个别样品存在菌落总数超标风险。
Objectives Full coverage monitoring was conducted on 5 small-scale dairy farmers in Duyun City, Guizhou Province to provide a basis for the quality and safety supervision of raw milk from these farmers. Methods Samples from the storage tanks of milk in 5 small-scale dairy farmers in Duyun City, Guizhou Province were collected in March 2023 to measure 8 indexes including the content of protein, aflatoxin M1 (AFM1), melamine, lead (Pb), chromium (Cr), mercury (Hg), arsenic (As), and the total count of colonies with the testing methods specified in the "National Food Safety Standard for Raw Milk" (GB 19301-2010). Results 4 out of 5 samples met all standards, with a compliance rate of 80%. Among them, the compliance rate of protein, AFM1, melamine, Pb, Cr, Hg, and As was100%, and that of the total count of colonies was 80%. Conclusions The overall quality of raw milk from small-scale dairy farmers within Duyun City, Guizhou Province was stable, and the overall level of safety was under control. However, there was a risk of exceeding the total count of colonies in some samples.
