摘要
本次检测共有149份生鲜乳样品,其中鲜牛乳96份,鲜羊乳53份。旨在了解陕西省生鲜乳中是否含有β-内酰胺酶及其残留状况。采用食品整治办[2009]29号指定检验方法4《乳及乳制品中舒巴坦敏感β-内酰胺酶类物质检验方法-杯碟法》。结果共检出17份β-内酰胺酶阳性样品,阳性样品检出率为11.4%。17份阳性样品中,鲜牛乳9份,鲜牛乳阳性样品检出率为9.4%;鲜羊乳8份,鲜羊乳阳性样品检出率为15.1%。17个阳性样品的dA与dB差值较大在6.08-13.3mm。本次检测样品阳性检出率较高为11.4%,且阳性样品中所残留的β-内酰胺酶含量较高,可见生鲜乳中抗生素和β-内酰胺酶监管形势依然严峻。
There are 149 samples of raw milk, including 96 cow's milk and 53 samples of goat milk. The objective is to supervising β-lac- tamase residues in raw milk. The method of testingβ-lactamase in raw milk is based on "cylinder plate method" published by Ministry of China Health. The result shows that β-lactamase is detected in 17 samples(relevance ratio: 11.4%). Among 17 samples, there are 9 samples of cow's milk (relevance ratio: 9.4%) and 8 samples of goat milk (relevance ratio: 15A%). The differences between bacteriostatic ring of 17 positive samples were among 6.08-13.3mm. The relevance ratio is 11.4% and the remainingβ-lactamase content in positive samples is higher. So antibiotic and 18 -lactemase still exist in raw milk,relevant government departments should strengthen the supervision.
