The use of the methylene blue test for the examination of cows milk was investigated in an inter-laboratory survey. A poor relationship was found between results of these tests and total viable counts. Coliforms were detected in a large number of pasteurized milks, indicating frequent post-pasteurization contamination. No relationship was found between the results of the methylene blue test and the presence of coliforms. Results from this survey highlight the need for reappraisal of the methylene blue test as a statutory method for the examination of milk. A total viable count and coliform test are suggested for providing information regarding dairy hygiene and the quality of the product at the point of retail sale.
在一项实验室间调查中，对亚甲蓝试验用于检测牛奶的情况进行了研究。发现这些试验的结果与总活菌数之间的关系不佳。在大量巴氏杀菌牛奶中检测到了大肠菌群，这表明巴氏杀菌后污染频繁。未发现亚甲蓝试验结果与大肠菌群的存在之间存在关联。本次调查结果凸显了重新评估亚甲蓝试验作为牛奶检测法定方法的必要性。建议进行总活菌数和大肠菌群检测，以提供有关乳制品卫生和零售点产品质量的信息。
