牛奶营养丰富,容易消化吸收,是婴幼儿、老弱患者的重要营养品,故牛奶质量的优劣,直接影响上述人群健康,同时牛奶又是微生物繁殖的良好培养基,因此产销过程不卫生,就会造成微生物大量污染,其后果,不但引起牛奶变质,同时可能通过牛奶传播疾病和引起食物中毒。为加强牛奶卫生管理,我们于1979年冬季(2月至4月),夏季(6至8月)对郑州市乳牛繁殖场,进行消毒奶产销过程 Milk is rich in nutrients, easy to digest and absorb, is an important nutrition for infants, infants and young patients, so the quality of the milk will directly affect the health of the above groups, and milk is a good medium for the growth of microorganisms, so the production and marketing process is unsanitary, It will cause a large number of microbial contamination, the consequences, not only cause milk deterioration, at the same time may be transmitted through milk and cause food poisoning. In order to strengthen the management of milk hygiene, we conducted disinfection milk production and sales process in Zhengzhou dairy breeding grounds in winter of 1979 (February to April) and summer (June to August)
