小张与妻子小芳在一家化工研究所工作,效益一直不大好。因此,尽管他们十分喜爱自己的孩子,但就是没有能力为孩子订牛奶喝。去年,单位的效益开始好转,每人长了300元的工资。他们一核计,先给孩子订牛奶,以弥补从前的遗憾。 谁知,孩子饮用牛奶之后,经常出现腹部不适、腹泻等现象。大人马上想到是牛奶的质量有问题,他们拿着订的牛奶到消费者协会投诉,消费者协会不敢大意,马上送到有关部门检查化验,包括细菌培养。结果让小张 Xiao Zhang and his wife Xiaofang work in a chemical institute, the benefits have not been good. Therefore, although they love their children very much, they can not afford to order milk for them. Last year, the effectiveness of the unit began to improve, with a salary of 300 yuan each. As soon as they counted their nuclear program, they first gave their children milk to make up for the past regret.

Adults immediately think that there is a problem with the quality of milk, they hold a set of milk complaints to the Consumer Association, consumer associations not intended, and immediately sent to the relevant departments to test, including bacterial culture.
