大家都知道,食品应该是吃新鲜的,否则色香味会变差,严重的还会因腐败变质而丧失食用价值,甚至引起食物中毒。但是任何事物都有其两面性,有的食品如吃得太新鲜,则会对健康不利,或是使人得病。现列举如下: 牛奶最近有的报刊报道,某市农民牵着奶牛上街现挤现售,使市民既吃到了最新鲜的牛奶,还省了钱,又可防止牛奶掺水掺假,因此颇受市民的欢迎。其实这是愚昧的历史倒退。因为这种最原始的售奶方式,其挤奶的环境卫生,容器的洁净消毒,挤奶员的健康状况及双手的清洗消毒是无法保证的,故而早已被淘汰。况且 As we all know, food should be eaten fresh, otherwise the color and flavor will be worse. Seriously, it will also lose its edible value due to spoilage and even lead to food poisoning. However, anything has its two sides. Some foods, if they are too fresh, can be detrimental to health or make people sick. The following is a list of recent milk press reports: A farmer in a certain city is now selling cows on the street. This allows the public to eat not only the freshest milk, but also money saving, and prevents the adulteration of milk with water. Therefore, Welcomed by the public. In fact, this is a foolish historical retrogression. Because of this most primitive way of selling milk, its milking sanitation, clean container disinfection, milking staff’s health and hands cleaning and disinfection can not be guaranteed, it has long been eliminated.
