Everyone has a refrigerator, stored food is also varied, vegetables and fruits, leftovers, fresh seafood, meat and eggs are regulars. When using the freezer on weekdays, many people think of the refrigerator as a safe. When all the ingredients are put in, they think everything is OK, that is, they can ensure the freshness of the ingredients and preserve the nutrition of the ingredients. Is this really the case?

Less than the teacher before we clarify this matter, first of all common science common ingredients most susceptible to what kind of bacteria, and the symptoms after infection:

1, milk is most susceptible to Listeria monocytogenes, there will be fever, cold, headache symptoms.

2, raw pork susceptible to Yersinia, there will be acute gastroenteritis, enterocolitis, and even appendicitis, septicemia, etc., known as "refrigerator enteritis."

In some cases, the refrigerator at home can indeed prolong the shelf life of food. However, extending the shelf life of the refrigerator does not kill the bacteria of the food but only inhibits the growth of some harmful bacteria through low temperature. For example, let's set the freezer at 4 ° C and the freezer at -18 ° C. However, not all bacteria are suppressed at these two temperatures and are not always available, especially in cold rooms.
