The continuous and rhythmic contraction and relaxation of muscles at a frequency of 4 to 6 times per second is called muscle tremor, which is mainly caused by lesions of the substantia nigra and the nigrostriatal pathway, and is a symptom of central nervous system disorders. Encephalitis, craniocerebral injury, arteriosclerosis, basal ganglia tumor, some chemical poisoning, such as mercury, manganese chronic poisoning can appear muscle tremor of toxic effects. How to prevent the baby from poisoning caused by muscle fiber tremor? 1, avoid eating leftovers, try to eat now. Fresh meals are rich in nutrients, leftovers have a low nutritional value, and the more nutritious meals, the easier it is for bacteria to multiply, and if you don’t heat it up enough, it’s easy to cause food poisoning. After eating, nausea, vomiting, abdominal pain, diarrhea and other symptoms similar to acute enteritis can easily occur. Therefore, try to let the baby eat less leftovers. 2, when shopping for food, be sure to look at the production date and shelf life. And buy the food try not to put in the refrigerator for a long time, time may exceed the shelf life. At the same time, do not exist in a fluke, that food as long as not more than three days of shelf life, should not be a big problem. Because some food on the production date and shelf life of the label itself may not be fully consistent with the actual situation. After opening the package, we should pay attention to observe the food has no discoloration, change flavor, there has been a harla flavor of the food should not give the baby to eat, otherwise, eat such food is likely to make the baby food poisoning. 3, try not to give the child to eat processed cooked food. For example, canned meat food, a variety of meat sausage, bagged roast chicken. These foods contain a certain amount of preservatives and coloring, easy to deteriorate, especially in the hot summer. Eating them is easy to food poisoning. 4, some food itself contains toxins, to be processed to be safe to eat. For example: lentils contain toxic substances to the human body, must be fried and stewed through to eat, otherwise easy to cause poisoning; soy milk is nutritious, but raw soy milk contains toxic substances that are difficult to digest and assimilate, must be heated to more than 90 degrees in order to be decomposed, soy milk must be boiled through to drink; sprouting potatoes will produce a large number of loxin, so that people can not be poisoned, can not be given to the baby to eat. 5, some food cooking must be appropriate cookware. For example: can not use iron pot to cook hawthorn, begonias and other fruit acid content of high food, that will produce low iron compounds, resulting in baby poisoning.
