Salmonella is resistant to low temperature and can survive in the refrigerator for 3 or 4 months. But at the same time, Salmonella is not heat -resistant, and it will die when the temperature inside the egg reaches about 71 ° C. Therefore, if ordinary eggs should be fully heated, they can be eaten after cooking, so that food safety can be guaranteed.
