1, control the storage time, store the purchased cooked food in bulk as little as possible and eat it in time. Cooked food that needs to be eaten after changing knives should be replaced immediately before eating, and should not be stored for a long time after changing knives.

2. Avoid cross-contamination. Unfinished cooked food should be kept in cold storage. When storing, attention should be paid to placing raw and cooked foods in layers (cooked and raw), storing them in containers or wrapping them with plastic wrap to avoid cross-contamination during taking and placing.

3. Reheat before eating to avoid eating cooked food stored overnight or for a long time. Cooked food stored for too long is easy to breed germs; Even if you need to eat it, you should first identify the cooked food with your senses, and then heat it to the central temperature above 70℃ (burn through) for about 3 minutes to kill the bacteria that may exist in the cooked food through high temperature.
