List the food safety hazards around you and talk about the hazards.

1 Sanjiang Shopping Supermarket often buys daily necessities and fresh vegetables. Several times, I found that the eggs I bought went bad and moldy within two days, and the broccoli I bought the day before yesterday was picked for a long time. When I brought it back, I found that many of them were moldy and could not be eaten at all. Because of my living habits, I simply threw them away.

Moldy food tends to have diarrhea.

The easiest way to teach you is to look at the date of production. Once the expensive eggs are not fresh, it is no use sprinkling yellow or moldy. Generally, eggs within 15 days are the freshest, but many high-priced eggs in supermarkets are still sold after 15 days, because the price will be twice or more higher than ordinary eggs, and citizens will not give priority to buying them, resulting in stocks after 30 days. Especially in summer, I suggest you don't buy boxed eggs, but choose one by one.

Five eggs, experienced chefs should be able to see at a glance, the top is broken, microorganisms will multiply rapidly, it is best to eat them all at once. The egg on the left in the middle is very bright, and the pores look small and smooth. Don't think this kind of egg is fresh. If you see it in the food market, you must not choose. It must have been there for a long time The egg on the right looks complete, but if you look closely at the gray dots on the eggshell, nine times out of ten, this egg is yellow. The egg on the lower right is the bad egg I asked the store for. There are usually such obvious black spots, which means it must be corrupt. Just throw it away, don't waste your feelings.

The egg on the left is pink with a thin layer of frost, which is rough to the touch. Generally, you can choose fresh eggs in an intuitive way.
