Precautions for eating seafood:

1, packed seafood should be refrigerated.

If the seafood has been cooked thoroughly at high temperature, you just need to put it in the refrigerator immediately and eat it after the next meal is heated. If the seafood is not fully heated but dead, it should be put into the cold room, thawed before the next meal, and then thoroughly heated and cooked. Don't crave the fresh taste.

Because the protein of seafood is delicate in texture and decomposes quickly, you should eat it within one day after taking it home, and it is not advisable to store it for a long time.

There are many toxins in dead shellfish.

The bacteria carrying capacity of shellfish itself is relatively high, and protein decomposes quickly. Once it dies, it will breed a large number of bacteria and produce toxins, and the unsaturated fatty acids contained in it are also prone to oxidative rancidity. Stale shellfish will also produce more amines and free radicals, which will pose a threat to human health (healthy food).
