How to judge whether fish meat has gone bad

Smell whether the fish meat has a strong fishy smell

Whether it is cooked fish or raw fish, it smells fishy. As the fish slowly spoils, the fishy smell will become stronger and stronger. When the fish starts to smell unpleasant, throw it away.

Feel if the surface of the raw fish is slimy to the touch

The skin of the fish will become wetter and wetter, eventually secreting a thin layer of mucus. When the above changes occur, there is no doubt that the fish meat must have gone bad. Once the surface of fresh fish becomes slimy, it must be thrown away immediately, but cooked fish will not feel slimy even if it goes bad.

Check whether the raw fish has turned milky white

Normal fish meat is light pink or white, with a thin layer of transparent liquid on the surface. As the storage time becomes longer and longer, the fresh fish will become milky white. Fish or refrigerated fish will go bad, and the surface of the meat will be glossier and turn milky white. The milky white part may show a little blue or gray. Cooked fish meat will not turn milky white. The above signs of fish spoilage will only appear on raw fish.

Raw fish that has been refrigerated for more than 2 days after the sell-by date must be thrown away

To extend the shelf life of the fish, you must freeze the fish. If the fish package says edible The expiration date is not the sales expiration date, so try not to store the fish longer than the previous date. The "use by" date means that if you haven't eaten the fish by this day, the fish will begin to deteriorate.
