3 types of fish not to buy
Freezer-burned fish
For frozen fish, when buying, you need to observe carefully. If you see the fish meat is pale, hard as ice, it is best to avoid it as it indicates that the fish has been frozen for a long time, the meat is spoiled, and it is no longer fresh and tasty. Long storage time also reduces the nutritional value of the fish.
Fish with unpleasant odor
Fish naturally have a fishy odor, but it should not be too strong or have an unusual smell. If you find that the fish has an excessively fishy or pungent smell that is intolerable, it indicates that the fish is no longer fresh.
In addition, if the fish has a petroleum-like smell, it is also not recommended to buy. This may indicate that the fish has been raised in a polluted water environment, which is harmful to the health of consumers.
If you find that the fish has a disinfectant odor, you should also avoid buying it. The seller may use formaldehyde to soak the fish, which helps to keep the fish fresh for a longer time. This substance has the ability to disinfect and enhance the color of the fish meat, but it is extremely toxic to human health.
Fish with peeling scales
Fresh fish will have firmly attached scales, a bright color, and a shiny appearance. Fish that are diseased or weak will have loosely attached scales that easily come off.
