Can preserved fish still be eaten when it is moldy?

I believe everyone has eaten preserved fish, which is a delicious traditional snack. However, if the pickled fish is moldy, can it still be eaten? This problem deserves our deep thought.

Causes and harm of mildew

The main reason why preserved fish is moldy is improper storage, which leads to mold growth. Mold is a harmful microorganism, which can produce toxins and pose a threat to human health. Common mycotoxins, including aflatoxin, ochratoxin and patulin, can cause a series of health problems such as liver injury, kidney injury and abnormal immune system.

Judgement of moldy degree

It is very important to judge the moldy degree of preserved fish. Mild mildew refers to the appearance of small mildew spots on the surface of pickled fish, and the mold has not penetrated into the fish. Serious mildew means that the surface of pickled fish is covered with mildew spots, and mold has penetrated into the inner layer of fish.

Mild mildew

If the pickled fish is only slightly moldy, with less mildew spots and does not go deep into the fish, the following methods can be adopted:

Clean up the mildew spot: wipe the mildew spot with a clean cloth or paper towel.

Drying: put the salted fish in a ventilated place to dry, so as to remove the musty smell and moisture.

Secondary processing: the salted fish is cooked again, such as frying or boiling. High temperature can kill the residual mold.

Seriously moldy

If the cured fish is seriously moldy and the mold has penetrated into the fish, it is not recommended to eat it. Even after cleaning, drying and secondary processing, mold and toxin can not be completely removed. Eating moldy preserved fish may lead to food poisoning, causing symptoms such as nausea, vomiting and diarrhea.

Measures to prevent mildew

In order to avoid moldy preserved fish, we can take the following preventive measures:

Proper storage: Store the salted fish in a cool and dry place, and avoid direct sunlight.

Vacuum packaging: packaging preserved fish in vacuum bags can effectively isolate the air and prevent the growth of mold.

Regular inspection: regularly check the salted fish for signs of mildew, and handle the slight mildew in time.

conclusion

Mildly moldy preserved fish can be eaten after proper treatment, and severely moldy preserved fish is not recommended to avoid food poisoning. In order to ensure food safety, it is suggested that you choose regular merchants to buy preserved fish and take effective preventive measures to avoid moldy preserved fish.
