A fungal toxins are harmful to carcinogenicity and mutation, and moldy food cannot be eaten!

Many people know that moldy foods cannot be eaten, because except for intestinal discomfort caused by heterologous microorganisms, the secondary metabolic products produced during the growth and reproduction of microorganisms -acute and chronic food poisoning caused by fungal toxins, the harm is more serious. In addition, fungal toxins have carcinogenicity and mutation and other harms.

A few days ago, Shanghai CDC -related experts revealed the scientific basis for us.

Once fungal toxins are contaminated, it is difficult to remove

In 1960, 100,000 turkey's bizarre deaths occurred in the UK. It was investigated that animal deaths caused by the pollution of fungal toxins were found. Since then, the harm of fungal toxins has gradually been discovered by humans.

A fungal toxin is a secondary metabolic product produced by agricultural products such as garden, fruits, and its products. More than 400 types have been found so far. A fungal toxin generally enters the animal and human body through food. Long -term consumption will produce a variety of toxicity for the digestive, immune system, and nervous system. A fungal toxin has the nature of corrosion resistance and high temperature resistance. It may contaminate food in all aspects of food production such as cultivation, planting, processing, transportation, and cooking.

Bacteria that are prone to different foods are different

Foods, fruits and other foods, whether in the storage phase of the growth stage or mature, such as in a humid environment in which the temperature is appropriate (25-35 ° C), it is very easy to breed fungal microorganisms. At the time of, "fungal toxin" will cause food, which will cause food to be polluted.

Due to the different types of food, there are differences in the breeding fungi, and the types of fungal toxins are different.

Peanuts and products are easily infected with yellow mold, and are contaminated with ribentic toxin B1 (AFB1).

Wheat and its products are easy to breed the Valley sickle bacteria, which are contaminated by deoxymal snow rottenxyne (DON) and corn gobrotone ketone (Zen).

The corn and its products are prone to breeding beaded sickle and the galcus sickle, which are contaminated by Fumarin B1 (FB1) and corn gobrotone (Zen).

Apple, hawthorn and its products are easily infected by picillin, which is contaminated with penicillin.

In addition, fungal toxins can contaminate animal foods by metabolism, such as riblomir B1 by dairy cows, which can produce M1, which is also harmful to the human body.

Common types of fungal toxin and its main hazards

Pay attention to buying channels in daily life and preserve food properly

1. Because fungal toxins can penetrate into the food and resist high temperature, conventional cooking methods cannot be eliminated. Therefore, the key to reducing the harm of fungal toxin is to prevent food mold.

When storing food, pay attention to ventilation, dryness and low temperature to prevent fungal growth and poisoning.

Food can be stored with vacuum, nitrogen filling, etc. to avoid fungal breeding.

Try to buy small packaging foods to avoid improper food storage after purchase, breed fungi, and produce toxins.

In addition to observing the appearance of food and smelling the taste, pay attention to the shelf life of food to prevent mildew changes.

2. Due to the accumulation of fungal toxins, after the feed that is contaminated by fungal toxins, the toxins will accumulate in the body. Therefore, when buying meat, eggs, milk and other livestock products, please buy products from regular manufacturers.

3. Clean up moldy food in time, so as to prevent fungus from continuing to infect more foods, causing fungal toxin pollution to spread. It is worth noting that the scope of pollution of fungal toxins is inconsistent with what the naked eye is seen. For mildew foods, even if the moldy part that can be visible to the naked eye, there may be fungal toxins. It is recommended to discard them.
