What are the hidden dangers of food safety?

1, physical hazards, rational hazards include broken bones, gravel, iron filings, sawdust, hair, cockroaches and other insect residues, broken glass and other visible foreign bodies. Physical hazards not only pollute food, but also often damage the health of consumers.

2, radioactive pollution in food, including all kinds of radioactive isotope pollution of food raw materials and other hazards. Aquatic products such as fish have a strong enrichment effect on some radionuclides, which needs special attention.

3, chemical hazards, chemical hazards in food refers to the harm caused by toxic chemicals polluting food. Chemical hazards can lead to acute poisoning or chronic cumulative injury, including naturally occurring chemicals, residual chemicals, chemicals artificially added during processing and chemicals accidentally contaminated.

4. Fungal hazards. Fungal hazards in food mainly include fungi and their toxins, and poisonous mushrooms are harmful to food. Mold will destroy the quality of food, and some will also produce toxins, causing serious food safety problems. Such as aflatoxin, sterigmatocystin, ochratoxin, etc., can cause liver injury and have a strong pathogenic effect. Unlike bacterial toxins, mycotoxins can tolerate high temperatures.

5, virus harm, the virus is very small, not only invisible to the naked eye, but also invisible under the optical microscope, and it needs to be detected by an electron microscope. Virus pollution of food is not as common as bacteria, but once it happens, the consequences will be very serious.
