Harm of spoiled food:
Eating spoiled food will, damage the liver, gastrointestinal tract, etc., but also cause cancer.
Mold food poisoning
Mold food poisoning is mainly caused by a small number of toxins produced by toxic molds. One species or strain can produce several different toxins, and the same toxin can be produced by different molds. The test results of contaminated molds show that the main contaminants are Aspergillus and Penicillium, the main contaminants of meat are Thamnidium elegans and Trichoderma (Mucor), etc., and the main contaminants of feed are Aspergillus, Penicillium and Ephelis.
Common mycotoxin food poisoning:
(1) aflatoxicosis aflatoxin poisoning (aflatoxicosis) aflatoxin is Aspergillus flavus (A.flavus) and Aspergillus parasiticus (A.parasiticus) produced a class of structurally similar metabolic mixture of products, there are 17 kinds of more. Their basic structures are difuran ring and coumarin, the former for the basic toxic structure, the latter for carcinogens. Aflatoxin is very stable, heat-resistant, in the melting point (200 ℃ ~ 300 ℃) will not decompose, and its toxicity is very strong, the main damage to the liver, so that the liver cell necrosis, hemorrhage and bile ducts hyperplasia, there is an obvious carcinogenic effect. Aflatoxin-producing molds mainly contaminate grain and its products, peanuts, peanut oil, rice, cottonseed, etc., milk, salted fish, etc. are also contaminated.
(2) trichothecene toxicosis (trichothecene toxicosis) trichothecene wheat poisoning is eaten by the trichothecene wheat food poisoning phenomenon. Caused by wheat trichothecene toxicosis of pathogenic bacteria is mainly Fusarium (Fusarium) in the Fusarium graminearum (F.graminearum), Fusarium tandem beads (F.moniliforme), Fusarium acanthamoeba (F.axysporum), Fusarium oat (F.avenaceum) and so on. They can produce two types of mycotoxins, erythromycin wheat toxin, which can cause vomiting, and zearalenone, which has an estrogenic effect.
(3) yellow rice toxicosis (yellow rice toxicosis) contaminated by mold metabolites yellow rice, known as yellow rice. According to the different contamination mold, yellow rice can be divided into three kinds, namely, yellow green green mold yellow rice, yellow green green mold (P.citeoviride) produced by yellow green penicillin (citreoviridin) contamination, this toxin toxicity is strong, infringement of the nerve, can lead to death. The second is the orange penicillin yellow rice, which is contaminated by orange penicillin (P. citrinum) toxin orange cyanotoxin (citrinin), this toxin is mainly damage to the kidneys, causing substantial lesions. The third is the island green mold yellow rice, which is contaminated by the island green mold (P. islandicum) produced by the yellow sky essence (luteoskyrin) and the island green mold toxin (islanditoxin) two toxic liver toxins.
(4) ergotism (ergotism) This type of poisoning is caused by eating wheat or wheat products with ergot. The pathogenic bacteria for ergot (Claviceps purpurea), this bacterium can form ergotamine, ergot alkaloids and ergot alkaloids three types of alkaloids, including ergotamine can cause food poisoning, acute nausea, vomiting, abdominal pain, diarrhea, heart failure, coma, etc. Chronic have different symptoms.
In addition to the above, there are also mold poisoning of sugarcane and other food poisoning caused by mold toxic metabolites.
When people accidentally eat food contaminated with pathogenic bacteria, or toxins produced by bacteria and molds, symptoms of poisoning, vomiting, diarrhea, headache, elevated body temperature, or even bloody stools, difficulty in swallowing, speech impediments, respiratory distress and death will occur.
