Not long ago, in Dongguan, Guangdong Province, a mother and daughter were sent to the ICU for emergency rescue after they suffered from nausea, vomiting, weakness of limbs, decreased blood oxygen saturation and other symptoms after eating home pickled pickles. They recovered after many days. Doctors detected Botox in their vomit and homemade pickle jars. It turns out that they have the habit of eating homemade pickles from old jars. The pickle jars have been used for 6 years, and vegetables are added regularly, but the "sour soup" in the jars is never replaced. Little did they know that the "sour soup" has been quietly polluted and poisoned by Botox, which led to this accident. Botulinum toxin is a kind of bacteria that grows in an anoxic environment. It has a strong viability in canned food and sealed pickled food. Botulinum toxin can be produced by botulinum toxin. Botulinum toxin is one of the most severe neurotoxins at present. A small amount of toxin can cause death, and the case fatality rate of botulinum toxin poisoning is as high as 35%. Here, we remind friends that if you have the habit of making pickles, you must pay attention to safety, and regularly replace the pickle soup or fully heat it to kill poison. Botulinum toxin is sensitive to heat and can be destroyed after 10 minutes at 100 ℃. In addition, those who have the following food at home should also pay attention, and it is better to discard them to avoid food poisoning. 1. Overnight braised food and cold dishes Overnight braised food and cold dishes are easy to breed bacteria because they are kept for too long. You should buy them now and eat them as much as you eat. Do not store them overnight. 2. The sprouted potatoes will produce a large amount of solanine after germination, which will stimulate the gastrointestinal mucosa and paralyze the respiratory center after eating, which is harmful to the human body. Discard the sprouted potatoes as much as possible. 3. The red or black sugarcane is usually a symbol of mildew, which may be caused by the contamination of sugarcane by Arthrobotrytis during transportation or storage and the production of toxins. Eating such sugarcane may lead to food poisoning. 4. The black spotted sweet potato has brown or dark brown spots. The skin of the sweet potato contains sweet potato ketone and its derivative sweet potato alcohol, which can damage the liver and cause poisoning after entering the human body. Nausea, vomiting and diarrhea may occur in mild cases, and high fever, asthma, convulsions, coma and even death may occur in severe cases. Therefore, the skin must be removed before eating the sweet potato. 5. As long as some of the fruits and fruits with mildew are mouldy and deteriorated, even if the rotten parts are removed, they are still inedible. Mouldy fruits contain a large number of harmful microorganisms and metabolites, which will cause food poisoning after consumption. 6. Bitter nuts Bitter nuts may have been contaminated by aflatoxin. Bitter nuts must not be eaten. 7. Do not eat black fungus or white fungus that has been soaked for a long time overnight or for a long time. If Auricularia auricula and Tremella fuciformis are infected with Pseudomonas coconutus, they may produce toxic oryzic acid after long-term storage. oryzic acid has strong heat resistance, and its toxicity cannot be destroyed by common cooking methods. Severe poisoning after eating can lead to death. 8. Rotten ginger. Rotten ginger will produce a strong toxin - safrole. Eating rotten ginger can cause liver cell poisoning and damage liver function. 9. Dead crabs must eat fresh crabs, steamed and eaten now, not dead crabs or overnight crabs. After death, the bacteria in the crab will multiply rapidly and spread to the crab meat,
