In recent years, some illegal traders used low cost industrial alcohol to blend various kinds of liquor products (bulk Baijiu), which caused food borne methanol poisoning. With regard to foodborne methanol poisoning, Tianjin CDC said that the toxic effect of methanol on human body is caused by methanol itself and its metabolites formaldehyde and formic acid. The main characteristics are central nervous system injury, eye injury and metabolic acidosis. Human consumption of 5 ~ 10ml of methanol can cause poisoning, and 30ml can be fatal. Methanol, commonly known as xylitol and Xylin, is a transparent, colorless and toxic volatile liquid. It is widely used as industrial solvent and chemical raw materials. It can enter the human body through respiratory tract, skin and digestive tract and cause poisoning. There are two causes of poisoning: Mistakenly drink industrial alcohol containing methanol or use its blended fake wine. Industrial alcohol often contains toxic and harmful substances such as methanol and is inedible. Some illegal traders use cheap industrial alcohol to blend various kinds of liquor products (bulk Baijiu), which leads to food borne methanol poisoning. Therefore, food borne methanol poisoning is mostly caused by mistakenly drinking industrial alcohol containing methanol or drinking fake alcohol "mixed" with industrial alcohol containing methanol. Contact with alcohol based fuel in daily production and life. Alcohol based fuel is a fuel produced from alcohols such as methanol, ethanol and butanol. Alcohol based fuel is generally transparent and colorless, smells like alcohol and is liquid. It is easy to cause methanol poisoning after ingestion. In addition, industrial alcohol can also be used as glass cleaning agent. Because of improper storage, industrial alcohol is often poisoned by drinking baijiu. Generally, the incubation period after poisoning is 2-24 hours, and a few are up to 2-3 days. If ethanol is taken at the same time, the incubation period will be prolonged. The symptoms are dizziness, headache, nausea, vomiting, abdominal pain, irritability, blurred vision, etc. severe patients will have blindness, unconsciousness, convulsions, dyspnea and coma. Severe poisoning will lead to death. Tianjin CDC reminds us to raise awareness and self protection awareness of the hazards of methanol poisoning, and not buy Baijiu liquor with unknown origin. If methanol poisoning occurs or is suspected, seek medical attention as soon as possible to avoid life danger caused by delay. (outlook new era)
