Several typical food contamination incidents.

1. blending toxic soy sauce with crude water 200 1 June, Chongqing seized Wanzhou sankai biochemical factory to sell cystine waste liquid to soy sauce factory to blend soy sauce. The State Council attaches great importance to this matter. Cystine, commonly known as "hair water", is a kind of waste liquid, which should be treated and discharged. It contains lead, arsenic, aflatoxin, 4- methylimidazole and chloropropanol which are harmful to human body. In addition, there is water-injected meat that has been harmful to consumers for a long time. Adding whitening agent to flour makes the whitening agent of flour exceed the standard, forming a popular "toxic flow" in the food field.

2. Guangdong Poisonous Rice Incident From June 5438 to February 2000, consumers in Jiangmen City, Guangdong Province were poisoned by eating rice mixed with mineral oil. Shortly after the consumer was poisoned, the epidemic prevention department of Jiangmen City seized 3 tons of poisoned rice in the inventory. Since then, toxic rice in the Guangdong market has been discovered one after another. The investigation found that the poisoned rice on the market is actually an expired war grain reserve. According to relevant regulations, these spoiled rice can only be used for industrial purposes. The criminals mixed old rice with industrial oil such as mineral oil to enhance the luster of rice and then sold it. These industrial oils contain a variety of toxic substances, among which aflatoxin exceeds the standard. After eating food seriously contaminated by aflatoxin, people will have symptoms such as fever, abdominal pain and vomiting, and in severe cases, they may have symptoms such as pulmonary edema, spasm and coma.

Third, the exposure of the "black heart" moon cake case in Nanjing Guanshengyuan is quite dramatic. CCTV reporters conducted a whole year's follow-up investigation on Nanjing Guanshengyuan Moon Cake Factory. On the 9th day after the Mid-Autumn Festival, the mooncakes worth millions of yuan that Guanshengyuan Food Factory didn't sell out in that year were collected from all over the country and transported to the workshop covered with enough paper. There are three kinds of recycled moon cakes: bean paste, pineapple and lotus seed paste. Peel and fill, stir and fry again, put in storage and refrigerate, and use it next year. Moldy fillings will be recycled. Finally, all these fillings will be sent to the production line and processed into new moon cakes. It is conceivable that this kind of expired and moldy moon cake will do harm to the body after eating. However, the person in charge of Nanjing Guanshengyuan Food Factory plausibly said in front of reporters: "It is a common phenomenon in China to make new cakes with old cakes." After the incident, the market exploded. Consumers' trust in the quality of moon cakes fell to the lowest point, and "Nanjing Guan Sheng Garden" finally closed down.
