Poisonous bean sprout is a kind of bean sprout harmful to human body. It looks fresh, but it contains at least four illegal additives, and urea exceeds the standard by 27 times. "No additives are allowed to be used in the production of bean sprouts," said Yang Hong from the Regulation Department of Shenyang Agricultural Committee. At least four additives were used in the black processing plant, among which urea exceeded the standard seriously, enrofloxacin was a veterinary drug, and 6- benzylamino adenine was a hormone. Adding urea and 6- benzylamino adenine can make bean sprouts grow thick and long, shorten the production cycle and improve the germination rate of soybean. However, after people eat it, nitrite will be produced in the body, which will cause cancer after long-term consumption. "
