The reporter found that there is a bag of rootless bean sprout regulator next to this table. According to law enforcement officials, this is a hormone pesticide that can make bean sprouts grow rapidly, which has carcinogenic and teratogenic effects on human body and is a chemical product prohibited by the state from being used in food production. These black workshops use these hormones to add water to accelerate the growth of bean sprouts. "Look, this bean sprout is almost 10 cm long, which is absolutely abnormal." He said that the growth cycle of this kind of bean sprouts with hormones is half that of those without drugs, and it only takes two days to grow, and the production cost is much lower. A worker said that they sell about 200 kilograms of tofu every day, most of which are sold to restaurants and restaurants in the urban-rural fringe.
