The stinky tofu, which is famous for its stink, is really notorious this time. According to reports, more than a dozen stinky tofu factories in Shenzhen actually pickled tofu with dung water to increase its odor, and the finished tofu was wrapped in cloth and buried in the dung heap. Three industrial and commercial personnel vomited on the spot when they went to investigate. "One person even vomited bile." The best-selling stinky tofu is made of chemical dyes, rotten water, sewage and even manure. The fermented milk is mixed with a chemical agent, then precipitated, filtered after precipitation, and the filtered stool water is put in a basin or bottle, so that a few drops are sprinkled on fresh tofu when selling on the street, and stinky tofu will have a bad smell.
