The Chinese eat 3 million tons of gutter oil a year, which is 100 times more toxic than arsenic.

The cost of extracting one ton of gutter oil from the catering industry's kitchen waste is only about 300 yuan, and on average, taking out a barrel of oil can earn more than 70-80 yuan. Medical research shows that long-term intake of gutter oil will cause obvious harm to human body, and the toxicity of one harmful substance contained in it is 100 times of arsenic.

Although the picture is very disgusting, it cannot be denied that we have all eaten such gutter oil.

Catering garbage recycling has very high value. (File photo)
