How to deal with a stupid oil mill with a business license and no small workshop certificate?

Cooking oil produced by a stupid oil mill with a business license and no small workshop certificate cannot be sold. Edible oil belongs to food, and the state is very strict in food safety management. To produce, process and sell food, you must have not only an industrial and commercial license, but also a hygiene license. It is ok for oil mills to produce their own edible oil without a license, and it is illegal to sell the produced edible oil. Unlicensed oil mills will be banned, warned and fined.
