1, look at the thickness of the subcutaneous fat layer of pork. Don't buy pork with too thin and soft subcutaneous fat when buying pork. Under normal circumstances, the subcutaneous fat layer of lean meat pigs is obviously thin because of taking medicine, usually less than 1 cm; Normal pigs will have a layer of fat between the cortex and lean meat, and the fat is about1cm-2 cm. If it is too little, be careful.

2. Look at the color of pork. Under normal circumstances, pork containing clenbuterol is particularly bright red and bright. Therefore, if the lean meat is too red, the meat quality may be abnormal.

3. In addition, the pork can be cut into two or three fingers wide. If the pork is soft and cannot stand on the case, it may contain clenbuterol.

4. If there is obvious separation between fat meat and lean meat, and there is yellow liquid flowing out between lean meat and fat, it may contain clenbuterol.
