Article 148 of the Food Safety Law of People's Republic of China (PRC) stipulates that consumers may claim compensation from operators or producers for eating food that does not meet food safety standards. The producers and operators who accept the consumer's claim for compensation shall implement the first responsibility system, pay in advance, and shall not shirk; If it is the producer's responsibility, the operator has the right to recover from the producer after compensation; If it is the responsibility of the operator, the producer has the right to recover from the operator after compensation. In the production of food that does not meet the food safety standards or in the operation of food that is known to fail to meet the food safety standards, consumers can demand compensation from the producers and operators for losses that are ten times the price or three times the loss; If the additional compensation amount is less than 1000 yuan, it is 1000 yuan. However, the labels and instructions of food have the defects of not affecting food safety and not misleading consumers.
