The compensation standard for expired products is: if consumers buy expired products, they can ask the supermarket to refund the purchase price of expired and deteriorated food, and compensate for the loss equivalent to twice the amount of the purchase price, that is, increase the amount of compensation by twice the price of the goods or the cost of receiving services, or they can ask the merchants to buy one and lose three. If negotiation fails, the consumers can apply to the arbitration organ for arbitration, or they can directly file a lawsuit with the people's court and deal with it through litigation procedures.

article 49 of the law on the protection of consumers' rights and interests: if a business operator commits fraudulent acts in providing goods or services, it shall increase the compensation for the losses it has suffered according to the requirements of consumers, and the amount of the increased compensation shall be twice the price of the goods purchased by consumers or the cost of receiving services.

according to article 148 of the food safety law of the people's Republic of China, if a consumer suffers from food that does not meet the food safety standards, he may demand compensation from the operator or the producer. 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 may, in addition to demanding compensation for losses, demand compensation of ten times the price or three times the loss from the producers or operators; If the amount of additional compensation is less than 1, yuan, it will be 1, yuan.
