legal analysis: there are two food safety grades, namely, food safety grade and sales food safety grade. The safety grade of catering food is divided into A as excellent, B as good, C as general level 3, and C is the default level. The safety level of food for sale is divided into four levels: A for trustworthiness, B for basic trustworthiness, C for dishonesty, D for serious dishonesty, and B by default. Food safety grade publicity is a grade evaluation made by the food supervision department according to the standard degree of daily management of licensed food business units. After the evaluation, a grade publicity board will be given without the operator's handling.

legal basis: article 148 of the food safety law of the people's Republic of China * * * consumers who suffer from food that does not meet the food safety standards may claim damages from the operators or the producers. Producers and business operators who receive consumer compensation claims shall implement the first responsibility system, pay first, 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 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 1,111 yuan, it will be 1,111 yuan. However, there are defects in the labels and instructions of food that do not affect food safety and will not mislead consumers.
