This practice is particularly unsanitary, regardless of the health of consumers, and it should be severely punished and rectified. Such behavior should give diners and consumers a statement, because after all, many people still trust McDonald's, and this situation will affect everyone's trust in McDonald's. It will also affect their future business. From tea to seafood to fast food, from restaurants among online celebrities to listed companies, the irregular use of expired ingredients in the catering industry broke out in a large area, which is a scandal of cost calculation and management loopholes, and it is also the disorder of values in the race. Food safety and hygiene has always been the top priority of people's livelihood, and McDonald's has always been a more formal foreign company in the hearts of ordinary people. But it is such a regular foreign company that broke the news, using expired ingredients, using the tray without washing or wiping, and continuing to use the milk that has been leaked for three days. This is a serious violation of the Food Safety Law and an illegal act of making people's lives and health a joke. I hope that the relevant departments will intervene in this matter and give the people a statement. This is a serious violation of China's food safety law. Consumers can complain or report to the administrative department for industry and commerce when purchasing expired food or food made from expired raw materials. The administrative department for industry and commerce shall file a case for handling. According to the provisions of the Consumer Protection Law, the sales unit may be required to compensate the consumer and ask for a refund. At the same time, relevant departments can also punish sales units according to the investigation.
