More than 30 people in a middle school in Henan province vomited, abdominal pain and diarrhea after meals, which was caused by food poisoning. The lunch eaten by students has gone bad, the hygiene of rice flour is not up to standard, and the tofu has an odor, which is harmful to students' health. There are also problems in the management of food delivery companies, and expired and deteriorated food is not found in time, which leads to food poisoning among students. In a middle school in Henan province, 30 students developed symptoms such as vomiting and diarrhea. The doctor said that they had acute gastroenteritis because they ate unclean food and the bacteria exceeded the standard. The food delivery company involved in this matter has stopped providing meals to schools and changed to regular food delivery companies to provide meals to students. ?

1. Students eat unclean food, have abdominal pain, diarrhea, fever and other symptoms, and are diagnosed as acute gastroenteritis by the hospital?

According to the student's description, I ate rice, noodles, fried meat with wax gourd and tofu for lunch that day. Tofu tastes bad, and the oil used for frying meat with wax gourd is also very greasy. The laboratory made a detailed test of rice and noodles and found that there was bacterial pollution, and the number of bacteria in it was much higher than the normal level. More than 30 students were taken to the hospital, and they all had symptoms such as vomiting, diarrhea, abdominal pain and fever. The doctor said that acute gastroenteritis was induced by eating unclean food.

Second, the food delivery company can't escape the responsibility, and it didn't find the spoiled food in time, which led to food poisoning of students.

This food delivery company has problems more than once and has no formal business qualification certificate. Some students ate foreign objects from the food delivered by the food delivery company, and some students thought that the food tasted cold and hard, so their management problems were also very serious. The phenomenon of student food poisoning this time is due to poor management of ingredients. Tofu has been stored for a long time, and it smells bad. The managers of catering companies did not find the problem in time, which led to food poisoning among students.

So, how do you think students' food safety should be guaranteed?
