The dining standards for students in primary school canteens are generally formulated by local education departments or relevant institutions according to national food safety standards. Generally speaking, standards will involve food quality, dining place, dining environment, food collocation, safety measures and so on. For example, primary school catering should ensure the variety, quantity, quality, safety and hygiene of food. School canteens should be equipped with special personnel responsible for food management and strictly implement food safety and hygiene requirements. At the same time, school canteens need to formulate a reasonable diet deployment plan, and scientifically formulate daily meal standards according to students' age, gender, physical condition, climate and other factors. In short, the dining standards in primary school canteens should be based on the health and safety of students, so that students can enjoy delicious food in a healthy and safe dining environment.
