Why do school canteens always like to cook with the necks or bottoms of chickens and ducks? That's disgusting. What's the harm to your health?
This is harmful. Animals have lymph in their necks. If you eat too much, you will get lymphoma. Chicken or duck's ass is the place where the most bacteria are hidden. Eating it regularly will lead to the growth of various cancer cells. You can find strong evidence on the Internet. After you find it, you should give it to the school for improvement and give you a healthy eating space.
