You must always be careful to cook food properly, especially things like meat.

It must get very hot, and be cooked right through or it may not kill all the germs in the inside.

When food is very very hot, it kills the germs and bacteria.

 You must be especially careful with chicken. It should not be pink, and when you poke something in the meat, it should not ooze out pink liquid.

Always check round chicken bones, and don't eat chicken that isn't cooked properly. It can make you so sick, you have to go to hospital.
