what do you guys do when batch cooking rice to make sure it’s safe to eat?

i.e cool it quickly? How? How long do you keep cooked rice?

also poultry and prawns – do you cook and cool? How long does it keep? Do you reheat?

just after general advice really – feel a bit apprehensive about these items particularly so any advice would be good. Plus any other things you think I should know/avoid.
