Meat or fat products can draw animals that you might not want around, like dogs, coyotes, raccoons, foxes, skunks, bobcats, bears, etc. I don’t know what you might attract in Thailand. They can dig into your compost and make a mess, plus they are then hunting on your property. That can lead to other destruction. They can also go rancid and stink. Meat can draw flies which lay eggs that turn into maggots. Those are the reasons I know of that you might not want to put meat or fat in your compost.
I do sometimes put meat or fat in, especially when I am just starting the pile. I bury it at the bottom and have none of those problems. I also have a screen I can throw over mine that helps keep digging things out. I’ve buried rabbits and chickens way down in there. When I do that, I don’t turn the pile for a long time.
