Besides humans, if it's learned behavior even or not, are there other species who are adverse to dirty foods?
Pigs are able to eat anything humans can, but they don't mind their food off the dirt ground covered in dirt, grass, sediment, water; basically unexpected crunchy stuff and textural stuff every time.
My dog picks up and drops their biscuit treats on the dirt. Many other animals eat already dead and rotting-on-the-floor animals.
But are there any animals that have been observed to clean off their foods, as in prepping it or at the very least not eating it as is? I don't know if that borderlines on the concept of cooking, which I believe is a human only invention. #science source
