The pet food itself is burned. It is collected regularly throughout the processing, taken to a lab at the plant/factory making the food. Gound up, burnt then tested for mineral, quality, etc. The food is also monitored for size, color, and proper ingredients. If there's is a mistake the whole batch is rejected and goes to "fines" there it will either be remixed with properly made food, depending on how bad it was messed up or sent off to be used for other uses, pig feed and such. The actual quality of the food can change between batches, worker sifts and depending how attentive the people on quality check are at the time it's checked. Rejected batches = more paperwork as you can imagine...
You should be able to find some sort of info or code on your cat food bags that says the date, plant, and even shift that made it.
I'm sure I skipped a few details, if anyone still has any questions about how the food is made, tested, or anything else that happens before it is shipped I can have my husband explain it better tomorrow.
