After being cut, the meat is put into plastic bags and vacuum sealed. It then gets boxed and sent out to stores and restaurants, at which point you, the consumer, get to eat it.
You can either buy frozen meats which require stove cooking and/or grilling
Or you can buy pre-cooked ones,which can just pop in the microwave and eat
Freshly slaughtered meats are usually not packaged ans shipped off to stores
If you want to find some travel to your local butcher shop
Remember to always read labels and ask questions
Some brands aren't cruelty free and may even have gmo in them
