Before anything I use a wench to hoist the deer into the air so that it is not touching the ground.
First thing I do is open the deer from the private up to the sternum.
Then I remove the private parts by cutting a circle around them to make an island out of them then I toss those to the side.
Next I get into the body cavity and remove the intestines, stomach, liver, kidneys, lungs, heart, etc. I try to be careful and not cut or break open any organs as they are usually filled with bacteria that is harmful. This bacteria is used to break food down. Once the stomach is removed, I use a different knife to open the stomach and check the contents to see what the animal has been eating. Not for health reasons, but mostly for curiosity and how to set up a food plot that other deer in the area might be enticed to. I toss all the viscera to the side.
Next I skin the deer which is a long tedious process.
After it is skinned I process it by removing the head and legs. If it is going to be mounted, I leave a large cape of skin attached to the head so the taxidermist can mount it. I then cut the meat off the flanks and quarters then the tenderloins along the back.
Depending on how the meat will be used will determine how it is further processed. I can make deer steaks, grind it for deer burgers, dry it for deer jerky, or even finely grind it into what I call a chili grind for things like chili, spaghetti sauce, etc. There are various ways you can use deer meat.
When I am doing further processing I try to do it outside where it is cold so the meat doesn't get too warm. Once it's been processed I bag it, label it, and freeze it as quickly as possible. So far no one's gotten sick. My dad used to do it but his body isn't physically capable anymore. He's just old and wore out, LOL.
