Throughout the years, I did worry about meat spoilage and even built a small walk-in cooler with an old fridge built through the back wall with the door off. By opening the insulated door and shutting a heavy screen door at night, I could maintain some kind of fairly good temperature. Sometimes in the late fall I would even have to put a small lightbulb in to keep from freezing.
Now we have a good local butcher shop in our small town. He only butcher's custom animals, has a half a dozen employees, and is just busy all the time. What amazed me most, is no matter the temperature, he is butchering five days a week, both beef and hogs. His kill site is about a mile from town, where he drops the innards, cuts off half the leg, lifts them up on a four-wheel-drive pickup With a bale hauling frame and brings them to town. His crew is ready and they proceed to skin out the legs and then hang the beef To finish skinning. He might bring 2 at a time. Pigs are skinned pretty much on a cart. They work with the door open, and when the critter is done, it is hoisted up and moved into a cooler. I remember when I was a lad, we never butchered on the ranch, during the heat of the summer. Watching the procedure at the butcher shop, change my mind when you could actually butcher a game animal, if you got the hide off and figured out some way to cool. True, you might have to bone out and place in a fridge, but it seems that an hour or two from kill to cool takes care of any problems.
