First. The more water you put in it the more likely it is to grow bacteria.if you are aging it, you don't want to put it in an airtight container. You want air to get on it. In the fridge or in a cooler one ice, it will be fine for a week. If you leave it in the cooler, don't let it sit in water. Leave the drain plug out and let the water drain. You want the meat dry.
Don't worry about the flies. Your meat is fine. Processing at home is rewarding. Now that I have a vacuum sealer, I like to do most of my deer.
