I took a tour of a cruise ship butcher shop. These guys butcher in a temperature controlled room at 36 degree's. Very clean operation.
No rusty band saws. stainless steel tables.
Is that what I have to look for; for a once a year butcher shop ?
Well it wouldn't be a bad choice. There are professional butcher shops that will take game. Some require that you skin the deer first. Google or search your local yellow pages for one in your area. The one I have used in WA. charges 65 cents a pound. So it pays if you do the rough cuts first.
bswiv is right that we in the food industry are a bit more paranoid than is necessary for private consumption. But that's the ground I know and advice I give is from that professional view point.
He is also right in that you should be looking at cleanliness for a amateur butcher. Bleach solution or iodine based sanitizers should be evident. Equipment that easily cleaned and kept separate from the butchering area before use and in a separate area from clean tools after use. The butchering should also be done in an enclosed area that has been cleaned and sanitized.
The health department tells me the "danger zone" is between 45f and 140f. That is the range at which bacteria grows best. Ideally they want the time in that range to be as short as possible. The time limit I've been given is 4 hours from one extreme to the other.
It would be unlikely that hunters are going to meet the ideals that I'm expected to have in the kitchen.
If you're going to use a small time butcher then help him out. Gut, skin, and quarter Bambi, then but him on ice asap. If he doesn't have refrigeration, leave your ice chests, with fresh ice if needed, for him to use.
