It doesn’t seem like there is a tag slaughterhouses. There is the generic landuse=industrial + industrial=slaughterhouseTag:industrial=slaughterhouse - OpenStreetMap Wiki, but that’s for the generic area, not a specific business.
The key difference is that whole herds of live animals are brought to a slaughterhouse, while a hunter brings a single deer carcass at a time (or maybe a few) to a processing facility. Some may be large and might make sense to tag as industrial=* (or man_made=works). Others are small home based businesses that only operate around hunting season. These might more feel more appropriate under the craft=* key.
A deer processor can be accurately described as a “butcher”, but not a “butcher shop” because they don’t sell the meat. They just provide a service to hunters and give the meat back to them. So shop=butcher is wrong for this, but perhaps craft=butcher? It does have a little bit of use so far.
FWIW the 39 craft=butcher are here. Most are in Germany. A couple of the ones outside of Germany have indicated “not a shop” (also here). Some of the ones inside Germany also look “larger than just a shop”.
Notwithstanding that, a deliberately different tag (e.g. as suggested above) would avoid any confusion.
In my local neck of the woods the hunters process the game close to where they shot it. They do that themselves, or if they are of the kind “wealthy shooters buying a shoot” have rented hands to do that. Anything else will require a butcher and quick moving of the body.
UPDATE to clarify: Hunters just remove the intestines, cutting the meat most always with a butcher.
(OT on slaughterhouses) I suspect that many just aren’t mapped at all, because they often don’t advertise their presence much (thought locals will of course know that they are there). FWIW in the UK there’s a list here (under OGL) and the nearest one to me (actually part of the Food Standards Agency) is in the unmapped pink space here.
I second the idea to make this work for game other than deer.
If I think about my local customs and legislation, there would be a difference between a facility where
a carcass is partially processed and sold unskinned, or is fully processed only for the hunter’s own use (some legislative suggestions about basic hygiene. I think it’s assumed the local hunting organisation runs the facility)
a carcass is fully processed but only sold in very small quantities (more specific legal requirements e.g. regarding the QC of hygiene and cold storage, I think it’s assumed this kind of facility is run by a local hunting organization to fund their activites, and may be shared by multiple organizations, farmers etc. in a rural community)
fully commercial operation, legislative requirements include having a vet checking individual carcasses before processing etc.
One difference from the current language of the proposal is that these facilities (type 1 and 2) are perhaps a bit more communal, and offered also/primarily as local food processing and storage facility rather than ”game processing as a service”.
(Sorry for potentially inaccurate English terminology.)
This is a commercial facility, but still works on a similar process of roo’s being shot in the field, with their carcasses then delivered to established cold rooms, from where they’re collected for processing.
I have heard of some places also doing similar with wild goats, & I think even pigs?
craft=animal_processing - An improvement over deer_processing as it allows for facilities processing any sort of game animals. It may be a bit too general though as animal could easily be taken to mean farm livestock as well. It’s unclear to me if separate tagging for livestock vs game processing facilities would be desirable, but if so then a more specific term would be better.
craft=game_processing - More specific term using hunting meaning of the word “game” to indicate a specific subset of animal processing. May not always translate clearly to other languages since the word “game” has a number of different meanings.
craft=wild_game_processing - Same as above, but “wild game” should hopeful survive translation better than just “game”.
I think it is appropriate to have a more general tag. However, what would make a good subtag for specifying the animals processed?
It seems key:animal is currently in use, but has some unusual guidance, instructing mappers to assign it to pastures, as well as buildings, and even as a way to specify certain facilities, such as animal=cemetary.
Would this be an appropriate subtag for a game processor?
