I've eaten a few different critters that have had some battle wounds, my concern with this one is the overall condition of the rest of the animal. If he just had a poke in his side that was healing up I wouldn't hesitate for a second to eat him. This elk has been sick for quite some time to get as skinny as his is. I bet he wasn't much over 500 on the hoof. Both hind quarters weigh about 70lbs...not each, together.
I also don't know if he's okay to eat just because he tastes okay?
It's hard to know if that injury is what was causing all of his problems, or if he had other problems and that's why the injury wasn't healing?
The infection isn't that uncommon with elk BUT that and it being so thin I would pass, FWP will certainly issue you another tag. The CWD is an excellent question, I would certainly not try to eat it without testing looking at it!!
There is no reported CWD in the elk in that area. That doesn't mean it couldn't be.
Thanks for all the input. I'll grind him up and feed him to the dogs.
On that note, our dogs eat wild game scraps all the time. As long as you introduce it slowly and feed it to them regularly it doesn't make them stink. If you accidentally leave your scrap bucket out after processing and your dog eats about 10lbs deer scrap, you'll have multiple problems, and the smell is the least of them!!
We see a lot of hoof rot in western WA and those animals are fine to eat as long as you trim off the tainted meat. That bull looks pretty rough though. Maybe check with state fish & game about a replacement tag, then feed it to the dogs. Maybe F&G will want you to surrender the animal to get a replacement tag.
