Are exotic meats OK to feed?

I'm looking into exotic protein sources to get some more variety into my dog's diet. I feed a mix of raw and cooked, and feed chicken, turkey, beef, bison, salmon, pork and kangaroo already. I exclusively feed meats that are either USDA organic and 100% grass fed/free range or wild. I'm looking into things like emu and crocodile, as well as some fresh venison when deer seacon starts. I know to watch out for bovine spongiform encephally in beef and chronic wasting disease in deer-are there any other considerations? I feed mostly domestic red meat raw and wild meat or poultry cooked since she didn't do well on raw poultry and I don't want to transmit parasites from wild meat. Thanks!
