I understand that in Illinois all deer checked in are tested.

I buy elk from a ranch in western Illinois, They are tested when they are killed.

Illinois is not allowing ranches to import any new animals (deer or elk), but deer cross the mississippi sometimes, and wild elk have been sighted in some of the state's larger parks.

I don't know how they are being tested; the info I got from WU states that the USDA has a lock on the test. In addition we have been told in WI that we cannot get our deer tested, except via the DNR.
