(Portland, OR)  --  Luna the Arctic fox is receiving emergency medical care after being diagnosed with salmon poisoning.  That word from the Ochsner Park Zoo where Luna was sent to live just a couple of weeks ago.  Back in September, Luna was found abandoned in Portland and taken to the Bird Alliance of Oregon's wildlife rehabilitation hospital.  While undersized and malnourished, the fox was otherwise in good health when she came to the local animal hospital.
