(Salem, OR)  --  Oregon's Department of Agriculture is enacting emergency requirements for imported cattle in response to recent cases of bird flu in cattle found in other states.  Effective immediately, cattle exposed to, infected with or suspected to be carrying avian influenza or bovine influenza are not allowed to be brought into Oregon.  And dairy cattle coming from states with virus outbreaks need extra health certificates and special permission from the ODA.  The agency has also declared highly pathogenic avian influenza a reportable disease, regardless of species.
