Last Modified: June 05, 2023

The following tables show the United States' status for animal diseases that are reported to the World Organization for Animal Health (OIE) if they are confirmed to be present in specific livestock, poultry, and aquaculture species. This information is reported to OIE every six months and is also presented on the international OIE website.                            

This is a summary of the report submitted to the OIE for the year indicated, and not meant to reflect current disease status.  Please see the Animal Disease home page for more current information.
