Authorities in Peru have reported a case of HPAI on a commercial duck farm in Chancay.  Affected ducks showed neural, respiratory and digestive abnormalities with initial mortality attaining 10 percent of the flock at the time of diagnosis.  Approximately 3,500 birds were depopulated.

The second case involved a commercial laying flock of approximately 6,000 hens in Grocio Prado.  The diagnosis was made following mortality in the flock with typical clinical signs of HPAI.

Brazil reported cases of HPAI strain H5N1 from migratory waterfowl but to date, has not reported any cases in commercial poultry.  Argentina and Uruguay have recently documented mortality in sea lions consistent with previous reports along the Pacific coastline.
