Dominican Republic, Italy report avian flu outbreaks

In the latest avian flu developments, the Dominican Republic reported a low-pathogenic H5N2 outbreak at a commercial poultry farm, and Italy reported three more outbreaks involving the highly pathogenic H5N8 virus, according to notifications from the World Organization for Animal Health (OIE).

In the Dominican Republic, veterinary officials said an abnormal number of deaths and a drop in egg production beginning on Sep 30 at a commercial layer farm in Espaillat province prompted testing, which pointed to avian flu. Samples sent to the National Veterinary Services Laboratory in the United States confirmed low-pathogenic H5N2.

The virus killed 1,953 of 48,877 susceptible birds. Authorities quarantined the eggs, which will be disposed of, and the remaining birds are slated for culling. Enhanced surveillance will take place in the area surrounding the farm, and the barns will be thoroughly cleaned in disinfected, officials said.

An investigation hasn't determined the source of the outbreak, which is the Dominican Republic's first since 2009.

Elsewhere, Italy—one of a few European countries to report ongoing H5N8 activity over the summer—reported three more outbreaks, all in Lombardy province in the north. The events began between Oct 23 and Oct 25, striking a duck farm and a layer farm, as well as a backyard holding housing a goose and five ducks. Taken together, the virus killed 100 of 16,218 susceptible birds, and the surviving ones were slated for culling.
