RIGA, Nov. 27 (Xinhua) -- An outbreak of a highly contagious bird infection has hit a flock of 35 chickens at a backyard poultry holding in the western Latvian municipality of Talsi, the country's Food and Veterinary Service said on Thursday.
Latvia had previously reported no cases of Newcastle disease in domestic birds, though laboratory tests showed the virus has been circulating in wild bird populations.
