Bird die-off disease strain identified
--------------------------------------
A virulent strain of Newcastle disease is responsible for the death of nearly 1000 gulls and 500 cormorants in Minnesota this summer [2010]. The specific strain of Newcastle disease was confirmed this week by the National Wildlife Health Center in Madison, Wisconsin.
The practical implication of this finding is that Minnesota poultry producers should practice sound biosecurity procedures, including the monitoring of their poultry flocks for signs of illness and taking steps to prevent wild birds from having contact with their flocks.
Newcastle disease has not yet been detected in Minnesota's poultry flocks. If birds show clinical signs suggestive of this disease, producers should immediately contact their veterinarian or the Board of Animal Health. Similarly, cormorants, gulls and pelicans suspected to have the disease should be reported to the local Department of Natural Resources (DNR) area wildlife office.
Cormorant and gull die-off occurred earlier this summer on Marsh Lake in Big Stone County and Wells Lake in Rice County and in recent days sick and dead cormorants have been discovered at Leech Lake in Cass County. Additionally, the National Wildlife Health Center is conducting tests on dead cormorants, gulls and pelicans collected from Lake Vermillion and Lake of the Woods. To date, all dead birds have tested negative for the avian influenza virus.
A viral avian disease, Newcastle rarely affects humans. When it does affect humans it generally causes a relatively mild pink eye.
Newcastle Disease is not new to Minnesota. The last virulent outbreak of this disease occurred in 2008, when about 2400 birds died at 8 different locations. State officials ensure that dead birds are buried or incinerated.

[Newcastle disease virus was suspected in an earlier post. So this
seems to provide some confirmation of the disease, and is not avian
influenza. Readers are referred to ProMED-mail 20100807.2692 for more
information on this disease. - Mod.TG]
