No new Newcastle infections reported

Federal and state officials are getting closer to declaring Nevada free of exotic Newcastle disease.

No cases of infection in Southern Nevada birds have been confirmed in a few weeks, but before officials can say the disease has been eradicated in the Silver State, further monitoring is necessary, said Dr. David Thain, state veterinarian.

The quarantine that took effect Jan. 16, after the infection was discovered in chickens near Nellis Air Force Base, remains in place.

"We have eliminated the risks of known infected or contaminated birds and materials spreading the disease to other areas," Thain said.

Once an area a little over a half-mile around the previously infected area is declared disease-free, fresh poultry will be introduced. The disease-free birds are known as sentinel birds, Thain said.

"If our sentinel birds remain healthy, then we can declare eradication," Thain said.

To date, nine citations have been issued for violating the quarantine. Ten investigations have been initiated.

Violators of the quarantine order could result in fines up to $600 and other civil penalties up to $25,000.

Owners can protect their poultry, racing pigeon flocks or pet birds by avoiding contact with infected birds, officials said.

Exotic Newcastle disease does not pose a risk to humans.
