From California Animal Health and Food Safety Laboratory System

We want all of our avian clients and stakeholders to be aware that Mexico has recently reported a case of Exotic Newcastle Disease (END) to the World Organization for Animal Health (OIE). The flock was located in Tijuana, just south of the U.S. border and has been depopulated. This report may be found at http://web.oie.int/wahis/public.php?page=single_report&pop=1&reportid=10244.

As END remains endemic (native to or prevalent) in Mexico, this finding is a good reminder that foreign animal diseases such as END or Avian Influenza may be introduced into California at any time. Veterinarians and bird owners are encouraged to submit sick birds to CAHFS immediately for diagnosis and to assist with rapid surveillance for foreign animal diseases. Poultry from small flock and backyard owners may be submitted to CAHFS at no charge. Immediate reporting of sick birds will help to prevent a major END outbreak, such as the one we experienced in 2002-03.

For additional information on END, please go the CDFA website at http://www.cdfa.ca.gov/ahfss and find the END link under “Quick Links.”

For additional information on laboratory submissions please go to the CAHFS website at http://www.cahfs.ucdavis.edu.

I was glad to see this already on BYC this morning. I was about to post it.

The University of Florida IFAS Extension has this to say about Newcastle Vaccination:

Chickens and turkeys can be immunized against Newcastle disease. Low-virulence live-virus vaccines are administered by a variety of routes such as drinking water, intraocular (eye drops), intranasal (nose drops), spray). Killed-virus oil emulsion vaccines are administered to pullets intramuscularly or subcutaneously as a final vaccine prior to the onset of egg production.

Chicks are often vaccinated at the hatchery against Newcastle disease and infectious bronchitis with a combination vaccine. Day-old poultry vaccinated for Newcastle disease can not be shipped through the mail.

The combination Newcastle-Infectious Bronchitis vaccine can also be given at 10-35 days. The vaccine can be administered via the drinking water, intraocular route or intranasal route. For breeder and layer flocks the vaccine needs to be repeated at 3-month intervals to maintain protective immunity. Alternatively, an inactivated vaccine can be given at the time of housing (18-20 weeks). Further vaccinations should not be required with this procedure. In breeder flocks, the high antibody level obtained by repeated vaccinations will assure transmission of a uniform parental immunity to offspring.

If you purchase pullets or mature chickens to add to your vaccinated flock, they can be vaccinated with Newcastle disease (B-1) vaccine via drinking water, intraocular or intranasal routes. The more reactive LaSota Newcastle disease vaccine is then given 4 weeks later.

Turkeys are often vaccinated against Newcastle disease at 4 weeks of age, and again when the breeders are housed.


So a simple vaccination at hatching would not be effective against the disease unless follow-up vaccinations are administered later.
 
I also just got this notice from CAHFS.

We need to remember to be diligent in cleaning our water dishes and to be on the lookout for sick wild birds.

Last year, cankor wiped out my wild doves and also 6 of my laying hens because my hens used a water source that was used by the sick doves.

Earlier this week I captured a sick bird on my property, and turned him into the Wildlife Rescue. It turns out he had a bacterial infection and within one day showed symptoms of wet pox. Again another illness that would have hit my flock.

Be on the lookout, know your birds and their behaviors, reduce your birds' stress and keep things clean.

Good Luck.
 
I know what you mean we can do all we can within our control when transporting birds and then wild birds bring it in. A lot of migratory birds winter in Mexico like doves. I used to feed them but decided years ago through education from the ODFW that I was doing more harm to them as a whole by feeding them.
