California virulent Newcastle Disease update: Field Biosecurity Guidelines

July 16, 2019

July 16, 2019. There have been no cases identified since June 4, 2019. All poultry farm inspections and service provider visits continue to be prohibited except for public health reasons. Heightened biosecurity will remain in place through October 1, 2019.

On May 21, 2019 the California Department of Food and Agriculture and the United States Department of Agriculture distributed an information letter about the Virulent Newcastle Disease eradication program to residents in the program area. See attached file.

On May 8, Dr. Jones released Field Biosecurity Guidelines for State/County/City Personnel Entering Shell Egg Packing Facilities, Poultry Harvest Facilities, and Poultry Farms. State, county, city, and private inspectors, auditors and service providers were requested to suspend all on-farm poultry area visits, and to replace on-site inspections with remote, record-based audits. Commercial poultry producers have been asked to minimize personnel entering live production areas.

On March 22, Dr. Annette Jones, the California State Veterinarian, issued a Poultry Disease Biosecurity Advisory recommending that all poultry be housed indoors and separated from wild birds, particularly migrating waterfowl. This heightened biosecurity advisory will remain in place through July 1, 2019, when an updated risk evaluation will be conducted.

On Feb 27, Dr. Jones enlarged the Southern California quarantine area to further restrict bird movement. The quarantine mandates the reporting of sick birds and prohibits poultry owners from moving birds in all of Los Angeles County, and in large areas of San Bernardino and Riverside counties.The quarantine also requires bird owners to allow diagnostic testing, to isolate poultry from other species, to cease exhibitions, to stop the shipping and receiving of birds, and to enhance biosecurity. Fairs are being cancelled and many veterinary clinics are excluding sick birds.

As of April 11, $72 million of government funds have been spent or allocated. Backyard flocks depopulated have been compensated in the amount of $1.9 million and commercial flocks $3 million. 300 state and federal workers have now been deployed.
