28 September, 2018

As part of enhanced surveillance for virulent Newcastle disease virus in exhibition birds, the virus was detected in a live bird market. As a result, the USDA Animal and Plant Health Inspection Services (APHIS) and the California Department of Food and Agriculture (CDFA) are conducting a comprehensive epidemiological investigation of the event with enhanced surveillance. State officials have quarantined the affected premises and implemented movement controls. The market has been depopulated and cleaned and disinfected. Live bird markets in the area have been ordered to close for a day and perform cleaning and disinfection with environmental sampling. 
In 1971, a major outbreak occurred in commercial poultry flocks in Southern California, almost 12 million birds were destroyed. The eradication program cost $56 million.
In 2002-03 Newcastle disease outbreak, originally confirmed in backyard poultry in Southern California, spread to commercial poultry operations in California and backyard poultry in Arizona, Nevada and Texas.  The outbreak response led to the depopulation of 3.16 million birds at a cost of $161 million.
