Virulent Newcastle disease, formerly known as exotic Newcastle disease, is a contagious and fatal viral disease affecting the respiratory, nervous and digestive systems of birds and poultry.  The disease is so virulent that many birds and poultry die without showing any clinical signs.

February 4, 2019: Two additional ranches with egg laying hens have been confirmed positive for vND. The first is a small ranch in San Bernardino County that was confirmed on January 22, 2019.  The hens have been euthanized.   The second is a larger commercial facility in Riverside County that was confirmed positive on February 1, 2019. These findings are part of the vND outbreak that began May 2018 in backyard birds. For a list of cases visit the USDA website at: https://www.aphis.usda.gov/animalhealth/vnd By moving quickly, to humanely euthanize affected flocks, we are eradicating the disease to prevent further spread and unnecessary suffering of these birds that would otherwise die from the virus.  … Read More

AETIOLOGY Classification of the causative agent Newcastle disease (ND) is a member of the family Paramyxoviridae in the genus Avulavirus. There are ten serotypes of avian paramyxoviruses designated APMV-I to APMV-10 and ND virus (NDV) has been designated APMV-1. NDV has also been categorised into five pathotypes based on clinical signs in infected chickens, designated: a) viscerotropic velogenic, b) neurotropic velogenic, c) mesogenic, d) lentogenic or respiratory and e) aymptomatic. Pathotype groupings are rarely clear-cut.  Temperature:  Inactivated by 56°C/3 hours or 60°C/30 minutes. pH:  Inactivated by acid pH ≤ 2. Chemicals/Disinfectants:  Ether sensitive; inactivated by formalin, phenolics and oxidising agents (e.g. Virkon®); chlorhexidine, sodium hypochlorite (6%). Survival:                              Survives for… Read More

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the presence of virulent Newcastle disease in a small flock of backyard exhibition chickens in Utah County, Utah. This is the first case of virulent Newcastle disease in Utah.  This case is believed to be connected to the current outbreak of virulent Newcastle disease in California, as three of the birds at the premises were recently moved to Utah from Los Angeles County, California.  Since May 2018, 299 cases of Newcastle disease have been confirmed in Southern California, primarily in backyard exhibition birds. Virulent Newcastle disease is not a food safety concern.  No human cases… Read More
