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 Los Angeles County, California. It is important to note that the presence of the disease is not a food safety concern. This is the first case of virulent Newcastle disease, previously referred to as exotic Newcastle disease, in the U.S. since 2003.
