USDA's Animal and Plant Health Inspection Service (APHIS) confirmed the presence of virulent Newcastle disease in a commercial chicken flock in Riverside County, California. This finding is part of an outbreak in southern California that began in May 2018 in backyard exhibition birds. This is the first case in commercial poultry since 2003.

Virulent Newcastle disease is not a food safety concern.  No human cases of Newcastle disease have ever occurred from eating poultry products.

Secretary Perdue is making available an additional $45 million to the Animal and Plant Health Inspection Service (APHIS) and its partners to address the ongoing virulent Newcastle disease (vND) outbreak in southern California.  This funding will allow APHIS and the California Department of Food and Agriculture (CDFA) to strengthen their joint efforts to stop the spread of this disease and prevent it from affecting additional commercial flocks.  vND has been confirmed in more than 435 backyard flocks since May 2018.  It was also confirmed in four commercial flocks in December 2018 and January 2019.

The goal of this report is to capture the current state of knowledge on the use of fire as a tool to manage invasive plants in wildlands. By providing a more thorough source of information on this topic, we hope this review facilitates improved decision making when considering the use of prescribed burning for the management of invasive plants.
