USDA. Animal and Plant Health Inspection Service.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is seeking feedback on its proposed list of pests and diseases of concern that are likely to pose a high risk to U.S. agricultural and natural resources.

Section 12203 of the 2018 Farm Bill requires pest- and disease-planning activities that mirror the extensive planning efforts APHIS already performs. Specifically, it requires APHIS to develop a uniform list of pests and diseases that represent the gravest threat to the United States and to develop comprehensive response plans to ensure Federal and State governments are prepared to respond to them.

See Animal and Plant Diseases and Pests of Concern for more information. The agency will review comments from the public about the list, including suggestions of pests or diseases that should be added or removed. In providing comments, individuals should keep in mind that the Farm Bill definition of a pest or disease of concern limits this list to those that are “likely to pose a significant risk to the food and agricultural critical infrastructure sector” and is not meant to be an exhaustive list of all possible pests or diseases. Comments may be submitted to APHISPestDiseaseList@usda.gov.

University of Arizona; USDA. Animal and Plant Health Inspection Service; Arizona Department of Agriculture.

This list of the most serious biotic pests and pathogens is maintained by the State (Arizona Department of Agriculture) and Federal (USDA) regulatory agents. Their goal is to prevent the introduction and/or spread of these pests/pathogens in our state.

USDA. APHIS. Cooperative Agricultural Pest Survey (CAPS).

The National CAPS Committee will revise the National Pest Surveillance Guidelines when annually reviewing the policy, strategy, and performance of the CAPS program. The NCC also will approve annually a “Priority Pest List.” This list will include the Commodity and Taxonomic Survey Pests, as well as Pests of Economic and Environmental Importance (OPEP Prioritized List). The Priority Pest List will be based on input by PPQ, the States, Center for Plant Health Science and Technology (CPHST), National Identification Services (NIS), and commodity organizations.

Maryland Department of Agriculture.

The Maryland Department of Agriculture has confirmed that a single adult spotted lanternfly has been found on a trap in the northeast corner of Cecil County near the border of Pennsylvania and Delaware. This is the first confirmed sighting of the invasive species in Maryland, and the department does not believe there is an established population of the pest in the state. If you suspect you have found a spotted lantern fly egg mass, nymph, or adult, snap a picture of it, collect it, put it in a plastic bag, freeze it, and report it to the Maryland Department of Agriculture at DontBug.MD@maryland.gov.

University of Minnesota Extension.

This past August, a new population of golden clams, Corbicula fluminea, was discovered by twelve-year-old budding conservationist, William Guthrie. The new infestation was found in Briggs Lake (Sherburne County). The discovery of golden clams in Briggs Lake is significant because it is an inland lake with no supplemental heat source. If the clams can survive our winter months, they could also spread and reproduce in additional lakes and rivers. Similar to zebra mussels, infestations of golden clams can clog water intake pipes and alter local ecosystems.

Georgia Department of Natural Resources. Wildlife Resources Division.

The Georgia Department of Natural Resources' Wildlife Resources Division confirmed someone found a northern snakehead in early October in a pond on private property in Gwinnett County, marking the first time the invasive fish has been found in the state. Fishermen who find a northern snakehead should take pictures, note where it was caught and then report it.

Washington State Department of Agriculture.

Asian giant hornet is the world's largest species of hornet. In December 2019, WSDA received and verified four reports of Asian giant hornet near Blaine and Bellingham. These are the first-ever sighting in the U.S. Canada had also discovered Asian giant hornet in two locations in British Columbia in the fall of 2019. If it becomes established, this hornet will have serious negative impacts on the environment, economy, and public health of Washington State. If you think you may have spotted an Asian giant hornet, report it using the Hornet Watch Report Form.

Government of British Columbia. Ministry of Agriculture.

Three Asian Hornets (Vespa mandarinia) were found in the Nanaimo area on Vancouver Island in mid-August. The identification has been confirmed by Canadian and international experts. This is the first time this insect has been found in British Columbia. Please report suspected Asian giant hornet sightings to the Invasive Species Council of British Columbia.

USDA. Animal and Plant Health Inspection Service.
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.

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.

USDA. Animal and Plant Health Inspection Service.

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 of Newcastle disease have ever occurred from eating poultry products.

Virginia Tech.

Virginia Tech researchers who helped identify the dangerous Giant Hogweed plants in Clarke County, Virginia, want residents to stay on the lookout for the plant with toxic sap that can cause severe burns — but also stressed that the weeds are believed to have been planted intentionally decades ago and haven’t spread in the years since. Anyone who suspects they have found Giant Hogweed should take photos, check online to compare the plant to giant hogweed photos, and then contact a Virginia Cooperative Extension agent.
