Last year, the TVA found water hyacinth in a slough near Scottsboro. TVA quickly partnered with the State of Alabama, bringing experts from both sides to start addressing the invasive water weed. Water hyacinth is bad news for Guntersville and other great fisheries in the Tennessee Valley. The plant can quickly outcompete other beneficial plants, often creating biological wastelands. Hartis and his team are asking the public to be on the lookout for hyacinth this summer. “If you see a [hyacinth] plant, pull it out of the water immediately and put it in the trash. We don’t want plants to float to a new area and establish a new colony.” If you find a large area of hyacinth, please report it to TVA's Public Land Information Center at (800) 882-5263 (between 8 a.m. and 6 p.m. Eastern).

Key partners and contributors in Napa County, California, recently celebrated and recognized the critical safeguarding accomplishment achieved together, of eradicating the invasive European grapevine moth (EGVM) from the U.S. The keys to success were early detection, our rapid response, and a strong collaboration between federal, state and local officials, growers, university scientists and extension services. Such partnerships remain critical to our ability to safeguard agriculture and facilitate safe trade.

On September 12, USDA’s Animal and Plant Health Inspection Service (APHIS) and its partners declared Monroe Township in Clermont County, Ohio, free of Asian longhorned beetle (ALB). This news came just months after APHIS declared Stonelick Township free of the beetle in March. ALB was first discovered in Monroe Township in August 2011. We think people unknowingly moved the beetle in firewood from Tate Township before anyone knew about the infestation there. Before long, adult beetles emerged and started infesting trees in Monroe. To stop this pest in its tracks, APHIS and state officials had to remove 1,186 trees in Monroe. They protected 4,614 other trees by injecting a pesticide directly into the trunks. It took 7 years, but after inspecting over 177,000 trees, APHIS and its partners finally confirmed the beetle is no longer there.

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.
