USDA and Partners Work to Eliminate Invasive Nutria From Maryland's Eastern Shore (Jul 2, 2018)
USDA. Blog.
Maryland’s eastern shore has seen thousands of acres of protective marshland impacted by the nutria's destructive feeding habits. To protect the valuable resources of Maryland’s Chesapeake Bay, The Chesapeake Bay Nutria Eradication Project (CBNEP) began in 2002 to permanently remove invasive nutria from the marshes of the Delmarva Peninsula and to protect, enhance, and restore the aquatic and river ecosystems they damaged.
USDA Confirms Virulent Newcastle Disease in Backyard Exhibition Birds in Utah, Not a Food Safety Concern (Jan 29, 2019)
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.
White-Nose Syndrome and Mammoth Cave
DOI. NPS. Mammoth Cave National Park.
Bats are dying. Please help us protect them. A disease called white-nose syndrome (WNS) is spreading through the eastern United States, killing bat populations. White-nose syndrome is considered to be present in the Mammoth Cave System. It is believed that humans may contribute to the spread of white-nose syndrome by visiting contaminated caves or mines and then wearing the same clothing or carrying the same objects to unaffected caves or mines, transporting spores from one place to the other. You can help us save bats by following a few simple guidelines.
