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.

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 to WSDA's Pest Program and, if possible, include a photo.

The U.S. Department of Agriculture’s (USDA) Foreign Animal Disease Diagnostic Laboratory has confirmed African swine fever (ASF) in samples collected from pigs in the Dominican Republic through an existing cooperative surveillance program. USDA’s Animal and Plant Health Inspection Service (APHIS) has numerous interlocking safeguards in place to prevent ASF from entering the United States. Pork and pork products from the Dominican Republic are currently prohibited entry as a result of existing classical swine fever restrictions.
The USDA continues to work diligently with partners including the Department of Homeland Security’s Customs and Border Protection (CBP) and the U.S. swine industry to prevent ASF from entering the United States. ASF is not a threat to human health, cannot be transmitted from pigs to humans and it is not a food safety issue.
