The Idaho Department of Agriculture (ISDA) has confirmed the presence of quagga mussel in the Mid-Snake River. Quagga mussel larvae was first detected in the Snake River near Twin Falls on September 18, 2023, by routine monitoring conducted by the ISDA. If nothing were done, quagga mussels would quickly take over waterways. They would irreparably harm water use in Idaho. These findings mark the first time a rapid response plan has been put into action for quagga mussels in Idaho.
ARS works with foreign scientists to prevent overseas diseases from spreading to the United States. This collaboration specifically targets research that cannot be conducted in the U.S., either because a disease does not exist here or the expertise in a pathogen resides overseas. Of particular concern are emerging diseases that may spread from animals to infect humans.

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.
