Notes from the Field: Tularemia Associated with Harbor Seal Necropsy - Kitsap County, Washington, October 2023

What is already known about this topic? Tularemia is a zoonotic disease caused by Francisella tularensis, a bacterium found in several animal species, most frequently occurring in rabbits and rodents. What is added by this report? In 2023, tularemia occurred in a wildlife volunteer after exposure to a deceased, infected harbor seal, the first known report of tularemia acquired through contact with a marine mammal, and the first detection of F. tularensis in a marine mammal. What are the implications for public health practice? Health care providers, public health investigators, and persons working with marine wildlife need to be aware of the potential risk for tularemia and other zoonotic diseases associated with harbor seal contact and adhere to established safety protocols.
