A parasite that had not been seen in the Pacific Northwest before is now turning up in the region. The so-called fox tapeworm has been detected in Pullman, in eastern Washington, prompting a public health warning.
The concern is what it can do to people. The fox tapeworm is capable of causing severe illness in humans, making its arrival in the area a matter health officials are taking seriously.
The route of infection is easy to overlook. Humans can become infected by working with soil that has been contaminated with the feces of foxes or coyotes, where the parasite's eggs can be present.
Researchers believe it may already be more widespread than it appears. A veterinarian and pathologist at Washington State University said there is likely more of the parasite in the environment than people realize.
That uncertainty is why experts are stressing caution. The same specialist said awareness and basic precautions are the best forms of prevention against the parasite.
The recommended steps are simple. Health experts advise wearing gloves when cleaning areas where animal feces could be present, and washing hands thoroughly afterward.
For now, the focus is on limiting exposure. As the parasite appears to be establishing itself in the region, officials are urging people who work with soil or around wildlife to stay mindful of the risk and take steps to protect themselves.
