Cyclospora: Public Health – Seattle King County Issues Update
Officials say the national outbreak spans multiple states, but King County has not seen an unexpected rise in cyclosporiasis cases.
- Public Health- Seattle & King County reports no local spike in Cyclospora cases, despite a national outbreak affecting Michigan, Ohio, and New York.
- Cyclospora is a microscopic parasite that spreads through contaminated food or water, not person-to-person like Norovirus, and symptoms can persist for weeks or longer.
- Public Health is not recommending changes to shopping routines since the national outbreak source remains unconfirmed. Vigorously washing produce helps, though heating food to 158°F is most effective at killing the parasite.
- Older adults, pregnant individuals, and those with weakened immune systems face greater risk for serious illness and should cook produce to reduce infection risk.
- Most residents diagnosed with Cyclospora annually were exposed during international travel, though Public Health Insider notes a small number of cases typically originate from local sources each year.
