Oregon Reports Two Cyclospora Cases Tied to National Lettuce Outbreak

Two Oregonians have confirmed cases of Cyclospora infections that may be linked to the ongoing multistate cyclosporiasis outbreak that federal health agencies are investigating and that is caused by contaminated lettuce.

The Oregon Health Authority (OHA) confirmed that the cyclosporiasis cases are linked to the national outbreak. Both individuals traveled to other states involved in the recent nationwide recall of pre-shredded iceberg lettuce associated with the outbreak.

The products were not reported to have been distributed in Oregon and were voluntarily recalled on July 17.

The risk to the public remains low, and Cyclospora is not spread directly from person to person. Despite the national outbreak, Oregon has not detected an unusual increase in the number of cyclosporiasis cases. Cyclosporiasis is reported in Oregon each year (not typically linked to a national outbreak) and most cases report recent international travel.

Cyclosporiasis cases reported in Oregon:

• So far in 2026: 23
• 2025: 26
• 2024: 30
• 10 cases in 2023, eight cases in 2022, and 14 cases in 2021.

Additional cases among people who recently traveled to affected areas may still be reported. Reduce the risk of foodborne infections by following safe food handling practices. This includes:

• Washing hands and surfaces often,
• Rinsing fresh produce thoroughly under running water before eating or preparing,
• Cooking foods to proper temperatures.

OHA is not reporting demographic information about Oregon’s Cyclospora cases, including age, gender, or counties of residence, to protect their confidentiality.
