Foodborne Illness

Cyclospora: Two new cases of cyclosporiasis were reported in Montana the week of July 20th. These are the first domestically acquired cases reported to DPHHS in 2026. These two cases are not known to be linked to a multi-state outbreak. However, DPHHS is closely monitoring the multiple Cyclospora clusters in the United States currently under investigation by public health officials. Of these two new Montana cases, one was exposed while traveling out of state. The second case may have been exposed during travel to another state, but exposures in Montana could not be ruled out. A thorough investigation of both cases is ongoing. No recalled food items have been found in Montana at this time.
Cyclospora cases and outbreaks are often linked to consuming fresh produce. To reduce your risk:
- Discard outer layers of fruits and vegetables when possible, such as the outer two or three layers of leafy greens.
- Rinse produce thoroughly under clean running water.
- Cook produce to a temperature of at least 158°F, when cooking is an option.
- Consider purchasing locally sourced produce.
- As always, wash hands with soap and water for at least 20 seconds before and after handling food.
- Call your doctor if you have symptoms of Cyclospora, which can include watery diarrhea, fatigue, and loss of appetite.
