Cyclospora Cases Rise, but Iowa Stays Safe

The parasite cyclospora is driving a rapid increase in stomach illnesses nationwide, with over 4,000 reported cases spanning 34 states. In Iowa alone, health officials have tallied 57 infections by mid‑July 2026, primarily linked to international travel. None of these Iowa cases tie back to the broader outbreak or a specific food source, according to state statements.

Symptoms and Timeline

• Severe diarrhea
• Abdominal cramps
• Nausea
• Fatigue

Symptoms typically appear 2 to 14 days after exposure.

National Impact

• Michigan: >4,300 cases
• Clusters also noted in Ohio, West Virginia, and Kentucky—all hinting at a common origin.
• While the exact source remains uncertain, Michigan officials suspect lettuce may be involved.

Prevention Tips

• Wash hands thoroughly before handling produce.
• Rinse all fruits and vegetables under running water.
• Use a clean brush on firm items like cucumbers.
• Remove any bruised parts.
• Refrigerate cut or cooked produce immediately.
• If produce is pre‑washed, no additional washing is needed at home.

The CDC has issued warnings to doctors and public health workers about the escalating outbreak. Stay vigilant, practice good hygiene, and keep an eye on food sourcing to protect yourself from cyclospora.
