Lettuce Linked to Big Diarrhea Outbreak

A recent health investigation suggests that lettuce and other salad greens might be the culprit behind a sudden surge in cyclosporiasis, a severe diarrheal disease.

What the Investigation Reveals

• Michigan Health Officials first flagged lettuce during early reviews, noting its frequent appearance in the data.
• The Michigan Department of Health and Human Services is still gathering evidence; other foods remain possible sources.
• No specific farmer or distributor has been named, keeping the search open.

National Impact

• Total cases reported: > 800 across 31 states.
• Under investigation: > 1,500 cases.
• Hospitalizations: 86 patients.
• Deaths: None reported.

Prevention Tips

1. Choose Whole Heads of Lettuce
   
   • Avoid pre‑washed bags when possible.
2. Trim and Wash Thoroughly
   
   • Remove outer leaves; wash inner leaves carefully.
3. Cook or Peel Produce
   
   • If feasible, cook greens or peel fruits before consumption.
4. Rinse All Fresh Produce
   
   • Give all fresh fruits and vegetables a good rinse before eating.

Historical Context

Past outbreaks have involved:

• Bagged salad mixes
• Fresh cilantro, basil
• Raspberries

These patterns underscore that ready‑to‑eat greens can carry the parasite responsible for cyclosporiasis.
