A multi-state Cyclospora outbreak that investigators are probing for links to certain Taco Bell locations has put leafy greens back under the microscope — and raised immediate choices for shoppers and diners. Health authorities say avoiding prewashed bagged mixes and handling whole heads of lettuce carefully can reduce the chance of infection while the probe continues.
Where the investigation stands
Federal and state public health agencies, including the CDC and the FDA, are tracing an uptick in Cyclospora infections that appears tied to fresh produce. Officials have not yet named a specific supplier or product, but interviews with people who became ill repeatedly point to salad greens as a common exposure; many also reported recent visits to Taco Bell locations now under review.

In response, the fast-food chain has voluntarily removed certain fresh ingredients from some outlets while investigators work to identify a source.
| Metric | Reported total |
|---|---|
| Confirmed Cyclospora cases since May 1 | 1,645 |
| Additional suspected reports under review | ~5,100 |
| Hospitalizations linked to the outbreak | 145 |
What Cyclospora does and who is at risk
Cyclospora cayetanensis is a microscopic parasite that infects the small intestine after ingestion of contaminated food or water. The most common symptom is watery diarrhea that can be prolonged; untreated cases sometimes last for weeks. People with weakened immune systems are at higher risk of severe or extended illness.
Health officials advise seeking medical care if diarrhea is severe, persistent, or accompanied by dehydration.
Practical food-safety steps from experts
Registered dietitian Caroline Margolis and public health experts recommend practical changes consumers can make now to lower their exposure risk.
- Avoid prewashed, bagged salad mixes; opt for whole heads of lettuce instead.
- Remove and discard the outer two to three leaves before using the head of lettuce.
- Rinse whole heads thoroughly under running water and dry before chopping or serving.
- Wash hands with soap and water before and after handling fresh produce.
- Consider frozen or canned fruits and vegetables as alternatives when extra caution is desired.
- If you become ill, stay hydrated and consult a clinician about testing and treatment.
One public health adviser noted that, while no single produce item has been confirmed in this outbreak, some experts currently recommend iceberg lettuce for those seeking a lower-risk option because it can be washed and trimmed as a whole head.
Simple pantry and recovery tips
Dietitians also emphasize that fresh produce remains an important part of a healthy diet. If you fall ill, choose gentle, nutrient-dense foods — such as bananas, cooked oats and plain yogurt or fermented dairy like kefir — to help restore hydration and calories during recovery.
Short-term steps shoppers can take at the store and at home:
- Buy whole produce rather than pre-cut items when possible.
- Refrigerate cut or cooked fruits and vegetables promptly (within two hours).
- Discard damaged or bruised portions before preparing food.
As the investigation continues, following these straightforward precautions can reduce personal risk without giving up the nutritional benefits of fruits and vegetables.
