An outbreak of cyclosporiasis has infected at least 1,700 people across more than half of U.S. states. The source is often hidden in everyday grocery salads. How can you protect yourself from this severe stomach bug? Three actionable steps can reduce your risk.
The illness is caused by the Cyclospora cayetanensis parasite. Outbreaks typically spike in late spring and summer. Contaminated fresh produce—especially salad greens, herbs, and berries—imported from tropical regions is a common vehicle. The CDC and FDA have linked cases to grocery store salad mixes.
Common symptoms include watery diarrhea, often explosive. Loss of appetite, weight loss, stomach cramps, bloating, nausea, and fatigue are also typical. Symptoms appear 1–2 weeks after exposure and can last for weeks if untreated. People with weakened immune systems face higher risk for severe illness. Seek medical care if diarrhea persists or dehydration occurs.
Step 1: Wash and Handle Your Grocery Produce Correctly
Washing produce reduces but does not eliminate Cyclospora. The parasite can be inside the leaves. Scrub firm produce under running water. For leafy greens, soak in a vinegar-water solution (1 part vinegar to 3 parts water) for 10 minutes, then rinse. Cooking kills the parasite. Consider cooking greens if you are in a high-risk group.
Step 2: Know Which Grocery Items Are High-Risk Right Now
Based on outbreak data, specific items are implicated: bagged salads, cilantro, basil, snow peas, and pre-cut fruit mixes. Check FDA recall alerts and store notices. Buy whole heads of lettuce instead of pre-cut mixes. Thoroughly wash each leaf. Freezing produce for 24 hours may help reduce risk, though it is not fully reliable.
Step 3: Build Kitchen Hygiene Habits That Block Cross-Contamination
Wash hands with warm soapy water for at least 20 seconds before and after handling produce. Use separate cutting boards for produce and raw meat. Sanitize countertops with diluted bleach or hydrogen peroxide. Avoid storing produce near raw meat juices. Cyclospora can survive on surfaces for days.
If you suspect infection, see a healthcare provider immediately. Ask for a stool test specifically for Cyclospora—standard O&P tests often miss it. Treatment is a course of trimethoprim-sulfamethoxazole (Bactrim). Over-the-counter anti-diarrheal meds can worsen symptoms by trapping the parasite. Hydration and electrolyte replacement are critical.
Frequently Asked Questions
- Can I get cyclosporiasis from restaurant salads? Yes, if the restaurant uses contaminated produce.
- Is the outbreak linked to a specific brand? Investigations are ongoing; check CDC updates.
- Can I rely on organic produce? No—organic produce can also carry Cyclospora.
- Does washing with soap work? No. Soap is not recommended for produce. Use water only, plus optional vinegar soak.
💡 Frequently Asked Questions (FAQ)
- Q: What is cyclosporiasis and how is it spread?
- A: Cyclosporiasis is an intestinal illness caused by the Cyclospora cayetanensis parasite. It spreads through ingestion of contaminated food or water, with outbreaks commonly linked to fresh produce like salad greens, herbs, and berries imported from tropical regions.
- Q: How can I protect myself from cyclosporiasis during the 2025 outbreak?
- A: Three key steps: 1) Wash produce thoroughly, soaking leafy greens in a vinegar-water solution; 2) Avoid high-risk items like bagged salads, cilantro, and pre-cut fruit currently implicated in outbreak data; 3) Cook produce thoroughly, as heat kills the parasite.
