Virginia’s Cyclospora Outbreak: What You Need to Know As Cases Near 250

When the summer heat rolled in, a microscopic parasite called cyclospora slipped onto the plates of many Virginians, turning salads into a dreaded affair. By early September the Virginia Department of Health reported somewhere between 50 and 199 confirmed cases, and the CDC’s national tally for the week ending Aug. 27 climbed to 11,458 across 20 states. Two people have even died – both in Michigan – underscoring how serious this seemingly‑harmless bug can be.

What triggered the frenzy? Iceberg lettuce from Taylor Farms de Mexico. In mid‑July the company recalled its product after sick diners linked their illness to Taco Bell meals that used the lettuce. The recall also swept up Marketside brand heads sold at Walmart. Since then the FDA says it’s “confident” every offending head is off shelves, and most of the “best‑by” dates have already passed.

That’s good news, but it’s not a full stop. Health officials haven’t declared the outbreak over. Instead they’re saying the risk level has dropped dramatically. “If you wanted to go out for a salad tonight, you’re pretty safe from cyclospora at this point,” noted Matthew Moore, a food‑science professor at UMass Amherst, speaking to CNN. Dr. Colleen Kraft of Emory University echoed the sentiment, distinguishing the specific recalled lettuce from iceberg lettuce as a whole.

Why did this parasite flare up now? Cyclospora thrives in warm, humid conditions – exactly the kind of weather we get from May through August. The parasite lives in microscopic amounts of human fecal matter that can hitch a ride on produce through contaminated irrigation water or agricultural runoff. When that water meets fresh lettuce, cabbage, raspberries, basil or any other leafy green, the parasite can settle into crevices that are hard to wash away.

That brings us to the ever‑popular question: How do you wash produce to keep cyclospora at bay? The FDA’s advice is practical, not fancy. First, peel away the outer two or three leaves of any leafy green. Then give the remaining leaves a thorough rinse under clean running water – no soap, no bleach, no commercial “produce washes.” Those chemicals either don’t reach the parasite or can be absorbed by the leaves, making matters worse.

For harder produce – think cucumbers, melons, carrots – scrub with a clean produce brush. Berries and delicate herbs should be swished gently under running water; soaking just spreads any contaminant around. And remember, pre‑washed or “ready‑to‑eat” packages aren’t a free pass – commercial washes aren’t guaranteed to kill cyclospora.

If you really want to be sure, heat does the trick. Cooking vegetables to at least 158 °F (70 °C) will destroy the parasite. Of course, most people eat lettuce raw, so the best bet is diligent hand‑washing before and after handling any produce, discarding bruised spots, and refrigerating cut or peeled items within two hours.

Beyond Virginia, the outbreak now spans a long list of states – Arkansas, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Massachusetts, Michigan, Missouri, Nebraska, New Hampshire, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas, and West Virginia. The CDC warns the true number of infections is probably higher than reported, because many people recover without ever seeing a doctor.

What can you do right now? Keep an eye on any fresh‑produce recalls, practice the simple washing steps above, and don’t panic about iceberg lettuce in general. The specific batch that sparked the crisis is gone, and the supply chain has been tightened. As the summer season winds down, the cyclospora numbers are already slipping, offering a sigh of relief for families who love their crisp salads.

Stay tuned to local health department updates and the CDC’s website for the latest numbers. And, as always, if you develop sudden, “explosive” diarrhea that lasts more than a few days, seek medical care – early diagnosis can make treatment smoother.
