What’s Happening and How to Handle Produce Safely

If you’ve noticed more headlines about food poisoning lately, you’re not imagining it. The CDC and FDA are tracking a multistate outbreak of cyclosporiasis. It’s an intestinal illness caused by the parasite Cyclospora cayetanensis, and it’s linked to iceberg lettuce. Here’s what’s confirmed so far. And more importantly, here’s what you can do in your own kitchen to lower your risk.

What’s Happening

The CDC’s most recent update (August 13, 2026) ties the outbreak to Taylor Farms de Mexico iceberg lettuce. It has reached 6,358 illnesses across 15 states, with at least 278 hospitalizations. Two deaths were reported in Michigan, both involving people with significant underlying health conditions. Separately, CDC’s broader weekly surveillance shows a rise in domestically acquired cyclosporiasis cases nationwide since May 1, 2026, compared to the same period last year. Not all of those cases are tied to this specific outbreak.

Where the Outbreak Came From

Traceback and interview data point to iceberg lettuce processed by Taylor Farms de Mexico, a central Mexico-based supplier. Illnesses have been connected to lettuce sold at retail, including under the Marketside brand at Walmart. They’ve also been linked to lettuce served at Taco Bell locations across several states.

The Recall

Taylor Farms issued a voluntary recall of all iceberg lettuce sourced from central Mexico on July 17, 2026. The best-by dates on the recalled products have now passed. None of it should still be on shelves or in restaurant kitchens, but it’s a useful reminder to stay alert to future recalls.

Why the Case Count Keeps Climbing

Health officials note there’s roughly a six-week lag between when someone gets sick and when their case is confirmed and added to the official count. That means the case count is expected to keep rising for a while, even though the recalled product is long gone from the market. Health departments are also investigating whether other, unrelated Cyclospora clusters are contributing to this year’s overall increase.

This is a developing situation. For the most current numbers, check the CDC’s Cyclosporiasis outbreak page directly, since counts are updated weekly.

What Is Cyclosporiasis, Anyway?

Cyclospora is a microscopic parasite. It spreads through food or water contaminated with feces, usually via produce that was watered, washed, or handled with tainted water somewhere in the supply chain. Symptoms typically include:

• Watery diarrhea (often frequent)
• Loss of appetite and weight loss
• Stomach cramps and bloating
• Fatigue
• Low-grade fever, nausea

Symptoms can appear anywhere from a few days to over a week after exposure. Without treatment, illness can drag on for weeks or even months. It’s rarely life-threatening in otherwise healthy people, but it can hit harder in those with weakened immune systems or existing health conditions. If you’ve had unexplained, persistent diarrhea, it’s worth calling your doctor. A stool test is the only way to confirm Cyclospora.

How to Handle Produce Safely at Home

The unsettling part of this outbreak is that Cyclospora doesn’t always wash off easily, and it’s invisible to the naked eye. Here’s what actually helps.

Start With the Basics

1. Wash your hands first — every time. Before you touch any produce, wash your hands with soap and water for at least 20 seconds. This sounds obvious, but it’s one of the most-skipped steps in home kitchens.

2. Rinse produce under running water, even if you’re going to peel it. Bacteria and parasites on the outside of fruits and vegetables can transfer to the inside when you cut or peel them. Rinse everything under cool running water before prepping, including melons, avocados, and citrus.

3. Don’t rely on soap, bleach, or produce washes. The FDA doesn’t recommend washing produce with soap, detergent, or commercial produce washes. They aren’t proven safer than plain water, and they can leave residue behind. Plain running water and a gentle rub is the standard recommendation. Use a clean produce brush for firm items like potatoes or melons.

Go a Step Further

4. Know that washing alone can’t guarantee removal of Cyclospora. This is the uncomfortable truth about this particular parasite: it can resist washing. Cooking is the most reliable way to kill it. Heating produce to at least 158°F (70°C) will destroy the parasite. For high-risk situations, like feeding someone immunocompromised, consider cooking leafy greens and other produce rather than serving them raw.

5. Use separate cutting boards for produce and raw meat. Cross-contamination is one of the easiest mistakes to make. Keep one board for fruits and vegetables and a separate one for raw meat, poultry, and seafood.

6. Refrigerate promptly and check for cross-contamination in your fridge. Store produce away from raw meat, and keep your fridge at or below 40°F (4°C). Cyclospora doesn’t multiply outside a host. Still, a clean, well-organized fridge reduces the chance of other contamination.

Stay Ahead of Future Recalls

7. Stay current on recalls. Sign up for FDA or USDA recall alerts. Or check the FDA’s recall page periodically, especially for leafy greens, herbs, and berries. These are the produce categories most frequently linked to Cyclospora outbreaks.

8. When in doubt, throw it out. If you’re not sure whether produce in your fridge was part of a recall, it’s not worth the risk. Toss it.

The Bottom Line

Outbreaks like this one are unsettling. But they’re also a good reminder that a few consistent habits go a long way toward keeping your kitchen safe: washing your hands, rinsing produce under running water, keeping cutting boards separate, and paying attention to recalls. If you or a family member develops persistent watery diarrhea, don’t wait it out. Call your doctor and mention any recent exposure to iceberg lettuce or fast-food salads, since a simple stool test can confirm or rule out Cyclospora.
