Summer is usually the season for fresh salads, vibrant fruit bowls, and farm-to-table greens. But after this year’s cyclosporiasis outbreak, many of us are second-guessing that bagged lettuce in the fridge. If you are searching for the foods to avoid during the cyclospora outbreak, you certainly aren’t alone. Public health concern was high, and many people changed their grocery lists and kitchen habits to keep their families safe.
Update: CDC’s final update (September 11, 2026) says the 2026 outbreak linked to Taylor Farms de Mexico iceberg lettuce has ended. The product was recalled on July 17 and is no longer sold. Here is what you need to know about this stubborn summer parasite, the highest-risk produce items, and how to lower your risk.
What Exactly Is Cyclosporiasis?
Cyclosporiasis is a foodborne intestinal illness caused by Cyclospora cayetanensis, a microscopic parasite. Unlike common bacterial infections like Salmonella or E. coli, Cyclospora is a complex parasite that spreads when people consume food or water contaminated with infected human feces—often through agricultural irrigation water or infected farm workers.
If you ingest the parasite, symptoms typically hit anywhere from two to 14 days later. The hallmark symptom? Loud, watery, and often explosive diarrhea. This is usually paired with extreme fatigue, stomach cramps, bloating, and nausea. Illness can last from several days to a month or longer.

The Main Foods to Avoid During the Cyclospora Outbreak
Because Cyclospora relies on a human host and specific environmental conditions, it tends to cling to fresh, raw produce. Based on historical data and public health warnings, the primary foods to avoid during the cyclospora outbreak include:
-
Bagged Salads and Pre-Washed Greens: Iceberg lettuce (linked to the 2026 outbreak) and mesclun mixes.
-
Fresh Berries: Raspberries have been linked to past outbreaks.
-
Fresh Herbs: Cilantro, basil, and parsley.
-
Snow Peas and Sweet Peas.
Why Washing Your Produce Isn’t Enough
You might be thinking, “Can’t I just scrub my vegetables really well?” Unfortunately, no. While washing produce under running water is a great standard food safety practice, it isn’t a silver bullet against Cyclospora.
The surface of leafy greens and berries is highly textured and full of microscopic crevices. According to the CDC, washing cannot guarantee that the parasite is removed.
How Cooking Produce Lowers Your Risk
So, if washing doesn’t guarantee safety, what can you do? Heat is the answer.
Cooking produce to an internal temperature of at least 158°F (70°C) inactivates the Cyclospora parasite, so cooked vegetables are a safer choice than raw ones when Cyclospora is a concern.
Delicious Alternatives to Raw Greens
You don’t have to give up your summer vegetables; you just have to change how you prepare them. If you want to steer clear of the foods to avoid during the cyclospora outbreak, try swapping them for these heat-treated favorites:
Fire up the grill: Swap raw side salads for grilled zucchini, charred corn on the cob, or grilled asparagus.
Roast your veggies: Roasted Brussels sprouts or broccoli florets tossed in olive oil make incredibly safe, highly nutritious sides.
Sauté your greens: If you’re craving leafy greens, opt for heavily sautéed spinach or kale instead of a raw salad.

What to Do If You Experience Symptoms
If you recently consumed high-risk produce and start experiencing severe digestive distress and fatigue, see a healthcare provider if symptoms are severe or persist. Most healthy people recover without treatment, but illness can last days to a month or longer.
Head to your healthcare provider and specifically ask for a stool test. If the lab detects C. cayetanensis, the CDC says the treatment of choice is the antibiotic combination trimethoprim/sulfamethoxazole (TMP-SMX); azithromycin and doxycycline are ineffective. Your provider may also recommend plenty of fluids to replace what you lose.
Stay informed, keep your kitchen thermometer handy, and when in doubt—cook it out!
