Cyclospora Outbreak Linked to Recalled Lettuce: What Families Should Do

CDC and FDA say they are investigating a multistate Cyclospora outbreak linked to iceberg lettuce from Taylor Farms de Mexico—and they are warning people not to eat the recalled product.

If you or someone in your household ate shredded iceberg lettuce covered by the recall, the practical next step is symptom monitoring and calling a healthcare provider if symptoms start.

Many people who become infected develop watery diarrhea and may also have loss of appetite, fatigue, and weight loss. Symptoms usually begin about 1 week after exposure, but timing can vary—often from 2 days to 2 weeks or more.

What CDC and FDA are saying right now

CDC reports an outbreak investigation that is open and linked to iceberg lettuce in 9 states. CDC says Taylor Farms initiated a recall on July 17, 2026 for iceberg lettuce sourced from central Mexico.

Do not eat recalled iceberg lettuce. If you purchased recalled lettuce, CDC advises you to throw it away or return it.

If you ate the recalled lettuce, here’s what to do

1) Stop using the recalled product

If you have recalled lettuce in your home, do not eat it. CDC says to throw it away or return it.

CDC also advises washing items and surfaces that may have touched the recalled lettuce using hot, soapy water (or using a dishwasher).

2) Monitor for symptoms—especially prolonged watery diarrhea

CDC says symptoms of cyclosporiasis commonly include watery diarrhea, fatigue, and loss of appetite. Without treatment, symptoms can last a few days to a month or longer, and can follow a remitting-relapsing course (symptoms may improve and then come back).

3) If symptoms start, call your clinician and mention Cyclospora

Clinicians generally evaluate prolonged or relapsing diarrhea using a combination of history (like recent food exposures) and the right kind of targeted testing when infection is suspected.

CDC says you may need to specifically request Cyclospora testing because routine stool tests do not always screen for this parasite.

What to say (plain-language script):

“My household ate recalled Taylor Farms de Mexico iceberg lettuce. I have watery diarrhea.”
“Can we specifically test for Cyclospora?”

CDC’s Health Alert Network notice to clinicians also emphasizes that lab detection can be challenging and that clinicians should request Cyclospora testing on stool specimens. It notes that molecular (PCR-based) testing may improve detection where available.

Home care priorities (what you can do while you’re monitoring)

CDC and FDA emphasize that if you develop symptoms, the immediate priority is to stay well-hydrated, especially if diarrhea is frequent.

If symptoms are severe, not improving, or you’re caring for a child, older adult, pregnant person, or someone with a weakened immune system, consider contacting a clinician sooner rather than waiting.

Prevention going forward: reduce risk until guidance changes

Wash hands and fresh produce thoroughly under running water before eating, cutting, or cooking.
Know the limits of washing: CDC notes that washing alone cannot guarantee removal of Cyclospora.
If you cook produce: CDC says cooking can kill the parasite—aim for at least 158°F (70°C) for produce that will be cooked.
Check for updates from CDC and FDA as the outbreak investigation continues.

What’s still uncertain

CDC says the outbreak investigation is open and it is also investigating other cyclosporiasis outbreaks and illnesses that are unrelated to this lettuce-associated cluster.

CDC also notes that cyclosporiasis can be underdiagnosed and underreported, meaning the confirmed counts may not reflect the full picture.

Quick checklist

Did your household buy recall-covered iceberg lettuce? Throw it away or return it.
Clean up: wash touched items and surfaces with hot soapy water (or run through the dishwasher).
Watch for symptoms: watery diarrhea and related symptoms can start about a week after exposure, but the window can be wider.
If symptoms start: contact your clinician and ask whether Cyclospora testing should be specifically requested.
