Quick Take

✓

The Cyclospora outbreak has grown to **1,645 confirmed cases across 34 states**, with 5,100+ more under investigation — and 141 people hospitalized

✓

**Taco Bell is under investigation** — health officials are probing a possible connection, and some locations have already stopped serving lettuce and cilantro

✓

**Washing produce won't protect you** — Cyclospora resists the chlorine sanitizers used in processing, including on pre-washed bagged salads

✓

**Most doctors won't catch it** — you must specifically ask to be tested for Cyclospora by name; it's not part of a standard stool culture

✓

**Seniors face higher risk** — seek care promptly for prolonged diarrhea, dehydration, or symptoms that improve then return; it's treatable with the antibiotic Bactrim

This article was updated 7-17-2026 to include information about a confirmed Taco Bell connection and new CDC data. 

**UPDATED**: (from [CNN](https://www.cnn.com/2026/07/16/health/cyclospora-outbreak-shredded-lettuce?ref=smartseniordaily.com)) "​**Shredded iceberg** lettuce supplied by Taylor Farms and **sold at some Taco Bell** restaurants has been linked to a multistate outbreak of cyclosporiasis, a source familiar with the investigation said Thursday." 

****Taco Bell Statement**   
"Based on ongoing conversations with public health officials, and out of an abundance of caution, Taco Bell has taken immediate action to voluntarily remove potentially impacted lettuce from a supplier in select states. The affected ingredient from our supplier is being indefinitely removed from our supply chain nationwide and will be replaced within 24 hours in select states.  
  
While no official advisory has been issued, we believe public health is a shared responsibility among restaurants, their suppliers, and authorities, and we are proud to have consistently acted quickly and proactively to protect our guests. Taco Bell has taken precautionary action, and we encourage all relevant restaurants, retailers, and foodservice operators to do the same." Irvine, Calif. (Jul. 16, 2026)

## How Many People Are Affected

UPDATED: The Centers for Disease Control and Prevention (CDC) has [confirmed](https://www.cdc.gov/cyclosporiasis/php/surveillance/index.html?ref=smartseniordaily.com) cases in at least "**1,645 confirmed domestic cases of cyclosporiasis and is aware of more than 5,100 cases** that require further analysis to confirm the illness as domestically acquired cyclosporiasis."

The CDC said that **the outbreak has hit 34 states** and that multiple states have reported an increase in cases compared to the same period last year. The CDC said that a possible connection has been [identified](https://www.cdc.gov/cyclosporiasis/outbreaks/07-26/index.html?ref=smartseniordaily.com) in four states—Kentucky, Ohio, West Virginia, and Michigan.

That's the bad news; the good news is that of the 141 ​people hospitalized, no deaths have been reported. But that official count is almost certain to be an undercount—and it doesn't include a major new cluster that emerged after the data was collected.

## What Is Cyclospora — and Why Haven't I Heard of It?

Cyclosporiasis is a severe intestinal infection caused by the microscopic parasite *Cyclospora cayetanensis*. People typically catch it by **eating or drinking fresh produce or water contaminated with infected feces**. It frequently triggers **watery, sometimes explosive diarrhea, stomach cramps, nausea, vomiting, and profound fatigue.**

The tricky X factor is the timeline. **Once someone eats food contaminated by the parasite, it can sit there anywhere from two to 14 days before any symptom shows up.** And for those of us who can't remember what we had for breakfast yesterday, we could have absolutely no idea what you ate that caused you to be sick.

## Doctors are clueless, too 

**Reports** [**suggest**](https://www.medicaldaily.com/cyclospora-outbreak-145-cases-17-states-2026-summer-produce-alert-475832?ref=smartseniordaily.com) **that illness can be missed by doctors**, too, since cyclospora is not part of a standard stool culture, and most clinical labs do not routinely test for it unless it is specifically requested. 

This means **many (if not most) cases are never diagnosed**, leaving patients and their doctors scrambling for a reason behind the illness when a treatable parasitic infection is actually the cause.

## What Foods Are Suspect?

Unlike bird flu or salmonella or other foodborne illnesses, no one can point to a specific food product or any that have been recalled or publicly identified as the source of this outbreak. 

However, health officials have *previously* traced similar infections to items such as **cilantro, basil, raspberries, snow peas, mesclun lettuce (commonly** **sold in grocery stores as "spring mix"), and bagged salads**. 

## Clues are starting to appear, though

[**Dr. Wesley Long**](https://www.houstonmethodist.org/newsroom/could-your-salad-be-the-source-houston-methodist-pathologist-available-to-discuss-reported-parasite/?ref=smartseniordaily.com)**, medical director of diagnostic microbiology at Houston Methodist**, says the multi-state spread is a telling clue.

> "Historically, these outbreaks have often been associated with fresh produce such as herbs, leafy greens and berries," Dr. Long said. "Because cases are being reported across multiple states, investigators will likely focus on foods that were distributed nationally and may have become contaminated during harvesting, processing or packaging."

Herbs present a special challenge. 

> "Herbs can be particularly challenging to trace because they're frequently used as ingredients in prepared foods, sauces and restaurant dishes," Dr. Long said.

### Washing lettuce may not do anything

In similar situations, washing your produce may be enough, but not here. 

> "Cyclospora is resistant to the chlorine-based sanitizers commonly used in produce processing," Dr. Long said, "which means contaminated produce can sometimes reach consumers despite routine washing and sanitation measures."

## Why Seniors Need to Pay Extra Attention

Confirmed cases run the gamut—from age 5 to 86\. But it's seniors who could have a fight on their hands. Especially seniors who are immunocompromised—including **those managing diabetes, cancer, or autoimmune conditions or taking medications that suppress the immune system**. The CDC [says](https://www.cdc.gov/cyclosporiasis/php/surveillance/index.html?ref=smartseniordaily.com) that age group is more susceptible to prolonged or severe illness.

Things could take a detour if someone is dehydrated because older bodies are less efficient at retaining fluids. At an even greater risk are those who are already managing kidney or heart conditions that complicate fluid replacement.

But that's not the end of it. Reports [note](https://www.deseret.com/lifestyle/2026/07/01/cdc-investigating-multistate-parasite-outbreak-explosive-diarrhea-cyclosporiasis/?ref=smartseniordaily.com) that symptoms can disappear and reappear if the parasite is not treated, meaning seniors who feel better for a few days may not be out of the woods. 

## How Is It Treated?

Cyclosporiasis *is* treatable. The infection is **typically treated with the antibiotic combination trimethoprim-sulfamethoxazole (aka Bactrim)**, which the CDC says is highly effective. There is **no proven alternative treatment for people who cannot take sulfa drugs**.

## What You Should Do Right Now

Even though there are question marks all over this situation, the CDC and FDA have yet to issue a recall or advise avoiding any specific food. 

In the meantime, here's the practical guidance:

- **Wash all fresh produce thoroughly** under running water before eating, even pre-washed or bagged items. Keep in mind that washing alone cannot eliminate all risk.
- **Scrub firm produce** such as melons and cucumbers with a clean brush.
- **Tell your doctor specifically to test for Cyclospora** if you develop prolonged diarrhea after eating fresh greens, herbs, or salads. Don't assume a simple stool test will catch it because it won't unless your doctor orders it by name.
- **Seek care promptly** if you experience severe diarrhea, signs of dehydration (extreme thirst, dark urine, or dizziness), or symptoms that seem to improve then return.
