### A Public Health Crisis Continues to Grow

Just when it seemed like the cyclospora outbreak might be peaking, federal health officials have confirmed that the outbreak is still expanding. On August 27, 2026, the FDA announced that three more states—**Georgia, Tennessee, and Texas**—have been linked to the outbreak, bringing the total to **20 states** .

The number of confirmed cases has climbed to **11,458**, up from roughly 10,900 the previous week . This is already the largest cyclosporiasis outbreak in U.S. history, surpassing the previous record of about 4,700 cases in 2019 . Nationwide, the CDC has reported approximately **17,180 confirmed cases** and **922 hospitalizations** from cyclospora this year .

**Two deaths have been reported in Michigan**, the hardest-hit state. Both individuals had "significant underlying health conditions," according to Michigan health officials .

### The Source: Taylor Farms de Mexico

The investigation has focused on iceberg lettuce grown at a farm in central Mexico operated by **Taylor Farms de Mexico** . Taylor Farms, a major U.S. produce supplier based in California, voluntarily recalled all iceberg lettuce sourced from the region on July 17, 2026 .

The recalled products were distributed to **27 states** and sold under multiple brand names, including Walmart's Marketside brand, and were also supplied to restaurants including Taco Bell . The CDC initially warned consumers to avoid eating shredded lettuce from Taco Bell locations in five Midwestern states, and the chain has since removed the affected lettuce from its supply chain nationwide .

The FDA has now classified the recalled lettuce at the **highest possible risk level**, reflecting the severity of the public health threat . FDA and CDC officials have initiated on-site inspections and sampling at Taylor Farms de Mexico's processing plant in Guanajuato, about 185 miles northwest of Mexico City .

### What Is Cyclospora?

Cyclospora is a microscopic parasite that infects the small intestine and causes a gastrointestinal illness called cyclosporiasis . The parasite is typically transmitted through food or water contaminated with feces—most commonly when produce is irrigated or washed with contaminated water .

**Common symptoms include:**

- Watery diarrhea, often "frequent and sometimes explosive" 

- Loss of appetite

- Abdominal cramps and bloating

- Nausea and fatigue

- Low-grade fever

- Weight loss

Symptoms typically appear **one to two weeks** after exposure, and the illness can last for weeks or even months without treatment. Unlike some other foodborne illnesses, cyclospora is **not** typically transmitted from person to person . Outbreaks tend to occur most often in late spring and summer.

### What You Should Do

1. **Check your fridge.** If you have iceberg lettuce sourced from Mexico—especially Taylor Farms products—throw it away immediately .

2. **Don't eat recalled products.** Even if you bought the lettuce at a grocery store, it could be part of the recall. The recalled products have "best by" dates through August 3, 2026 .

3. **Wash your produce thoroughly.** Cyclospora is resistant to many common sanitizers. Scrubbing produce under running water is essential, though cooking vegetables to 158°F is the only sure way to kill the parasite.

4. **Watch for symptoms.** If you develop watery diarrhea, abdominal cramps, nausea, or fatigue, contact your healthcare provider and ask to be tested for Cyclospora.

5. **Stay informed.** The FDA and CDC continue their investigations, and the situation remains fluid.
