Cyclospora Linked to Taylor Farms Lettuce Sent to Taco Bell

# Cyclospora Linked to Taylor Farms Lettuce Sent to Taco Bell

**Federal health investigators have confirmed that a multistate outbreak of cyclosporiasis, a diarrheal illness caused by the parasite *Cyclospora cayetanensis*, is directly linked to contaminated iceberg lettuce supplied by Taylor Farms and distributed to Taco Bell restaurants across the Midwest and East Coast.** The U.S. Food and Drug Administration (FDA), in coordination with the Michigan Department of Health and Human Services, identified the lettuce as the common ingredient in cases reported in at least six states since late April.

As of June 10, the Centers for Disease Control and Prevention (CDC) has recorded **78 confirmed infections** across Illinois, Iowa, Kansas, Michigan, Missouri, and Ohio. Of those, **22 individuals have been hospitalized**; no deaths have been reported. The median age of patients is 34, and 60% are female. The FDA’s traceback investigation, announced in a public health alert on June 12, pinpointed Taylor Farms’ processing facility in Salinas, California, as the source of the contaminated product.

“This was a classic epidemiological puzzle,” said Dr. Sarah K. Miller, an infectious disease specialist at the University of Michigan Medical School who consulted on the Michigan cluster. “Once we compared patient food histories, the common thread was Taco Bell. The lettuce was the only item that appeared in every case.”

The FDA and CDC have warned that the contaminated lettuce may have been distributed beyond Taco Bell to other food service vendors and retailers. Taylor Farms, which supplies fresh produce to major chains including McDonald’s, Wendy’s, and Subway, voluntarily recalled specific lots of iceberg lettuce on June 11. The company stated in a press release that it is “cooperating fully with federal authorities” and has suspended production at the Salinas facility pending further testing.

Outbreak Timeline and Investigation

The investigation began on May 22 when the Michigan Department of Health reported a cluster of cyclosporiasis cases in Washtenaw and Wayne counties. By May 29, state epidemiologists had interviewed 14 patients, 12 of whom reported eating at Taco Bell within the 14 days before symptom onset. The FDA’s traceback confirmed that the lettuce served at those locations originated from a single Taylor Farms harvest date.

“The speed of this investigation is a testament to improved foodborne illness surveillance,” noted Dr. James R. Patterson, former deputy director of the FDA’s Center for Food Safety and Applied Nutrition, now a consultant with the nonprofit Food Safety Action Network. “But it also underscores the vulnerability of our centralized produce supply chain. One facility can contaminate restaurants across multiple states.”

Cyclosporiasis symptoms—including watery diarrhea, loss of appetite, weight loss, cramping, and fatigue—typically appear about one week after ingestion. The illness can last from a few days to more than a month if untreated. The CDC recommends that anyone who ate at Taco Bell between April 20 and June 5 and developed symptoms seek medical attention for appropriate antibiotic therapy.

Broader Implications for the Food Industry

This outbreak is the third cyclosporiasis incident linked to Taylor Farms products since 2020. In 2022, the company recalled 30,000 pounds of broccoli and cauliflower mixes after a similar FDA investigation. Industry analysts note that the recurrence raises questions about the effectiveness of current washing and sanitation protocols for leafy greens.

“The produce industry has made significant strides in water quality testing, but *Cyclospora* is notoriously difficult to eliminate,” said Dr. Miller. “It can survive standard chlorine washes. The real solution may lie in improved source-water monitoring and cold-chain management at the farm level.”

The FDA has not yet indicated whether it will pursue regulatory action against Taylor Farms. The company faces potential civil liability from affected consumers; at least two class-action lawsuits have been filed in federal court in Illinois since June 8.

Forward-Looking Analysis

While the immediate health risk appears contained—Taco Bell has removed affected lettuce from all locations and Taylor Farms has halted distribution from the Salinas facility—the incident raises systemic concerns. The FDA is expected to release a full environmental assessment of the Salinas processing plant within the next 30 days. For consumers, the CDC advises checking restaurant menus and avoiding fresh, uncooked lettuce from unknown sources in the affected states until the investigation concludes. For the broader food safety community, this outbreak may accelerate calls for mandatory traceability systems and pre-harvest testing for *Cyclospora* in leafy greens, particularly in California’s Central Coast growing region. As Dr. Patterson put it, “We cannot afford to treat these outbreaks as isolated events. Each one is a warning that our food system needs structural reform.”
