Federal health officials are investigating a significant surge in cyclospora cases in the U.S. as reported in 2026. The Food and Drug Administration (FDA) has announced a newly identified outbreak affecting 72 individuals, yet the food source remains unidentified.
Ongoing Cyclospora Outbreaks
The FDA’s announcement follows a recent federal investigation linking a separate outbreak to shredded iceberg lettuce supplied by Taylor Farms de Mexico. This outbreak affected Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia.
Since May 1, the Centers for Disease Control and Prevention (CDC) has reported over 4,000 confirmed cases across 41 states. Additionally, there are more than 7,000 pending reports. State-level totals might differ as they include both confirmed and probable cases. A CDC lag assumption of six weeks exists between illness onset and case reporting.
Impact on States
Michigan reports the highest number of cases with 7,171, including 102 hospitalizations. Ohio follows with over 2,200 cases and numerous hospitalizations. Other states such as Indiana and New York have also reported hundreds of cases. The outbreak’s true extent likely exceeds reported figures, as many recover without medical care and remain undiagnosed.
New Outbreak Under Investigation
The FDA is investigating a new outbreak affecting 72 people. Despite Health and Human Services Secretary Robert F. Kennedy Jr.’s statement about controlling the major outbreak linked to lettuce, investigations continue. The FDA is assessing whether other products, retailers, or channels could be related to the illnesses. The specific states involved in the latest outbreak are unidentified.
Five-State Outbreak Linked
Federal officials confirmed shredded iceberg lettuce at Taco Bell in five states as a source. Following this, Taylor Farms voluntarily recalled all such lettuce from central Mexico. Concerns about food safety led Taylor Farms to express their worry for affected individuals and families.
Consumer Actions
Taco Bell is now selling $1, lettuce-free Enchiritos. This offering includes a flour tortilla with ground beef, beans, onions, cheese, and red sauce. The item is temporary, and availability duration is unspecified.
Understanding Cyclosporiasis
Cyclosporiasis is an intestinal illness caused by the Cyclospora cayetanensis parasite. Symptoms usually emerge a week after exposure. Diarrhea, stomach cramps, nausea, and fatigue typify this illness. Without treatment, symptoms can persist long-term, with recurrent diarrhea. People experiencing symptoms should consult healthcare providers for testing.
Federal officials advise thorough washing of fruits and vegetables, with added caution for pre-packaged items. Cooking produce at 158 degrees Fahrenheit (70 degrees Celsius) effectively kills the parasite. With an illness mean age of 44, cases range from those aged 2 to 95.
Authorities continue to seek connections between the recently reported 72 cases and potential additional sources or channels. Consumers should remain vigilant as developments unfold.
