A Multistate Outbreak Linked to Taco Bell
Public health officials are investigating a multistate outbreak of cyclosporiasis tied to shredded iceberg lettuce served at Taco Bell restaurants. The infections have surfaced across Indiana, Kentucky, Michigan, Ohio, and West Virginia. According to the Centers for Disease Control and Prevention (CDC), the outbreak has resulted in 1,644 laboratory-confirmed infections and 94 hospitalizations. Fortunately, no deaths have been reported in connection with this specific event.
Tracing the Contaminated Supply Chain
The U.S. Food and Drug Administration (FDA) launched a traceback investigation to pinpoint the source of the contaminated produce. Investigators successfully determined that the affected Taco Bell locations received shredded iceberg lettuce from a single supplier based in Mexico.
The CDC emphasizes that this outbreak is isolated to this specific supply chain. Shredded iceberg lettuce purchased at grocery stores or served at other restaurant chains is not included in this alert. The agency notes that the current case count reflects only those illnesses that are laboratory-confirmed and explicitly linked to the identified product, rather than all cases of cyclosporiasis reported nationwide.
The Biology of Cyclospora Infection
Infection occurs when a person consumes food or water contaminated with the parasite.
Symptoms typically appear about one week after exposure.
Medical Guidance for Affected Consumers
If you have recently consumed shredded iceberg lettuce at a Taco Bell in the five affected states and are experiencing symptoms, the CDC advises contacting a healthcare provider. Because Cyclospora is not detected in standard stool culture tests, patients should specifically request that their provider order a test for Cyclospora.
Patients are also encouraged to maintain adequate hydration while symptomatic. If you have questions regarding cases in your specific state, the CDC recommends contacting your local state health department.
