US Expands Lettuce-Linked Cyclosporiasis Probe to 20 States as Cases Surpass 11,000

U.S. health authorities have expanded their investigation into a widespread cyclosporiasis outbreak linked to iceberg lettuce, adding three more states to the probe for a total of 20. The announcement was made Thursday by the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC).

Scope of the Outbreak

The ongoing outbreak, traced to iceberg lettuce from a Taylor Farms facility in central Mexico that was served at Taco Bell restaurants, is now one of the largest foodborne illness events in recent U.S. history. According to federal health agencies, the total number of cases has reached 11,458, which includes 495 hospitalizations.

Key details from the latest update include:

• The investigation has newly expanded to include Georgia, Tennessee, and Texas.
• Michigan remains the most severely affected state, reporting two related deaths in individuals with significant underlying health conditions.
• The Michigan health department separately reported 14,510 cases linked to the outbreak in the state, an increase of about 2% from its prior update.

Regulatory Action and Market Impact

The FDA stated it is continuing onsite inspections and product sampling at the lettuce farms and processing facility in Mexico, working in coordination with Mexican officials. The agency also expressed confidence that all recalled iceberg lettuce has been successfully removed from the market.

This significant outbreak has reportedly shaken consumer confidence in the fresh produce sector. Cyclosporiasis is an intestinal illness caused by the Cyclospora parasite, leading to symptoms such as diarrhea and nausea.
