US Health Agencies Expand Lettuce-Linked Cyclosporiasis Probe to 20 States

U.S. health authorities have expanded their investigation into a widespread cyclosporiasis outbreak linked to iceberg lettuce from central Mexico, adding three more states to the probe. The U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) confirmed on Thursday that the investigation now covers a total of 20 states.

Scope of the Outbreak

The outbreak, traced to iceberg lettuce served at Taco Bell restaurants and supplied by Taylor Farms' operations in Mexico, is one of the largest foodborne illness events in recent U.S. history. According to the federal agencies, the number of reported cases has grown significantly.

Key figures from the latest update include:

• 11,458 total confirmed cases of cyclosporiasis.
• 495 hospitalizations related to the illness.
• 3 new states added to the investigation: Georgia, Tennessee, and Texas.

Michigan has been the most severely affected state, reporting two deaths associated with the outbreak. Officials noted that both individuals had significant underlying health conditions.

Regulatory Action and Market Impact

The FDA stated it is continuing to conduct onsite inspections and product sampling at iceberg lettuce farms and a processing facility in Mexico, coordinating its efforts with Mexican authorities. The agency expressed confidence that all recalled lettuce has been successfully removed from the market.

This large-scale outbreak has shaken U.S. consumer confidence in the fresh produce category. Cyclosporiasis is an intestinal illness that can cause severe diarrhea, nausea, and other gastrointestinal symptoms, posing a risk to public health and creating potential liability and supply chain disruptions for the companies involved.
