The U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) officially concluded an investigation into a massive multistate outbreak of Cyclospora infections linked to recalled shredded iceberg lettuce supplied by Taylor Farms de Mexico.
Cyclospora cayetanensis is a microscopic parasite that contaminates food or water via human feces, causing severe watery diarrhea and gastrointestinal illness. While the CDC declared the active outbreak over in mid-September, the final FDA traceback and testing report details were finalized.
Outbreak At a Glance
- Pathogen: Cyclospora (Parasite)
- Vehicle: Shredded Iceberg Lettuce from Taylor Farms de Mexico
- Total Cases: 12,883 laboratory-confirmed illnesses
- Hospitalizations: 570
- Deaths: 2
- Scope: Impacted 21 states across the U.S. (with product distribution reaching at least 31 states and parts of Mexico).
Final Investigation Findings
According to the final updates from the FDA Investigation Announcement, inspectors conducted comprehensive onsite testing of water, soil, and sediment in Mexico.
- Environmental Matches: Two environmental samples tested positive for Cyclospora—one from a wastewater tank at the Taylor Farms de Mexico processing plant, and another from an agricultural drainage ditch at an associated lettuce farm.
- Recall Status: A voluntary recall was initiated by Taylor Fresh Foods. The FDA confirms that all contaminated products have long passed their shelf life and are entirely off the market.
Symptoms and Treatment
For those affected, Cyclospora causes cyclosporiasis, which includes explosive watery diarrhea, loss of appetite, weight loss, stomach cramps, bloating, nausea, and fatigue. Unlike bacterial food poisoning, it is a parasite and typically requires specific antibiotic treatment.
