Cyclosporiasis Outbreak Expands to Three New States, Surpassing 11,000 Cases

Federal health officials confirmed on August 28 that a cyclosporiasis outbreak tied to contaminated produce has now reached 20 states after adding Georgia, Tennessee and Texas to the list. The Food and Drug Administration reported 11,458 illnesses in total, marking one of the largest foodborne events in recent U.S. history. The cases trace back to iceberg lettuce supplied by Taylor Farms de Mexico for use at Taco Bell locations, with illnesses first surfacing in July.

Timeline of the Spread

The outbreak began gaining attention in early summer when clusters appeared in several states. By mid-July the FDA had already linked dozens of cases to specific restaurant supply chains. Updates continued through August, with the agency adding three states in its latest announcement one week after the prior report.

Michigan remains the hardest-hit area, accounting for two deaths among individuals who had significant underlying health conditions. Health regulators continue to monitor new reports as the investigation proceeds. The pattern shows steady growth rather than a sudden spike, reflecting the time it takes for symptoms to appear and for cases to be confirmed through laboratory testing.

Business and Consumer Ripple Effects

The scale of the outbreak has prompted measurable shifts in how Americans purchase and consume fresh produce. Sales of leafy greens dropped as much as 30 percent in the early weeks, while overall vegetable sales fell 16 to 17 percent and fruit purchases also declined. Industry leaders note that these changes reflect altered shopping patterns that extend beyond the immediate crisis.

Dave Ciesinski, president and CEO of The Marzetti Company, told FOX Business that consumers are adjusting their routines in lasting ways. The episode has affected not only lettuce suppliers but also related product categories such as salad dressings and prepared meals. Restaurants and retailers have faced both direct supply disruptions and broader questions about sourcing practices for imported produce.

Public Health Response and Ongoing Risks

Cyclospora is a single-celled parasite that can produce stomach cramps, nausea, fatigue and weight loss, though some people experience no symptoms at all. The Centers for Disease Control and Prevention notes that illness typically starts about one week after exposure and may last from several days to a month, sometimes recurring. Hundreds of hospitalizations have been recorded nationwide.

Authorities have focused on tracing the contaminated lettuce through the supply chain and advising consumers on safe handling of fresh produce. The FDA and state partners continue to investigate additional sources and distribution points. Public messaging emphasizes that thorough washing of fruits and vegetables remains an important step, even as the primary source in this outbreak has been identified.

The episode underscores how quickly a single contaminated ingredient can affect a wide population and how supply-chain transparency matters for both public health and commercial stability.
