Massive Cyclosporiasis Outbreak Officially Linked to Four More States

Nine separate states now officially have related, confirmed cases of serious diarrheal illness specifically caused by the microscopic cyclospora parasite and largely thought to be directly linked with common iceberg lettuce, according to the latest data from the US Centers for Disease Control and Prevention.

Four more affected states — Illinois, Kansas, Oklahoma, and Pennsylvania — have just been formally added to the expanding outbreak that already notably includes Indiana, Kentucky, Michigan, Ohio, and West Virginia.

The newly additional states were notably first publicly reported by The Washington Post.

Ongoing health data continues to strongly show that heavily contaminated iceberg lettuce originally sourced from Taylor Farms de Mexico directly made these people severely sick, the CDC firmly said. The health agency has already officially tallied a staggering 1,947 people confirmed infected with cyclospora who also specifically reported recently eating at Taco Bell within the nine affected states. Confirmed illnesses in this massive outbreak closely tied to the iceberg lettuce first officially began on June 22 and have aggressively continued straight through July 20, the CDC explicitly said.

But local health departments operating in these nine specific states have actually reported well more than 12,000 total cases of cyclosporiasis entirely this summer alone, with the vast, overwhelming majority of those cases unfortunately situated in Michigan.

Michigan health officials have repeatedly stated it’s highly possible that some of their numerous cases are actually linked to completely additional, separate sources. Understandably, not absolutely everyone they’ve rigorously interviewed could clearly remember recently eating any lettuce.

Detailed, lengthy interviews with affected patients and extensive traceback information have successfully helped public health officials quickly home in directly on iceberg lettuce heavily imported from central Mexico as the highly likely primary source. Federal investigators with the US Food and Drug Administration, carefully working as well as health authorities down in Mexico, are actively investigating exactly what specific factors may have directly caused the dangerous contamination. Taylor Farms has quickly recalled massive shipments of shredded lettuce recently processed in central Mexico that was widely shipped to restaurants, large food services, and numerous retailers across 27 different states.

Cyclosporiasis cases have unfortunately been rapidly identified in literally dozens of states throughout this hot summer, and the federal CDC has publicly said it’s currently investigating several separate clusters, and not absolutely all of them are directly linked to the exact same source.

The overall total number of confirmed cyclosporiasis cases actively reported this specific year in the US is also significantly higher than usual averages. There were well more than 4,500 total cases in 2023 and slightly more than 3,500 total cases in 2024, officially according to federal health officials. But there have already quickly been thousands more officially reported this year, with at least a full month still left in the traditional risk season.

It can often take up to two full weeks for noticeable symptoms of cyclosporiasis to actually appear after unwittingly consuming contaminated food or water. Classic symptoms typically include severe watery diarrhea, sudden loss of appetite, noticeable weight loss, painful cramping, intense bloating and vastly increased gas, severe nausea, and deep fatigue, and the unfortunate people who become significantly ill may actively suffer from these draining symptoms for several weeks.
