Nearly 12,000 Americans across 41 states have been infected with Cyclospora cayetanensis — a microscopic intestinal parasite that causes explosive diarrhea, nausea, and weight loss — traced to iceberg lettuce grown in central Mexico and shipped across the border by a single supplier: Taylor Farms de Mexico.
The FDA increased border screening after the recall.
The numbers here are staggering. Michigan alone accounts for 8,176 confirmed or probable cases and 160 hospitalizations. Ohio has logged over 2,500. Indiana and Illinois are each approaching 600. Nationally, at least 308 people have been hospitalized. The CDC's own investigation page, updated July 24, confirms 1,947 laboratory-confirmed infections tied specifically to a nine-state Taco Bell cluster spanning Indiana, Kentucky, Michigan, Ohio, West Virginia, Illinois, Kansas, Oklahoma, and Pennsylvania.
The contaminated product? Shredded iceberg lettuce served at Taco Bell locations and sold under Walmart's Marketside brand — the Marketside Iceberg Salad in 12-ounce and 24-ounce bags, and Marketside Shredded Lettuce in 8-ounce and 16-ounce bags, with best-if-used dates between July 18 and August 3. Twenty-seven states received the recalled products. Taylor Farms issued a voluntary recall on July 17, pulling all iceberg lettuce sourced from central Mexico off the U.S. market.
By July 17, the damage was already done. The CDC launched its initial outbreak investigation on July 14, when cases had already topped 400 across four states. Illness onset dates range from June 22 through July 20 — meaning Americans were eating contaminated lettuce for nearly a month before anyone pulled the trigger on a recall. Of 190 people interviewed by investigators, 90 percent reported eating iceberg lettuce. The FDA's traceback investigation converged on a single supplier.
One supplier. One country of origin. Nearly 12,000 infections.
The CDC's deputy director offered this reassurance: "We anticipate continuing to see cases increase, possibly through the end of August." Good to know. The parasite has already spread to 41 states, but at least someone at the CDC is keeping a calendar.
North Carolina is now investigating fresh parsley and cilantro as additional suspected sources — which tracks with history. Past Cyclospora outbreaks in the U.S. have been linked to salad greens, cilantro, basil, raspberries, green onions, and snow peas. The parasite isn't new. The import pipeline that keeps delivering it is the problem.
We spend a lot of time talking about what crosses the southern border illegally. Here's something that crossed legally, through an FDA-monitored supply chain, stamped and approved and shipped to your local Walmart and Taco Bell — and it's sent nearly 12,000 people to the bathroom and 308 to the hospital. The system that was supposed to catch this didn't catch it. The agency responsible for food safety screening at the border ramped up inspections after the outbreak, not before. The recall came weeks after the first infections.
Cooking lettuce to 158 degrees kills the parasite. Of course, no one cooks lettuce. That's the point.
The FDA screens imports from Mexico. Taylor Farms de Mexico ships lettuce from central Mexico to restaurants and grocery stores in at least 27 states. The lettuce arrived with a parasite. The system didn't flag it. Twelve thousand Americans got sick.
That's not a food safety system. That's a rubber stamp with a government logo.
