FDA Apologizes for False Positive on Taylor Farms Lettuce, Still Links It to Cyclospora Outbreak
Anonymous
Key Points
1
The FDA said the positive test was limited to one shipment of iceberg lettuce from Taylor Farms de Mexico; the agency still links shredded iceberg lettuce from central Mexico to the outbreak and will continue traceback and market removals.
2
Former FDA Commissioner Scott Gottlieb stated that the false‑positive laboratory result does not clear Taylor Farms, noting that investigators rely primarily on epidemiological evidence to draw conclusions about the outbreak.
3
Michigan has reported 6,148 cyclosporiasis cases with 102 hospitalizations linked to the outbreak.
4
Consumer traffic data show a notable drop in fast‑food footfall, with Taco Bell down by 18.9% on a representative Friday (Chipotle down 6.9% and Cava down 4.2%), reflecting consumer reaction to the outbreak.

The outbreak has been linked to Taco Bell–related products across Indiana, Kentucky, Michigan, Ohio and West Virginia, with around 100 hospitalizations reported in connection to cyclosporiasis from Taco Bell–associated lettuce.
The FDA has retracted a lab test that showed Cyclospora contamination in shredded iceberg lettuce from Taylor Farms de Mexico, calling it a false positive. But the agency still links the company's central-Mexico lettuce to a multi-state outbreak that has sickened thousands, according to Daily Herald.
Michigan alone has reported 6,148 cases of cyclosporiasis and 102 hospitalizations. The outbreak has been tied to Taco Bell and other fast-food chains across Indiana, Kentucky, Michigan, Ohio, and West Virginia, according to Daily Herald.
FDA Retracts Test But Stands by Outbreak Link
The FDA reviewed the original lab result and concluded it was a false positive. As of July 19, there are no confirmed Cyclospora-positive lettuce samples from Taylor Farms. The FDA apologized to Taylor Farms for the error, according to LA Mag.
Even so, the FDA has not cleared Taylor Farms. The agency says epidemiological evidence — data tracking who got sick and what they ate — still points to shredded iceberg lettuce from the company's central Mexico facility. Traceback work and market removals will continue, Daily Herald reported.
False Positive Does Not Clear Taylor Farms, Experts Say
Former FDA Commissioner Scott Gottlieb weighed in quickly after the retraction. He said the false-positive lab result does not mean Taylor Farms is off the hook. Investigators rely mainly on epidemiological evidence — not just lab tests — to find an outbreak source, according to NY Post.
The FDA also pushed back on reports that it had issued a formal apology. The agency said it still believes the parasite came from Taylor Farms in Mexico, NY Post reported. A precautionary recall of central-Mexico iceberg lettuce remains in place. Other Taylor Farms products are not involved.
Taco Bell Traffic Drops as Consumers Avoid Fast Food
The outbreak has spooked fast-food customers. Consumer traffic data show Taco Bell foot traffic fell 18.9% on a representative Friday during the outbreak. Chipotle dropped 6.9% and Cava fell 4.2%. The numbers reflect how quickly a food-safety scare can hit restaurant chains.
The outbreak has been connected to Taco Bell-related lettuce products across five states. Around 100 hospitalizations have been reported in connection with cyclosporiasis tied to Taco Bell-associated lettuce, according to Daily Herald.
Pittsburgh Cases Steady While Michigan Numbers Keep Rising
Not every region is seeing the same surge. Pittsburgh's Allegheny County has reported just 11 cases and one hospitalization. Cases there have stayed flat while states like Michigan and Ohio continue to see sharp increases, according to Kansas.com.
Cyclospora cayetanensis is a microscopic parasite that causes an intestinal illness with explosive diarrhea, cramping, and fatigue. It spreads through contaminated food or water, not person to person. Authorities say they will keep updating the public as the investigation moves forward, Kansas.com reported.
