The U.S. Food and Drug Administration is investigating a new cyclospora outbreak that has sickened 72 people and is unrelated to a separate, massive outbreak linked to contaminated lettuce.
The newly identified outbreak was added to the FDA’s active foodborne illness investigations list on Wednesday. The source of the contamination remains unknown as federal investigators conduct traceback operations to identify where the parasite originated.
Separate From Lettuce Crisis
The FDA is currently managing six active cyclospora investigations. The largest involves iceberg lettuce from Taylor Farms branded products sourced from central Mexico, which has resulted in more than 4,000 laboratory-confirmed cases across 41 states, with an additional 7,400 suspected cases pending confirmation.
The lettuce outbreak has been traced to a specific source despite a false-positive test result reported over the weekend. At least five states were directly affected, though recalled products reached dozens of states nationwide.
Why Detection Remains Challenging
Cyclospora symptoms can emerge anywhere from two to 14 days after exposure, complicating outbreak investigations.
