On Sunday, July 19, Taylor Farms announced that the FDA had made a mistake, and a Taylor Farms sample that had tested positive for cyclospora was a “false positive.”

According to the CDC, symptoms include:
Less common symptoms may include:
Cyclosporiasis can be treated with a combination antibiotic, Trimethoprim-sulfamethoxazole. Most people recover without treatment.
Patients who suspect cyclosporiasis should ask medical staff to test for it, as it is not routine.
Cooking or cleaning produce carefully can lower the risk of infection. Clean produce with clean water and dry it.
