Cyclospora Outbreak Sickens 1,600, FDA Retracts Positive Test

The U.S. Food and Drug Administration retracted an earlier positive test result for the parasite on Taylor Farms lettuce, but said the company remains the focus of the investigation.

The outbreak has spread to 27 states, with consumers turning to farmers markets amid the scare.

Lawsuits have been filed against the supplier and restaurants, alleging negligence.

Health officials continue to trace the source of the contamination, which causes prolonged gastrointestinal illness.
