Cyclospora outbreaks with no confirmed sources grow: FDA

Big surge this summer: nearly 14,000 domestically acquired cyclospora cases reported in the U.S., and the true number is likely higher.
The outbreak tied to iceberg lettuce has expanded to more states, and so far that's the only one with an identified source.
Multiple other cyclospora investigations are still active — symptoms can take weeks to appear, so see a doctor if diarrhea persists.
