Cyclospora Outbreak Linked to Iceberg Lettuce Spreads to More U.S. States

Health officials are warning that a cyclospora outbreak, potentially linked to iceberg lettuce, has been connected to more states. Cyclospora infections have been reported in at least 41 states this year, with investigators working to determine if additional states are part of the nine-state outbreak. Cyclosporiasis reports often have a lag due to the incubation period of symptoms and the time required for testing and investigations.
