The U.S. Centers for Disease Control and Prevention (CDC) has declared an end to a widespread cyclosporiasis outbreak that affected tens of thousands of people across 21 states between May and August, primarily in the Midwest and on the East Coast. The CDC recorded 12,883 laboratory-confirmed cases, resulting in 570 hospitalizations and two deaths. Although the number of recent infections has significantly declined, investigations into the cause remain ongoing; processed iceberg lettuce from Taylor Farms linked to the outbreak was removed from stores after a voluntary recall in mid-July.

The California Department of Public Health said the high number of cyclosporiasis cases in the state could be attributed to:
- An increased awareness of the illness due to national attention on the outbreak, leading to an increase in testing
- Overall improvements to the department’s surveillance and data-collection methods
- An increase in cases in people who traveled to areas with outbreaks, whether international or domestic
Food safety experts said identifying the source of a foodborne illness such as cyclosporiasis is a challenge because public health investigators need to analyze multiple pieces of evidence from available public health data, follow a potential food source through the supply chain and test samples of potentially contaminated food.
