Cyclospora cayetanensis is a single-celled parasite that causes an intestinal infection called cyclosporiasis.
As of September 13, 2013 (5pm EDT), CDC has been notified of 642 ill persons with of Cyclospora infection from 25 states: Arkansas, California, Connecticut, Florida, Georgia, Illinois, Iowa, Kansas, Louisiana, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New York (including New York City), Ohio, Pennsylvania, South Dakota, Tennessee, Texas, Virginia, Wisconsin, and Wyoming.
Most of the illness onset dates have ranged from mid-June through mid-July.
Among 578 ill persons with available information, 45 (8%) have reported being hospitalized. No deaths have been reported.
Public health officials in Iowa and Nebraska performed investigations within their states and concluded that restaurant-associated cases of Cyclospora infection in their states were linked to a salad mix produced by Taylor Farms de Mexico.
On August 12, 2013, Taylor Farms de Mexico informed FDA that the company had voluntarily suspended production and shipment of any salad mix, leafy green, or salad mix components from its operations in Mexico to the United States.
On August 25, 2013, Taylor Farms de Mexico, with FDA concurrence, resumed production and shipment of salad mix, leafy greens, and salad mix components to the United States.
Currently, CDC is collaborating with the Texas Department of Health and Human Services and local public health departments to investigate cases of cyclosporiasis reported among people in Texas.
The preliminary analysis of results from an investigation into a cluster of cases that ate at a Texas restaurant does not show a connection to Taylor Farms de Mexico. This investigation is ongoing.
Although the investigation of cases continues, available evidence suggests that not all of the cases of cyclosporiasis in the various states are directly related to each other.
