The U.S. Centers for Disease Control and Prevention (CDC) reported seven more Cyclospora infections on Tuesday, boosting its outbreak total to 598. The number of affected states rose to 22, with the latest illness onset listed as July 31. In its latest update, CDC stated that most of the cases were reported from mid-June through mid-July. South Dakota and Wyoming are the two new states on the list, each with one illness. Texas, way out front in the number-one spot, reported 267 cases in its latest update, 20 more than CDC’s total for the Lone Star State. Adding those cases to the CDC total puts the national total at 618. Cyclospora cases in Iowa and Nebraska have been linked to a bagged lettuce mix from a producer in Mexico, but it’s still not clear if cases in other states are part of the same outbreak. At least 40 people have reportedly been hospitalized so far. On Aug. 12, FDA released information regarding the traceback investigation of Taylor Farms de Mexico salad mix and the company’s decision to suspend as of Aug. 9 “production and shipment of any salad mix, leafy green, or salad mix components from its operations in Mexico to the United States.”Cases in this outbreak are defined as laboratory-confirmed Cyclospora infection in a person with onset of illness since June 2013 and no history of travel outside of the U.S. or Canada during the 14 days prior to onset of illness. Cyclospora is a single-celled parasite that can cause diarrhea, vomiting and nausea several days to weeks after exposure. It is most commonly associated with imported fresh produce.
