Cyclospora outbreaks continue to confound investigators

摘要

The source or sources of an outbreak of food-borne illnesses caused by Cyclospora continues to challenge federal and state investigators. As of Sept. 20, the Centers for Disease Control and Prevention said there have been 643 reports of Cyclospora infection from 25 states. Yet only those illnesses traced back to the states of Iowa and Nebraska have been linked to a source. Public health officials in Iowa and Nebraska performed investigations within their states and concluded that restaurant-associated cases of Cyclospora infection in the states were linked to a salad mix produced by Taylor Farms de Mexico, a business unit of Taylor Farms, Salinas, Calif. The C.D.C. said it is collaborating with the Texas Department of Health and Human Services to investigate cases of cyclosporiasis reported in the state.
