Avoiding food or water that may have been contaminated with feces is the best way to prevent cyclosporiasis. Treatment with chlorine or iodine is unlikely to kill Cyclospora oocysts. No vaccine for cyclosporiasis is available.

The U.S. Food and Drug Administration’s (FDA) Center for Food Safety and Applied Nutrition (CFSAN) publishes detailed food safety recommendations for growers and suppliers. In its Guide to Minimize Microbial Food Safety Hazards for Fresh Fruits and Vegetables, CFSAN describes good agricultural practices (GAPs) and good manufacturing practices (GMPs) for fresh fruits and vegetables. The guidelines address the growing, harvesting, sorting, packaging, and storage processes that, if followed, can reduce the overall risk for microbial contamination during these steps. The exact manner in which Cyclospora oocysts become attached to produce is not fully understood, but if these guidelines are followed, they might reduce the risk for Cyclospora contamination.

CDC monitors the occurrence of cyclosporiasis in the United States and helps state health departments identify and investigate cyclosporiasis outbreaks to prevent additional illnesses.
