During the past five summers, a large number of cyclosporiasis cases have occurred in Texas. Therefore, the Texas Department of State Health Services is advising healthcare providers to consider testing patients for the parasite Cyclospora if they have diarrheal illness lasting more than a few days or diarrhea accompanied by severe anorexia or fatigue.
Previous outbreaks of cyclosporiasis have been associated with consumption of imported fresh produce, including: fresh cilantro, pre-packaged salad mix, raspberries, basil, snow peas, and mesclun lettuce. Although washing may not eliminate all risk of transmission since Cyclospora can be difficult to completely remove from produce, thorough washing of all fresh produce is recommended. Cyclospora does not appear to be spread through direct person-to-person contact.
