The Texas Department of State Health Services (DSHS) says the source of the outbreak has not been identified yet; however, because past outbreaks have been traced to fresh imported produce. DSHS encourages people to wash produce thoroughly, though that may not entirely eliminate the risk because Cyclospora can be difficult to wash off.

Cyclosporiasis is an intestinal illness caused by consuming food or water contaminated with the Cyclospora parasite. The major symptom is watery diarrhea lasting a few days to a few months. Additional symptoms may include loss of appetite, fatigue, weight loss, abdominal cramps, bloating, increased gas, nausea, vomiting and a low fever. Symptoms may come and go multiple times over a period of weeks.

Last year, Texas had 351 cases, more than any other state. In most previous years, the number of cases reported was in the single or low double digits. For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page
