Texas+Flag+mapCDC’s Aug. 11 update states that clusters of illness linked to restaurants or events have been identified in Texas (157 cases, according to CDC; 237 cases, according to the Texas Department of State Health Services), Wisconsin (10), and Georgia (22). CDC added that cluster investigations are ongoing in Texas and Georgia.

A recent surge in reports of illnesses due to the parasite Cyclospora has prompted DSHS to investigate the infections in hopes of determining a common source. DSHS has received reports of 237 Cyclosporiasis cases from around Texas this year. Past outbreaks have been associated with cilantro from the Puebla area of Mexico. While the investigation into the current outbreak is ongoing, DSHS has identified imported cilantro as a possible source of some infections.

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. People who think they may have a Cyclospora infection should contact their health care provider.

DSHS recommends thoroughly washing fresh produce, but that may not entirely eliminate the risk because Cyclospora can be difficult to wash off. Cooking will kill the parasite.
