There are over 30 confirmed cyclosporiasis cases reported so far this summer in the Houston area.
The intestinal illness is caused by a microscopic parasite that's typically spread through contaminated produce or water and can cause explosive diarrhea and stomach cramps.
The big picture: Cyclosporiasis cases tend to increase during the summer months, Theresa Tran, Houston Health Department director, says in a statement.
While the CDC is investigating a multistate increase in cases, Tran says local officials haven't seen an unusual increase in the Houston area compared with recent years.
By the numbers: As of Wednesday, the Houston Health Department had confirmed 16 cases in the city and Harris County Public Health had confirmed an additional 18 cases.
For context, Houston reported 66 in 2025, 25 in 2024, and 156 in 2023, ABC 13 reports.
What they're saying: "We have not found a common source for our cases or any linkages between our local cases and other cases around the country," Tran says, adding that "the myriad benefits of eating fresh produce far outweigh the potential risk of contracting cyclosporiasis."
💧 Tran's pro tip: Wash fresh produce thoroughly under running tap water and wash your hands with soap and water before eating to reduce the risk of infection, Tran says.
