CDC Monitors Cyclospora Outbreaks in Nebraska and Iowa Amid Summer Surge
The CDC is tracking more than 840 cyclosporiasis cases across 31 states, with Nebraska and Iowa each reporting up to ten infections as the seasonal outbreak peaks.
The Centers for Disease Control and Prevention said it is monitoring cyclosporiasis, a parasitic intestinal illness, in 31 U.S. states, including Nebraska and Iowa. The CDC’s data show that more than 840 cases have been reported nationwide since May 1, while state health officials have confirmed between one and ten cases in each of the two Midwestern states.
Cyclosporiasis is caused by the parasite Cyclospora, which is typically transmitted through consumption of unwashed fresh produce. Common symptoms include watery diarrhea, fatigue, nausea and vomiting, with less frequent reports of fever, body aches and headache. Most infections resolve within days, but severe or persistent cases may require antibiotic treatment.
The illness is seasonal, with incidence rising in spring and summer; the CDC defines the cyclosporiasis season as May 1 through August 31. Past FDA investigations have linked outbreaks to fresh herbs and leafy vegetables, such as parsley, cilantro, snow peas, mesclun lettuce, spinach, salad mixes, and berries.
"Cyclospora infections are seasonal, with cases rising in spring and summer," a CDC spokesperson said.
Health officials in Nebraska, represented by CHI Health, have confirmed the presence of cases in the state. The agency continues to advise consumers to wash produce thoroughly to reduce the risk of infection.
