US reports outbreak of foodborne parasite infection

An outbreak of cyclosporiasis, a foodborne parasitic infection causing "explosive diarrhea," is affecting numerous states across the United States, according to health officials. Michigan, in the north, is a primary focus with 1,562 reported cases as of Friday. The US Centers for Disease Control and Prevention (CDC) stated that 31 states had recorded cases by Thursday, resulting in dozens of hospitalizations but no fatalities.

Health authorities have yet to pinpoint the exact source of the contamination, which is typically linked to fresh produce. The detection process is complicated by a relatively long incubation period for symptoms to appear. Past outbreaks have been associated with foods such as bagged salads, cilantro, raspberries, peas, and chives.

Without treatment, the illness can persist for over a month. While rarely life-threatening, it can lead to dehydration. Officials advise thoroughly washing fresh produce or cooking it, as temperatures above 70 degrees Celsius can eliminate the parasite. Tracking the outbreak is also hindered by varying reporting systems among states, with some reporting confirmed and probable cases together and others delaying communication until investigations are closed.
