The U.S. Centers for Disease Control and Prevention (CDC) reports a rapid spread of the food-borne parasite cyclosporiasis across the United States.
This outbreak represents a significant public health concern due to the scale of the infection and the severity of the gastrointestinal symptoms affecting thousands of people nationwide.
According to CDC data, cases have been reported in 31 states [1]. While some reports indicate at least 17 states have confirmed outbreaks [2], the broader reporting suggests the parasite is present in more than 30 states [3].
The impact on public health has been substantial. Nearly 3,000 people have been sickened by the parasite [4], and 86 people have been hospitalized [5]. However, the number of confirmed domestic cases officially reported to the CDC stands at 843 [6]. This discrepancy often occurs in food-borne outbreaks because many sickened individuals do not seek medical care or are not tested.
Cyclosporiasis causes severe gastrointestinal illness, often characterized by explosive diarrhea. Investigators said contaminated produce is the suspected source of the outbreak, though the exact cause remains unclear. The CDC is actively investigating to identify the specific food product responsible for the spread.
Public health officials said caution is advised with fresh produce while the investigation continues. The parasite is typically ingested through contaminated food or water, and the current multi-state pattern suggests a widespread distribution point in the food supply chain.
“Nearly 3,000 people have been sickened by the parasite”
The gap between the nearly 3,000 estimated illnesses and the 843 confirmed cases highlights the difficulty of tracking food-borne parasites, as many infections go unreported. Because the outbreak spans 31 states, the source is likely a commercially distributed produce item, meaning a large-scale recall may be necessary once the CDC identifies the specific contaminant.
