The U.S. Centers for Disease Control and Prevention (CDC) released its latest weekly update on Thursday, confirming a total of 15,716 cases of cyclosporiasis across 47 states. The figure represents an increase of 1,821 cases from the previous week’s report.
According to the CDC, the confirmed cases have resulted in 828 hospitalizations and two deaths as of August 17. In addition to the confirmed cases, the agency noted that at least 11,841 additional reports are pending further investigation and analysis.
Outbreak sources and ongoing investigations
The agency highlighted that the numbers include cases tied to a multistate outbreak linked to recalled iceberg lettuce. CDC officials said they are actively investigating that cluster while also tracking several other emerging clusters whose sources have not yet been identified.
Specifically, the CDC and the Food and Drug Administration (FDA) are examining at least six additional clusters of cyclosporiasis. The investigations aim to pinpoint the contaminated food items or other vectors responsible for spreading the Cyclospora parasite.
State impact – Michigan’s experience
Michigan, which was the hardest‑hit state during a prior 17‑state outbreak, reported 13,909 cases linked to the parasite last week. That figure reflects roughly an 11 % increase from the prior week, though state health officials indicated the rise largely reflects a processing backlog rather than a sudden surge in new infections. They added that the worst of the outbreak may be behind it.
Public health implications
Cyclosporiasis is a food‑borne illness caused by the Cyclospora parasite. Symptoms typically include watery diarrhea, nausea, abdominal cramping, and other gastrointestinal discomfort. While most healthy adults recover without severe complications, the illness can be more serious for the elderly, young children, and individuals with weakened immune systems.
The current outbreak ranks among the largest food‑borne illness events in recent U.S. history. Public health officials have warned consumers to exercise caution when handling fresh produce, especially leafy greens and raw vegetables, and to consider cooking or thoroughly washing items before consumption.
Consumer response and guidance
Since the outbreak was first identified, many Americans have reported avoiding fresh produce or limiting restaurant dining while the investigations continue. The CDC advises anyone experiencing prolonged gastrointestinal symptoms to seek medical attention and to inform their healthcare provider about possible exposure to contaminated food.
Both the CDC and FDA continue to monitor the situation closely, issuing updates as new information becomes available. Consumers are encouraged to stay informed through official public‑health channels and to follow any recall notices or safety advisories that may be issued.
