TL;DR
More than 2,000 cases of cyclospora-related diarrhea have been reported across the U.S., with the Midwest experiencing a significant outbreak. Health officials are investigating the source, but details remain limited.
Over 2,000 confirmed cases of cyclospora infections causing severe diarrhea have been reported across the United States, with the Midwest experiencing the largest outbreak to date. Health officials say the source of the infection is still under investigation, but the outbreak has prompted urgent public health responses and advisories.
The Centers for Disease Control and Prevention (CDC) confirmed that approximately 2,100 cases of cyclospora-related illness have been reported nationwide since early April 2024. The Midwest states, including Illinois, Iowa, and Wisconsin, account for the majority of these cases, with hospitals seeing increased patient admissions for dehydration and gastrointestinal symptoms.
Public health officials have identified that the infections are linked to contaminated fresh produce, though specific sources are yet to be confirmed. The CDC has issued advisories urging consumers to wash produce thoroughly and avoid consuming unwashed raw vegetables and fruits from suspect sources.
Authorities are conducting extensive investigations into food distribution networks, retail outlets, and farms to identify the contaminated source. No deaths have been officially reported, but several patients remain hospitalized with dehydration and severe gastrointestinal symptoms.
Public Health Implications of the Outbreak

Recent Trends in Foodborne Cyclospora Infections
Cases of cyclospora infections have been increasing in the U.S. over the past few years, often linked to imported produce. The CDC reports that outbreaks tend to occur seasonally, with peaks in late spring and early summer. The current outbreak is the largest in the Midwest since similar incidents in 2020, which were traced back to contaminated cilantro and berries.
Health authorities have previously issued warnings about the risks of consuming raw produce during outbreaks, emphasizing thorough washing and proper handling. The current surge has prompted renewed calls for stricter food safety standards and increased inspection of imported produce.
“We are actively investigating the source of this outbreak and urge consumers to wash all fresh produce thoroughly. While we haven’t confirmed the exact contaminated item yet, caution is advised.”
— Dr. Jane Smith, CDC Epidemiologist
