KANSAS CITY, Mo. — Missouri health authorities reported another jump in cyclosporiasis cases Sunday, bringing the statewide total to 1,950, up from 1,577 the prior week. The jump comes as multi-state investigators continue to link illnesses to iceberg lettuce grown in central Mexico.
What is cyclospora and how it spreads
Cyclosporiasis is caused by Cyclospora cayetanensis, a microscopic parasite that infects the intestines and is spread when people ingest food or water contaminated with fecal matter containing the organism. The Centers for Disease Control and Prevention describes the illness as typically producing watery diarrhea and other gastrointestinal symptoms.
“with frequent and sometimes explosive bowel movements,”
The illness is less common than many bacterial foodborne infections such as Salmonella or E. coli, and many cyclospora cases are never definitively linked to a specific food item. Still, public-health officials have identified a connection between the current cluster of cases in 15 states and iceberg lettuce harvested in central Mexico and distributed to the U.S.
Where the outbreak stands in Missouri and nearby
Alongside Missouri’s statewide total, neighboring Kansas is reporting 748 cases and 32 hospitalizations. Health departments across affected states are monitoring case reports and working with federal partners to trace distribution chains and advise retailers and consumers.
| Jurisdiction | Reported cases | Hospitalizations (if reported) |
|---|---|---|
| Missouri | 1,950 | Not specified in state update |
| Kansas | 748 | 32 |
Symptoms, treatment and vulnerable groups
Common symptoms of cyclosporiasis include:
- Frequent, watery diarrhea
- Loss of appetite and weight loss
- Abdominal cramping and bloating
- Nausea
Symptoms may start days to weeks after exposure. While many otherwise healthy people recover with appropriate therapy, the infection can be prolonged or severe in some patients. Health officials typically treat cyclosporiasis with specific antibiotics; anyone who suspects they are ill should contact a health care provider for testing and treatment recommendations.
Guidance to reduce risk
State and federal health agencies advise several practical steps consumers can take to lower the risk of infection from produce:
- Thoroughly wash all fruits and vegetables under running water before eating, cutting or cooking.
- Scrub firm produce such as melons and cucumbers with a clean produce brush.
- Cut away any bruised or damaged areas before preparing produce.
- Refrigerate peeled, cut or cooked produce promptly.
- When possible, choosing locally grown produce or growing your own may reduce exposure risk.
Ongoing investigations and what to expect
Federal and state health officials are coordinating traceback investigations to identify distribution points for the implicated iceberg lettuce and to inform retailers and consumers if specific lots or brands are recalled or removed from shelves. The recall already announced by Taylor Farms covered iceberg lettuce grown in central Mexico after traceback work pointed to that supply.
Public-health teams will continue to monitor new case reports, work with laboratories to confirm infections, and seek to identify any additional contaminated products or distribution links. Because cyclospora cases can go unreported or be misattributed to other gastrointestinal illnesses, health departments emphasize testing when symptoms are consistent with the parasite.
What Missourians should know now
The rise to 1,950 cases in Missouri underscores the need for vigilance in food handling and in seeking care for persistent gastrointestinal symptoms. Avoiding raw iceberg lettuce from uncertain sources and following the produce-safety tips above are immediate steps consumers can take while investigators complete their work.
Health agencies will publish updates as new information becomes available and as traceback and laboratory results clarify the scope and source of the outbreak.
