CDC Cyclosporiasis Outbreak Expands to 15 States, Including 2026

The CDC cyclosporiasis outbreak has expanded to 15 states, including Arkansas and Missouri, raising concerns about food safety and public health. This parasitic infection, caused by Cyclospora cayetanensis, has already sickened thousands across the nation. Understanding the outbreak's scope, symptoms, and prevention is crucial for protecting yourself and your family.

What Is Cyclosporiasis and How Does It Spread?

Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis. It spreads through the fecal-oral route, typically by consuming contaminated food or water. The most common source in recent outbreaks has been recalled lettuce, but other fresh produce like cilantro and raspberries have also been linked in past incidents.

The parasite is not spread directly from person to person, but it can survive in contaminated environments for long periods. Once ingested, the parasite invades the small intestine, leading to a range of gastrointestinal symptoms that can be debilitating.

CDC Outbreak Expansion: Which States Are Affected?

The Centers for Disease Control and Prevention (CDC) has expanded its investigation to include 15 states, with new additions like Arkansas, Missouri, Iowa, Nebraska, New Hampshire, and North Carolina. As of July 28, the CDC reported 6,707 laboratory-confirmed cases and approximately 11,500 suspected cases awaiting confirmation. Cases have been reported in 45 states since May, but the hardest-hit areas are Michigan and Ohio.

Health departments in these states are working with the CDC to trace the contaminated food source. The FDA is also involved in the investigation, focusing on recalled lettuce products.

Symptoms of Cyclosporiasis: What to Watch For

Symptoms typically appear about a week after infection and can include:

• Watery diarrhea
• Appetite loss and weight loss
• Bloating and gas
• Extreme fatigue
• Low-grade fever
• Stomach cramps
• Nausea and vomiting

Without treatment, the illness can last from a few days to over a month. In some cases, symptoms may relapse. The CDC advises staying well hydrated and seeking medical attention if symptoms persist.

Treatment and Prevention: How to Stay Safe

Cyclosporiasis is treatable with antibiotics, typically trimethoprim-sulfamethoxazole. However, prevention is the best approach. Always wash fresh produce thoroughly, avoid consuming untreated water, and practice good hand hygiene.

The CDC recommends that anyone experiencing symptoms after consuming recalled products contact their healthcare provider. Early diagnosis can reduce the severity and duration of the illness.

Key Takeaways for Consumers
