Public health authorities are investigating a growing outbreak of Cyclospora, a foodborne illness caused by the microscopic parasite Cyclospora cayetanensis.
Health experts are encouraging consumers to follow proper food safety practices to protect themselves and their families from infection.
According to reports, hundreds of confirmed cases have been identified, while many more are being reviewed. Although investigators are working to determine the exact source of the outbreak, the food responsible has not yet been identified. As a result, consumers are advised to remain cautious when purchasing and preparing fresh fruits and vegetables.
Cyclospora is a parasite that infects the intestinal tract and can cause uncomfortable digestive problems. Common symptoms include watery diarrhea, frequent bowel movements, stomach cramps, loss of appetite, fatigue, nausea, and weight loss. Symptoms may not appear immediately and can take up to two weeks after exposure to develop. If left untreated, the illness may continue for several weeks.
The parasite is often linked to fresh produce that becomes contaminated during growing, harvesting, or processing. Foods associated with previous outbreaks have included lettuce, cilantro, basil, green onions, raspberries, and other fruits and vegetables.
Warm and humid environmental conditions may help the parasite survive for longer periods.
Consumers can lower their risk of infection by taking a few simple precautions. All fruits and vegetables should be washed thoroughly under running water before eating, cutting, or cooking. Firm produce can be gently scrubbed, and outer leaves of lettuce or leafy greens should be removed and discarded before use.
Choosing whole produce instead of pre-cut or packaged salad mixes may provide an added level of safety during outbreak investigations. Cooking vegetables and herbs whenever possible can also reduce the risk because heat effectively destroys the parasite.
Good hygiene is equally important. Hands should be washed with soap and water before preparing food. Cutting boards, utensils, and kitchen surfaces must be cleaned regularly. Ready-to-eat foods should also be kept separate from raw produce to prevent cross-contamination.
People who experience diarrhea lasting more than a few days should seek medical advice. Since routine stool tests may not always detect Cyclospora, discussing possible exposure with a healthcare provider can help ensure proper testing and treatment.
By following food safety guidelines, consumers can better protect themselves while the investigation continues.
