Prewashed greens are extremely convenient, but whole heads of lettuce may be less risky during a cyclospora outbreak.

Salads – along with other fresh produce – are some of the healthiest foods you can eat. Leafy greens are rich in vitamins A, C and K, folate, potassium and magnesium. They also contain lots of fiber, which supports a healthy gut microbiome, promotes fullness, helps regulate blood sugar, and may contribute to healthy aging and better cognitive function.

But an ongoing 2026 outbreak of cyclosporiasis, caused by the cyclospora parasite, has sickened more than 11,500 people across the United States with explosive diarrhea and other gastrointestinal symptoms and has put a damper on salad consumption. A poll released on July 26 reports that 40% of U.S. adults have cut down on buying and eating fresh produce. News of egg and blueberry recalls, plus an investigation into a new, separate cyclospora outbreak, has not helped.
