Cyclospora Outbreak Affects Nearly 7,000 People Across 34 States

As of July 15, 2026, a cyclospora outbreak has resulted in nearly 7,000 reported cases across 34 states. Michigan health officials identified lettuce and salad greens as a potential source, advising consumers to buy whole heads, discard outer leaves, and wash the remaining parts. However, no specific grower or supplier has been identified, and the Centers for Disease Control and Prevention (CDC) has not confirmed whether this is one outbreak or multiple clusters. The difficulty in tracing cyclospora is compounded by reduced public health resources, including cuts to food safety staff and changes in surveillance protocols. The Food Traceability Rule, which could aid in tracking contaminated food, has been delayed until 2028. Michigan has reported 3,309 cases so far this year, significantly higher than the usual 50 cases annually, but the state cannot connect its findings with those in other states or trace shipments back to farms. The uncertainty surrounding the outbreak has led to misinformation and public concern, with some fast-food chains mistakenly announcing product shortages related to the outbreak.
