Tap title to read story
New York City. Health officials reported a sharp increase in cyclosporiasis cases this week, saying 381 cases have been recorded so far in 2026 in the city and 129 cases across New York State by early July; state and federal investigators have documented outbreaks in multiple states and are tracing fresh produce as the suspected vehicle.
As of July 9, the CDC reported 843 cases across 31 states while state-level totals suggest national counts exceed 1,000; Wisconsin reported 43 cases and Kentucky reported 100 cases since May. Michigan investigators interviewed more than 1,000 patients and identified lettuce and other salad greens as the strongest lead, though no single product or farm has been confirmed.
