Health officials have not identified the sources of a cyclosporiasis outbreak that has infected over 3,000 people across 31 US states.
- Michigan is the hardest-hit state, with more than 2,600 cases, followed by New York.
- Steven Manderach of the Association of Food and Drug Officials said the parasite is notoriously difficult to trace, requiring large quantities of food for testing.
- Jodie Guest of Emory University said the one-to-two-week incubation period complicates linking cases to specific food sources.
- Hope Shuler of the Colorado public health department said the state has received less federal funding and fewer staff to monitor cases.
