Number of cyclosporiasis cases in the U.S. has surpassed previous records, CDC says

A MARTÍNEZ, HOST:

The nation's outbreak of cyclosporiasis has far surpassed previous records. The CDC counts more than 4,100 cases in the U.S. so far this year. And as NPR's Yuki Noguchi reports, health officials are working through a backlog.

YUKI NOGUCHI, BYLINE: The clusters of people sick with the diarrhea-causing parasite keep growing. The country's largest is in Michigan and Ohio, where health officials say thousands of cases began with iceberg lettuce from Taylor Farms in Mexico. So how many are actually sick right now? That's hard to pinpoint because of a lag in reporting. To confirm each case requires positive stool testing for cyclospora plus an interview with a state public health worker. Results are then reviewed before the CDC is notified. That process can take over a month.

It's slower these days, says Rutgers food safety expert Donald Schaffner. He says the Trump administration's deep cuts last year left public health generally with less money and fewer staff to handle surging caseloads.

DONALD SCHAFFNER: Realize, too, both at CDC and at FDA, these have been agencies that have been shaken up. And, you know, there's maybe fewer people there. There's less well-trained people there. And good people have been fired, and good people have left.

NOGUCHI: All this fuels consumers' uncertainty about when the outbreak might end.
