Cyclospora Season Is Over: Is Fresh Produce Safe?

The cyclospora season in the U.S. typically concludes in late summer, but health officials are monitoring a record number of infections from the foodborne parasite. In the most recent reporting period, the CDC reported 17,180 laboratory-confirmed cases, surpassing the total from the same period last year. Michigan experienced the highest number of cases, with confirmed infections ranging from 4,000 to 6,999. Unfortunately, two Michigan residents died after contracting the parasite.

The outbreak was traced back to processed iceberg lettuce imported from central Mexico by Taylor Farms de Mexico. Despite the CDC linking the outbreak to the company's produce, Taylor Farms claimed no product or environmental sample tested during the investigation was positive for the parasite. The CDC attributes a significant portion of the surge to this outbreak, but investigations into additional clusters with unconfirmed sources continue.

Following the recall of the implicated lettuce, cases have significantly decreased, with no specific risk factors identified for consumers at this time. However, health experts advise purchasing whole heads of lettuce instead of pre-cut greens to minimize contamination risks. While no widespread recalls involving other produce categories have emerged from the lettuce investigation, federal regulators and food safety experts stress that the recalled items are unlikely to remain on store shelves.

Consumers are reassured by the CDC's statement that there is no known or documented reason to avoid lettuce at this time. Nevertheless, the summer outbreak has heightened public concern over fresh produce, prompting some shoppers to switch to locally grown products or reduce salad green consumption. As cyclospora typically disappears after August due to environmental and agricultural factors, experts advise continued food safety practices rather than avoiding fresh produce altogether.
