Quick Summary

The FDA announced on Friday that it found cyclospora in a wastewater tank and drainage ditch at a Mexican farm linked to the largest US outbreak of the parasite, which infected nearly 13,000 people across 21 states, causing 570 hospitalizations and two deaths. Despite this finding, Mexico’s food safety authority previously reported no detection of cyclospora in lettuce or water from the same facility. Taylor Farms, which owns the farm but has not used the independent grower involved since November, is implementing new safety protocols following the outbreak.

Story summary

The Food and Drug Administration (FDA) announced on Friday that they have identified potential sources of cyclosporiasis linked to a large lettuce-related foodborne illness outbreak over the summer. The agency found cyclospora, a parasite causing severe diarrhea, in samples collected from Taylor Farms de Mexico facilities in Guanajuato, Mexico. Specifically, two positive samples were detected: one from an outgoing wastewater tank and another from a drainage ditch near iceberg lettuce cultivation areas.

The outbreak affected nearly 13,000 people across 21 states, resulting in 570 hospitalizations and two deaths. Despite the discovery of cyclospora at Taylor Farms de Mexico, the FDA remains uncertain about how exactly the parasite contaminated the lettuce. The agency has concluded its investigation into this outbreak.

Meanwhile, regulators from Mexico’s food safety authority previously stated that their own tests did not detect cyclospora in the lettuce or water samples taken at the facility, indicating ongoing uncertainty and controversy regarding the source of contamination.
