Parasite Scare: FDA False Positive Rocks Lettuce Recall
21 Jul
Summary
- FDA faced a false positive test result for parasite cyclospora.
- Taylor Farms lettuce is under investigation for a multistate outbreak.
- Cyclospora causes intestinal illness from contaminated food and water.
Federal health officials are focusing on lettuce from Taylor Farms as the source of a multistate outbreak of the parasite cyclospora. This investigation was briefly complicated by an inaccurate test result that the Food and Drug Administration (FDA) publicized before retracting it as a false positive.
Authorities have been tracking an increase in cyclospora cases, with initial investigations pointing to lettuce served at Taco Bell. Taylor Farms has recalled 25 products due to the potential contamination. The FDA's traceback investigation continues to identify shredded iceberg lettuce from Taylor Farms' operations in central Mexico as a likely source.
Cyclospora is a microscopic parasite that infects food, typically produce, when irrigated or washed with contaminated water. Ingesting it causes intestinal illness characterized by frequent bowel movements. As of the latest reports, over 1,645 people have been sickened and 141 hospitalized in the U.S. across five separate clusters of illnesses.
Despite challenges in directly linking recalled produce to illness due to testing limitations, investigators rely on consumption data and case patterns. Health officials emphasize the ongoing nature of new cases, underscoring the urgency to remove contaminated products from the market.
