— FDA says its investigation and outbreak data continue to point to Taylor Farms' iceberg lettuce

Federal health officials said Monday they remain focused on lettuce from Taylor Farms as the source of a multistate outbreak of the diarrhea-causing parasite Cyclospora, despite inaccurate test results that the government briefly publicized over the weekend.

FDA officials on Monday said a laboratory test incorrectly identified a positive result for Cyclospora on a sample of lettuce from Taylor Farms. The FDA posted the finding to its website on Saturday but then said Sunday that the result had been a false positive.
