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