diarrhea parasite. Okay, why is Taylor Farms saying that the FDA issued it an apology over the cyclospora outbreak? And does that mean we don't actually know what's cost thousands of people across the Midwest to get so sick? No, here's what's actually going on. The outbreak has still been traced back to iceberg lettuce supplied by Taylor Farms, with many people, although not all, saying that they ate at Taco Bell locations across five states. Now, these illnesses started in mid-May, so food experts tell us it's likely that the food that made them sick is long gone at this point. The FDA, as part of its outbreak investigation, started testing samples as part of what it calls targeted import surveillance. And on Saturday, it said that a sample of Taylor Farms' shredded iceberg lettuce had tested positive for cyclospora. Now, this was lettuce that was not included in the ongoing recall. The next day, the FDA said, actually, no, that should be considered a false positive. But the ongoing recall still stands. The FDA on Monday cited, quote, overwhelming epidemiological data. So Taco Bell, Jack in the Box, and several other food suppliers said they've removed recalled lettuce. Walmart also said it removed some products as a precaution, with sell-by dates out to August 3rd. So how worried do you need to be right now? Well, Rutgers food safety expert Dr. Donald Schaffner tells us that the food that started making people sick likely is not out there anymore. But we may still see case counts rise as people who are already sick are added. Let me tell you something.
