U.S. health officials have traced a food poisoning outbreak from romaine lettuce to at least one farm in California. The FDA told consumers to avoid romaine lettuce just before Thanksgiving. The government also narrowed the source of the outbreak to three California counties: Santa Barbara, Monterey and San Benito. That's down from six California counties under investigation when regulators began warning the public last month. Lettuce from outside the three California counties that was harvested after Nov. 23 should be safe to eat.
