U.S. health officials have lifted a public health alert, that advises people not to eat any romaine lettuce because of an E. coli outbreak. Jennifer McEntire of the United Fresh Produce Association says the Food and Drug Administration informed the group that a narrower alert would be announced. She says special labeling would be required for the romaine given clearance to go on the market. Health officials warned people last week not to eat any romaine because they hadn’t yet identified a source of contamination.
