The search continues this morning for the source of an E. coli outbreak across the St. Louis area. So far 28 people have been sickened by the bacteria. Health officials say several of them had visited Schnucks salad bars before becoming sick. But so far, all of the samples taken from the grocery stores tested negative for E. coli.
Schnucks officials say they removed several items from their salad bars puerly as a precaution.
