The Daily Tarheel reports that health officials have not yet been able to pinpoint the source of contamination within the restaurant that led to at least 9 cases of confirmed E. coli O157:H7 among McAlister’s patrons.

Neil Newcomb, owner of the Franklin Street McAlister’s, said that he noticed a decline in business after last week’s revelations, but that customers are returning. "We need to be the perfectly run restaurant. If we were not, we are now," he said. "We anticipate bouncing back."
