Ecoli Outbreak spreads

"Illnesses are still occurring, and we consider the outbreak to be ongoing," said Dr. Christopher Braden, an epidemiologist with the Centers for Disease Control and Prevention.

The CDC said it expected the number of cases to grow. As of Friday afternoon, the agency had counted 62 confirmed cases in six states, most of them in New Jersey, New York, Pennsylvania and Delaware.

South Carolina and Utah reported one case each. South Carolina health officials said Friday that their case involved a girl who had stopped at a Taco Bell in Pennsylvania last month while traveling. It was not immediately known if the Utah victim had recently been in the Northeast.

Forty-nine of those who got sick were hospitalized, and seven developed a type of kidney failure, the CDC said.

Laboratories continued testing food samples to find the source of the bacteria.

Some restaurants remained closed Friday, with huge garbage bins in parking lots as workers threw out food, cleaned kitchens and re-stocked supplies.
