Two new cases of E. coli bacteria infection among people who ate at a Lake Forest restaurant were confirmed Saturday and health officials said the restaurant would be closed until further notice.

The other latest case involves an employee who tested positive for E. coli despite not reporting any early symptoms.

Restaurant officials voluntarily closed the restaurant yesterday afternoon so all employees could be tested for E. coli infection, the health office announced in a statement today. The new cases prompted the HCA to suspend the restaurant's permit to operate.

All the stricken people, 10 children and two adults, reported eating at Foothill Ranch restaurant in Lake Forest in March. The new cases involved a teen who ate at the restaurant on March 25. Previously, health officials thought the outbreak applied only to people who had eaten at the restaurant on March 23 or March 24, the Orange County Health Care Agency announced in a statement today.
