Lynn Terry of the Oregonian reports this afternoon that the Salmonella outbreak traced to a Mexican restaurant in Vancouver, Washington has continued to grow.

Clark County Public Health officials have confirmed 13 cases of salmonella poisoning and 33 probable cases.  Three people were hospitalized after eating at On the Border, located at 1505 S.E. 164th Ave. Two of them have been released.

Both patrons and employees were infected. Lab tests so far have confirmed that at least two people were infected with Salmonella virchow, which is rare in the Northwest. In fact, there have never been any cases in Clark County. But the strain has infected people in Europe, including in London in 2000 in which a food handler passed the bacteria to sandwiches that infected patients.
