At least five more people, two of them children, have contracted E. coli from an unknown source in Weber County.

No common food source has been linked to the bacteria, though officials say there seem to be no ties to an outbreak that occurred June 27-30. During that outbreak, at least five other people contracted infections, either directly or indirectly, from tainted lettuce served from a North Ogden Wendy’s restaurant.

Results of the current investigation, which involves analyzing stool samples from victims for recent food histories, should be available by the end of next week, reports the Standard-Examiner. If infections are found to be from a common source, the Weber-Morgan Health Department will release that information.
