The Mountain Mail reports that local and state medical officials Tuesday confirmed six children in Chaffee County have been infected with Escherichia coli in the incident that began earlier in July.
With the incubation period for the bacteria nearing its end, Chaffee County Public Health Nurse Susan Ellis said Tuesday no new cases have been reported since about July 14.
She said 30 people will have been tested by Friday as investigators continue to seek the source of contamination.
Ellis said DNA from stool samples is being examined at the state laboratory in Denver. DNA samples from two of the children, she said, were identified as matching.
