Several media outlets are reporting that 20-month-old Jaycee Burgin, of Newport, Tenn., died just before 11:00 p.m. Tuesday at the University of Tennessee Medical Center due to an E. coli infection. She was diagnosed with the infection on October 9.

Officials with the East Tennessee Regional Health Department said Wednesday the source of Jaycee’s infection has not been confirmed.

Her family says Jaycee had a little bit of hamburger meat the Saturday before she got sick but they don’t know if that was the cause of her infection.

Since no other E. coli infections have been reported recently in Cocke County, health officials say they think the cases will be limited to Burgin’s.

Officials also say Burgin’s case was not related to three cases of children’s E. coli infections being treated in Knoxville, which have been linked to recalled meat produced by Minneapolis-based Cargill.

Deaths are a sobering reminder that food safety is not simple. Our condolences to the family.
