The Tennessee health department has confirmed that the seven people who fell ill ate at a Hixson restaurant between July 8th and 20th, reports WDEF-TV.

Since then, employees of the restaurant have all tested negative for the bacteria, and health inspectors have made sure that the restaurant was thoroughly sanitized.

Three of Janet King’s four children contracted the bacteria. The ordeal has devastated the family financially; Janet’s husband Mark, a Hamilton County deputy missed five weeks of work while doctors treated the kids in and out of the hospital.

Friends are hosting a daylong benefit at Veterna’s Park in Soddy-Daisy. Proceeds will help the Kings with extraordinary medical bills they now have. King says she’s more than grateful for the family, friends, who helped them during their time of need.
