SOUNDBITE: JAN HARDING, DRANK TAINTED TEA, SAYING:               \"Immediately my whole mouth was on fire.\"               The Utah woman was critically burned in her mouth and esophagus after taking a sip of sweet tea laced with a toxic cleaning solution at Dickey's BBQ.               SOUNDBITE: JAN HARDING, DRANK TAINTED TEA, SAYING:               \"It was like a fire beyond anything you can imagine. I mean, it was not like drinking hot coffee.\"               Authorities say an employee mistakenly mixed the industrial cleaning solution containing lye into the tea thinking it was sugar.               The Hardings hope the incident will bring changes in the restaurant industry to avoid such dangerous mixups.               SOUNDBITE: JIM HARDING, HUSBAND, SAYING:               \"Bottom line, so no one ever has to go through this again.\"               The district attorney's office is expected to decide in the coming week whether criminal charges will be filed.",
