The Louisiana Department of Health and Hospitals confirms that a New Orleans-area child diagnosed with E. coli has died. The agency is now trying to find the exact source of the toxic infections that also made two other people sick.

Touro family physician Dr. Meredith Maxwell says, "If you look at a hamburger and it’s really pink, you could be at increased risk for E. coli, so you need to make sure your hamburger meat is cooked through and through.”
