The government is warning doctors and hospitals not to use any product from the specialty pharmacy that made the steroid suspected in a meningitis outbreak.
An official with the Food and Drug Administration said tests found contamination in a sealed vial of the steroid at the New England Compounding Center in Massachusetts. Tests are under way to determine if it is the same fungus blamed in the outbreak.
Federal officials on Thursday also updated the number of cases in the outbreak. Five people have died and 30 people in six states are ill. All received steroid shots for back pain.
The pharmacy issued a recall last week and has shut down operations. The steroid was sent to 75 facilities in 23 states.
