Botox shots, possibly counterfeit, linked to botulism-like illnesses

Federal officials are trying to determine the source of Botox injections — some of the shots potentially counterfeits — linked to an outbreak of botulism-like illnesses in several U.S. states.

The Food and Drug Administration told CBS MoneyWatch it is working with other federal and state agencies to identify the cause of an outbreak that has sickened at least six people in Illinois and Tennessee injected with the botulinum toxin. 

The Tennessee Department of Health reported four people in the state had been stricken with botulism-like symptoms, including two hospitalized after getting possible counterfeit injections.
