These laboratory-confirmed cases of botulism demonstrate that clinical use of unlicensed botulinum toxin A can result in severe, life-threatening illness. Further education and regulation are needed to prevent the inappropriate marketing, sale, and clinical use of unlicensed botulinum toxin products.
