More contamination has been confirmed in additional vials of drugs produced by the Massachusetts compounding pharmacy blamed for the ongoing outbreak of fungal infections that have sickened hundreds and led to 36 deaths. But federal health officials said there’s no evidence to date that the new drugs have sparked any additional outbreaks of fungal meningitis or other illnesses. New laboratory results show bacteria and fungi present in unopened vials of three drugs different from the injection epidural steroids produced by the New England Compounding Center of Framingham, Mass., and already implicated in 541 infections, federal health officials said in a health alert released late Monday.
