Massachusetts state officials say they found unclean conditions including visible black specks of fungus in steroids made by a pharmacy linked to a deadly outbreak of meningitis.

Gov. Deval Patrick said Tuesday the state has moved to revoke the license of the New England Compounding Center and three pharmacists.

State officials say a preliminary investigation found drugs were sent out before tests results on their sterility could be returned and a leaking boiler was located near a company clean room. They also said the company operated as a drug manufacturer by producing drugs for broader use, rather than filling out specific prescriptions for specific doctors, which is all its license allowed.
