Michael Jackson's now-bankrupt former dermatologist Dr. Arnie Klein -- who fueled the singer with mass quantities of dangerous drugs -- has now been named in another sprawling drug controversy ... this time involving potentially dangerous Botox imported from foreign countries.
The FDA has issued a notification to more than 350 medical practices across the U.S. -- claiming they may have received unapproved meds, including Botox, from a foreign supplier -- and one of the docs on the giant list is none other than Arnie.
The suppliers in question are owned and operated by a company called Canada Drugs, though it's unclear where the drugs are manufactured.
According to the FDA, "These medications may be counterfeit, contaminated, improperly stored and transported, ineffective, and/or unsafe."
The notice continues, "Medical practices that purchase and administer illegal and unapproved medications from foreign sources are placing patients at risk."
But then again, Danger is Arnie's middle name ...
