Health officials in London have put a deep freeze on supplies of breast milk ice cream after receiving health and safety complaints from two men.

Ice cream salon The Icecreamists in Covent Garden garnered headlines around the world last week after debuting their "Baby Gaga," a vanilla and lemon-scented dessert churned with human breast milk. The ice cream sold out within hours of its launch on February 25 and more batches were in the midst of being prepared.
