In reply to veteye:
Wasn't it back in the '90s when there was a health concern about using clingfilm on fatty foods (cheese, meats). Pretty sure as others have said they quickly brought out a safe alternative which can be used with any foodstuffs.
More importantly though cheese needs to breathe, wrapping in clingfilm makes it go sweaty and horrid (a quality rather than safety issue). Much better to use baking parchment or a beeswax wrap which will absorb excess moisture, then place into a tupperware box.
