I am in agreement here and it seems I have seen an actual regulation at some point in my life SOMEWHERE.
Chefs...stop and think about the plastic container that holds the paint/chocolate.
There are all sorts of regulations about plastic toys.
Huge scandal a few years back about toys manufactured by Fisher-Price in China (contained toxic substances not allowed by FDA).
Big recall...was sort of a wakeup call re what was being imported without really checking just because the importer was a trusted company with a big wallet.
Started the whole "Buy American" movement.
I actually went to the fda.gov site (showing the love here, Chefs!) and noticed the department that takes care of that sort of thing was not funded in 2013.
Looked around a bit and now have a huge headache and need to go lay down.

Will that one tiny portion of (product decorated with paint store gun) kill the guest who consumed it?
Most likely not.
IMO this is about ethics and responsibility.
You do whatcha gotta do to get by, right?
