(Not entirely sure where to post this; many apols if it's in the wrong place.)
I just heard this morning that Fabricake Sugarcraft Ltd in the UK is recalling Rolkem Super Gold and Special Rose Gold. This only affects these two products, and they are refunding these two product lines if you bought from them (you'll need to return). It affects all sizes, batches and best before-dates. I will post the info and the link to the Food Standards Agency.

Fabricake Sugarcraft Limited is recalling Rolkem Special Rose Gold and Rolkem Super Gold which are food colours used to decorate food items (such as cakes) due to high concentration of copper.
