Are there any regulations about airbrush guns used for cake decorating in the UK? I know that you have to use food colors, but can you use any airbrush gun, or does it to have been made specifically with food contact in mind?

Here in Denmark anything that comes into contact with anything meant for eating, has to have been approved by our version of the FDA, but I was wondering how rules are elsewhere, particularly the UK, where many Danes buy their airbrush kits (DinkyDoodle and Cassie Brown are popular). However if the UK doesn't have the same restrictions, technically an airbrush gun bought in the UK isn't legal to use for cakes in Denamrk :-/
