I too am furious at Cadbury's insult to its customers by saying they never made gluten free statements. Here is a link I had in my favourites - http://www.cadbury.com.au/Products/Gluten-Information.aspx. Unfortunately I didn't print it and now the link doesn't work of course. If the was a potential for cross-contamination it should have previously been labelled. Australian coeliacs falsely chose their products over others because of their labels. Hopefully Food Standards Australia are onto this and they get fined, and we get a well deserved apology!
