Cadbury's says it's in their milk chocolate made in China.

Well, I'm not embarassed to say it: I've always thought Cadbury's chocolate was swill. :D

I like some of the stuff they make in NZ, especially the Crunchie bar, but that wouldn't be affected since they use locally-sourced milk.

I would be suspect of anything that came from China that had milk in it. Luckily it's not likely I will be buying anything like that. I am upset at the company and Chinese government who left this to go so long when they knew there was a problem.
