Yes, I have read their web page concerning this because I did not want to eat chocolate that had milk in it as an ingredient and G&B list it as an ingredient. I'm not allergic to milk. I just thought it strange that dark chocolate would have milk as an ingredient and so I looked into it. They explain very clearly that they only list it as an ingredient because of the trace amounts that get into the chocolate from previous milk chocolate batches made on the same line.
It is hard for me to imagine that anyone could be that allergic to small traces of milk but then I haven’t any knowledge in this regard as milk allergies don’t concern me. It would seem to me that if you were that allergic to milk that you would find it hard to trust eating most things that you did not cook yourself in case someone failed to mention something they did not understand to be so important to such an individual.
Lactose-intolerant people can probably eat normal milk chocolate without any trouble.
People with an allergy to milk, particularly to casein proteins, and the peanut-allergy people are similar, can go into allergic shock when just tiny amounts of the protein set off their inflammation system. Once it's going, it snowballs on itself and they have to find a way to shut off the histamine or they can die.
I think listing milk as an ingredient is an interesting overreaction, but then they don't talk in their FAQ about any lawsuits they've already been party to. Or maybe their general liberalism (the whole organic-food ethic suggests they're pinko) extends to an overweaningly progressive philosophy towards food labelling. Soon they'll be wearing T-shirts indicating the pollutants each of them has picked up on their commute, and voting for democrats.
And yes, the truly allergic treat most restaurants like you or I would treat a taco shop that stores cleaning supplies in condiment bottles, and they shop and cook differn't, too.
