I guess if it is there on the labelling then you would have no recourse to complain - so long as it is on the label somewhere then their job is done kwim? This applies to any food labelling - how often do you see in fine print on a package "may contain nuts" - heaps of times, but it is always in small print. It is up to us to read the labels carefully to make sure that there is nothing in it we don't like. I do agree though that in some instances the labelling should be clearer, particularly in products intentioned for children.
