On that I have been lucky. I have not had problems with cross contamination with milk in manufactured foods. I generally eat things "made on shared equipment on in a facility with milk" with no problem and I only avoid things that seem a little suspect in manufacturing processes or which have a lot of ingredients. I have had one issue with Dirty chips and dairy but I could actually taste that it was contaminated with milk powder, so I think that was a special batch problem (I don't eat them any more). Before I had this almond thing pop up, I'd gone 18 months with no reactions to my other allergens. Beyond my previous restaurant and catering reactions and one reaction when someone stayed at my house and had butter in the fridge and must have double dipped something, they have not been so problematic. I've been lucky in that regard.
