I went to Germany with a son with severe food allergies to milk, eggs and tree nuts last summer. I just wanted to share a product brand that we found to be safe. The company Alpro makes soy milk, margarine, yogurt and pudding that are good tasting. It was generally available in the area we traveled to in northern Bavaria. From their website, they seem to distribute products throughout Europe. They have an email address on their packaging and responded to my questions of cross contamination quickly. Those products made are lives so much easier while we were there. I have posted a full travelogue of our allergy experiences on this trip here: http://tinyurl.com/bc477r7
I hope this is of help.
