                                According to the UK Food Standards Agency, precautionary allergen labels like 'may contain milk' are intended for health and safety, not as an ingredient statement. So, is a product with a 'may contain milk' warning vegan? Yes, if no animal-derived ingredients are listed, it can still be considered vegan, but the reason why is rooted in the difference between trace amounts and intentional ingredients.
