I've been searching through the internet and can't really find anything about this specific topic. I have allergies to most animals; dogs, cats, horses, goats, pigs birds(feathers) and I also have a mild allergy to red meat. If I'm allergic to an animal is it bad for me to have dairy products that come from the animal? I don't have any bad side effects (that I'm aware of) if I eat cheese/dairy, I've never really drank milk so I can't say if that would have an effect on me. I have, however, developed cystic acne over the past few years and wonder if this could be the issue.
