Typically the milk proteins, such as casein and whey, are the cause. This is different from lactose intolerance, which is caused by the milk sugar or lactose.
Is a milk allergy from only cows milk?
No, goat, sheep, and other milk can also cause a milk allergic reaction because there are similar milk proteins present in these milks as well.
With a milk allergy what products should be avoided?
The foods that are made from milk should be avoided. Those are: cheese, butter, yogurt, ice cream, and any food product that has milk or dairy in the ingredients.

There are personal products and cleaning products such as cosmetics and soaps that also have milk. These products should be avoided as well. Be sure to avoid all foods containing dairy, casein, and whey as well as their derivatives.
