Milk

Milk is one of the most common food allergens, particularly among infants and young children. A milk allergy is an immune response to proteins found in milk and milk products. The proteins most commonly associated with milk allergy are casein and whey, found in both cow's milk and, to a lesser extent, in goat's milk, sheep's milk, and other mammalian milks.

Milk proteins can be found in various food products and ingredients, including milk (obviously), cheese, butter, yoghurt, ice cream, baked goods, processed foods, and many more. It's crucial to carefully read food labels, as milk or milk-derived ingredients may be listed under various names, such as whey, casein, lactose, curds, and ghee.
