Allergy to hen's egg occurs in 2% of all small children. By the age of 4, most children have grown over their chicken egg allergy. Less than 1% of all adults maintain a chicken egg allergy.
Someone who tolerates cooked, however, may react to raw egg. There are also more (severe) reactions to egg whites than to egg yolks.Examples of ingredients and products that (may) contain egg:

An allergy to hen's egg protein can manifest as eczema (constitutional eczema). However, it can also cause an anaphylactic reaction. In this case, a severe allergic reaction occurs within a short time after eating a foodstuff containing hen's egg. This can lead to swelling of the skin, hives, shortness of breath and ultimately even allergic shock. Fortunately, this is very rare.Why one child reacts with eczema and another with such a severe anaphylactic reaction is not known. Some children may also react with localized swelling of the skin when it comes in contact with a food containing chicken egg, or with spitting and abdominal pain after eating an egg or soy food.As a parent, you may recognize a chicken egg allergy by the child reacting after eating chicken egg. However, this is not always obvious in practice, as many foods contain small amounts of chicken egg.
