Skin Triggering Food Allergy

5/6/2018:  Research shows that touching infants with residue of peanut, egg, dairy or other allergens can trigger a food allergy as the allergen can pentrate the skin, especially if the skin is very clean or has a soap residue.  It is advised not to 'over clean' the infant as the natural oils on the baby's skin can help to protect the baby from triggering allergens via the skin.  It also is best to wash hands and lips after handling or eating allergy-common foods before touching or kissing the baby.
