Where does peanut allergy come from?

I had a conversation yesterday with a pediatrician who told me about a 10 month old patient, who had a reaction the very first time he ate peanut. Typically, the immune system will produce allergic antibodies only after having been exposed previously. I responded that this child may have been exposed through microscopic breaks in his skin, as traces of peanut that are found in household dust can sensitize the immune system, leading to allergic antibody formation. It is important, therefore that any infant with moderate to severe eczema be screened for peanut allergy before consuming for the first time. Call us today to schedule an appointment to discuss this matter further.
