Sensibilities to compounds known as allergens that come into contact with the skin, nose, eyes, and respiratory system cause allergic reactions.
An allergic reaction can take one of four different forms when your body is overly sensitive to a stimulus: anaphylactic, cytotoxic, immunocomplex, or cell-mediated. Each one can manifest differently in each person and is triggered in various ways.
Cross-contact happens when an allergy unintentionally spreads from a food that contains the allergen to a food that does not. The likelihood that a person with a food allergy would experience a reaction to the food is neither decreased or eliminated by cooking.
