Shellfish allergies are responsible for most emergency room department visits in food-allergic adults, and have generally been thought to be life-long.  But a new study, conducted by Rosalia Ayuso, MD, and colleagues at Mount Sinai, has found that sufferers may build up a tolerance to shrimp as they grow older. This is the first study to show that sensitization to shrimp allergens is greater in children than in adults, and that it may decrease with age. This study was sponsored by the Food Allergy Initiative, and more information about it can be found at the following link.
