Notes:
Seafood is a common cause of food allergy. Allergic reactions are reported by consumers following ingestion of seafood meat and by processing workers after occupational exposure to seafood by inhalation of vapors generated during cooking. Although seafood allergy is commonly observed in clinical practice, its precise prevalence is not established. Based on our estimates, approximately 100,000 to 250,000 Americans are at risk of developing allergic reactions to seafood products. In this study, skin testing, in vitro assays and double-blind, placebo-controlled food challenge were employed to investigate seafood allergy in shrimp-allergic individuals. As in most food allergy studies only 1/3 of the alleged shrimp-sensitive subjects had a positive shrimp challenge test. The combination of a positive shrimp skin test and shrimp RAST (〉11% bound) had the best predictive value (87%) for a positive challenge response. Although occupational seafood allergy is not well-studied, based on a Canadian investigation, it can be estimated that 57,000 American seafood workers are at risk of developing work-related allergic reactions. Since seafood is a major food allergen in consumers and industrial workers, further studies are necessary. Despite developments of new antiallergic therapies, avoidance continues to be the best “treatment”for allergic ingestive, inhalative and occupational disease.
