## Abstract

A diagnosis of food allergy can significantly affect the career prospects of military aspirants, as severe allergic reactions and the need to carry an adrenaline auto-injector are among the medical conditions that disqualify individuals from military service. Uncertainty regarding fitness for military recruitment may include candidates who were given a label of food allergy in early life with no recent reactions, those with mild oral symptoms when exposed to certain foods but recorded as allergic, others who have been prescribed adrenaline auto-injectors with an unclear indication, and those with childhood food allergies that may have resolved. Shellfish allergy is a prevalent and potentially fatal food allergy that typically persists throughout life. This case report describes a man in his early 20s with suspected prawn allergy, which became a concern during his job application to the Royal Navy. Despite positive skin prick tests and specific IgE levels indicating sensitization, the patient successfully passed an oral food challenge without reaction. This permitted the removal of the shellfish allergy diagnosis, allowing him to proceed with his military job application. This case highlights the importance of comprehensive allergy testing and food challenges in diagnosing food allergies, especially in cases with significant implications for career opportunities.
