Anaphylaxis Following Fish Ingestion in a Military Member.

We present the case of a 33-year-old active-duty male with a history of anaphylaxis following fish ingestion, allergic rhinoconjunctivitis, and multiple environmental and food allergies confirmed with serum-specific IgE testing. This report discusses the patient's clinical presentation, diagnostic evaluation, and management plan, including allergen avoidance, epinephrine use, environmental control strategies, and a case of unexpected severe anaphylaxis despite low serum-specific IgE levels. Military service requires stringent physical capabilities, and deployment requirements add an additional layer of complexity to the outlook of this case. These conditions underscore the importance of thoroughly analyzing allergic diseases in military personnel and leveraging clinical data to support informed decisions about their medical readiness. This includes implementing individualized care plans that emphasize strict allergen avoidance, ensuring consistent access to emergency medications, and applying environmental control strategies to reduce exposure risks. Additionally, healthcare providers should account for the unique challenges posed by austere deployment environments, such as limited food options and increased exposure to environmental allergens, when assessing fitness for duty. This particular service member was deemed deployable but ultimately, a comprehensive, data-driven approach is essential for balancing the health needs of service members with the operational demands of military deployment.
