In brief: Depends

Crab allergy is a shellfish allergy and can develop at any time during adulthood.
Why some adults can consume crabs their entire life without any problems and others can go on to develop symptoms is unknown. Shellfish allergy is a common adult allergen and symptoms can vary from one accidental exposure to the next so avoidance once symptoms develop is the best way to manage.
