Can one develop an allergy to a shellfish by eating a meal of it for 5 days in a row?

1 doctor agrees

In brief: Yes

The latest opinion (& yet a very old opinion) is that protracted avoidance of a food more likely results in allergy than early exposure.
Intermittent rather than routine exposure is also more likely to result in a food allergy. So the question is less 5 straight days of shellfish and more when was the last time shellfish was eaten.

In brief: Typically not

This is not common for any food allergy.
Eat the food, have a reaction; eliminate the food and reaction goes away. Eat the food again and the reaction happens again. If you really want to know, see an allergist for testing and discussion.
