Abstract
Background:
The etiology of urticaria is often difficult to determine. However, in case of repeated circumstance-connected urticaria, the reason may be easily clarifyable.
Case:
A 51-year-old healthy woman repeatedly experienced occupational hand urticaria when handling fish food. An unexpected reason for the urticaria was found in that the fishfood contained histamine as a "contaminant".
Conclusions:
In fishfood batches, biological degradation can produce histamine and possibly other toxic substances that can lead to occupational health problems.
