People with a fish allergy might be allergic to some types of fish but not others.
Can cod fish cause an allergic reaction?

In most cases, symptoms appear within 1 hour immediately after eating such as reddening of the face, particularly around the mouth and earlobes; hives; headache; vomiting; and diarrhea.
