Adverse reactions to shellfish are rare in young children and are usually not seen until the teenage years or adulthood. This may be a reflection of the fact that shellfish is not normally a part of the diet of young children.
Allergy to fish may begin in childhood and is likely to be life-long. The fish commonly known to cause allergic reactions include cod, flounder, hake, trout, haddock, halibut, herring, mackerel, pike, salmon, shark, snapper, sole and tuna. New Zealand fish include hapuka, kahawai, moki, parore, tarakahi, and warehou. Occasionally the allergy may not be to the fish itself but to a parasite.

This leaflet explains what fish and shellfish allergy is, the different symptoms, and what foods you will need to avoid.
