Fish allergy

In the process of doing a little research about fish allergies, I ran across this unpleasant little surprise: "Also, its potency as a food allergen was shown in a case report of severe anaphylaxis upon ingestion of sweets containing several grams of fish gelatin." and "Fish gelatin is commonly used in food and pharmaceutical products replacing mammalian gelatins."

Unfortunately, it looks like there hasn't been a lot of progress in trying to prevent/mitigate fish allergies.
