Squid, allergenic food

Castillo et al. (1996) studied 142 food-sensitized patients from Gran Cranaria, Spain. Of these individuals, 120 reported clinical symptoms following ingestion of one or more foods. While shrimp was the most common allergenic food, squid was the second most common allergenic food with 33 cases. Additionally, 12 cases were reported to oyster, 10 to clam, and 10 to mussels.
