The USDA has published an allergy resource, essentially an annotated bibliography on food allergy information. The introduction states:
This publication is a collection of resources on the topic of Food Allergies and Intolerances for consumers. Resources include books, pamphlets and audiovisuals and Web resources. Many of the pamphlets are available in single copies and some may also be purchased in bulk from the organization listed (Web addresses are provided for materials available online). The books and audiovisuals can be either borrowed from your local library or purchased from your local book store. Materials may also be available to borrow from the National Agricultural Library (NAL) collection. Lending and copy service information is provided at the end of this document. If you are not eligible for direct borrowing privileges, check with your local library on how to borrow through interlibrary loan. Materials cannot be purchased from NAL. Contact information is provided for the producing organization if you wish to purchase or order any materials on this list. This contact information can be found in section C.
