Shellfish Allergy and some Ice Creams (http://allergy.hyperboards.com/action/view_topic/topic_id/6574)
On the FAAN site under shellfish allergies it states:
Should carrageenan be avoided by a shellfish-allergic individual?
Carrageenan is not fish. Carrageenan, or "Irish moss," is a red marine algae. This food product is used in a wide variety of foods, particularly dairy foods, as an emulsifier, stabilizer, and thickener. It appears safe for most individuals with food allergies. Carrageenan is not related to shellfish and does not need to be avoided by those with food allergies.

:thumbsup: Exactly.
If you don't avoid Nori (seaweed sheets used in Japanese cuisine) then there isn't any reason to fear carageenan, either.
(I personally like Nori a lot, but it can be an acquired taste.)
