5. Summary of Data Reported and Evaluation

5.1 Animal carcinogenicity data

One type of carrageenan was tested in rats by subcutaneous injection and produced local sarcomas. In mice and rats administered food-grade native carrageenan orally, the incidence of tumours was not greater than that in controls; however, this negative experiment is inadequate in terms of the number of animals used.

5.2 Human carcinogenicity data

No case reports or epidemiological studies were available to the Working Group.

Subsequent evaluations: Vol. 31 (1983); Suppl. 7 (1987) (p. 59: Group 3)
