Error of fact.

The statement "It is permitted by Food and Drug Administration (FDA) since 1956 only for use on skin on some Florida oranges." is in error in that Citrus Red No. 2 is not limited by the FDA to oranges in Florida. It may be used in any State or Territory subject to the restrictions of that entity.

California and Arizona are the only States that prohibit its use. Florida sets specific standards for its use on oranges, tangelos and tangors.

Citrus Red No2, is listed a possible carcinogen by the IARC (International Agency for Research on Cancer - World Health Organization) in category 2B which indicates that there is insufficient evidence of carcinogenicity in test animals or humans. Neither OSHA (US Occupational Safety and Health Administration) nor NTP (National Toxicology Program) list it as a known carcinogen (IARC 1975, University of Memphis 2004.). In summaries of tests on laboratory mice, a monograph on Citrus Red No. 2 (NLM) reports that of 40 mice, males and females, feeding 500 and 2500 mg/Kg daily for 2 years (NLM 2003) resulted in I papillary carcinoma of the bladder at the higher feeding level. In terms of a 50 Kg human (110 lbs.), these levels would be equal to consuming 25 or 125 grams of pure dye, daily, for an adult’s lifetime. Assuming oranges had the maximum of 2 ppm dye on the peel this would require the consumption of the peel of 12.5 million Kilograms (27.5 million pounds) of oranges (or 62.5 Kilograms (138 million pounds) for the higher level.) daily.
