Citrus Red 2 is an artificial food dye used to color the skin of non-organic Florida oranges.
Citrus Red 2 is classified by the International Association for Research on Cancer as possibly carcinogenic to humans. In mice, increased mortality and liver damage was seen within weeks with a diet containing 0.1% Citrus Red. In mice injected with the dye, tumors appeared more often and were more severe compared to controls.
The dye is typically used only early in the citrus season when Florida weather does not allow for a bright enough orange colour to develop naturally.
