Safety in brief

Better avoided

Recorded EatMatrix rating, not a new clinical review. The amount, your sensitivities and country rules still matter.

Watch for
Recorded sensitivities: azo dye sensitivity.
Our advice
Read the whole food label and consider how often you eat the product. A name or E number does not tell you the amount, and an ingredient rating cannot assess the entire food.
What it is

Red 2G is a synthetic monoazo dye once used as a red colourant, mainly in meat products. EFSA concluded in 2007 that it raises safety concerns because it is metabolised in the body to aniline, a substance suspected of genotoxic and carcinogenic potential. As a result, the EU suspended its use, and it is not permitted in foods in the US, Canada, Japan, or Australia/New Zealand.

Also appears on labels as: Red 2G, Red2G, Red-2G, E128, E 128, E-128, Food Red 2G, Red Colour 2G, Synthetic Red 2G, Red Dye 2G.
