I know this is weird, but some red dye comes from a bug! Here's some info:
Red dye allergy occurs when a child or adult is affected by red food coloring #2, which is also known as cochineal extract or carmine. This type of dye is processed using dried insects, particularly the cochineal bug found in the Canary Islands and South America. According to several studies, the red dye #2 is one of the most common food colorings that causes red dye allergy on children.
Another red dye is known as the FD&C red dye #40, which is used for three purposes - food, drugs and cosmetics, hence the name "FD&C". According to a survey performed by the National Academy of Sciences, the red dye #40 is the most widespread dye used by all ages.
The FD&C red dye is a member of the Azo family of colorants. Almost one million of these dyes are produced each year for various products starting from the first year it was discovered. Accounting to more than half of all the commercial dyes found in cosmetics, drugs and food, the red dye #40 produces different colors once processed.
Although the FD&C red dyes are one of the nine colors approved by the FDA, most of these dyes cause red dye allergy in hypersensitive people. Today, the Allura red from the Azo family is banned from Japan, Sweden, Austria and Norway.
However, the red coloring carmine is derived from the female Dactylopius coccus, a South and Central American insect.
