Report

The recent ban on red dye No. 3 by the U.S. Food and Drug Administration (FDA) has sparked widespread concern among consumers, prompting them to re-evaluate their food choices. Many are not only checking for the presence of red dye No. 3 but are also scrutinizing other products for potentially harmful ingredients. In this context, red dye No. 40 has come under increasing scrutiny, as both dyes share similar colour properties but have different chemical compositions.

The Ban on Red Dye No. 3 and the Shift to Red Dye No. 40

Red dye No. 3, also known as erythrosine, has long been considered potentially harmful. California took action in 2023, prohibiting this food additive due to health concerns. In response, several food brands switched to using red dye No. 40 (or Allura Red). The FDA approved red dye No. 40 in 1971, and it has since become one of the most widely used food colourants. Although both red dyes originate from petroleum, red dye No. 40 is further mixed with aluminium to prevent leakage after being added to food products.

California’s Move to Ban Artificial Dyes in Schools

In 2024, California extended its ban on artificial dyes to include red dye No. 40 in schools, though the federal government still permits its use in food products. The federal government had already prohibited red dye No. 3 after studies linked it to cancer in rats and behavioural problems in certain children.

Concerns Over Red Dye No. 40’s Safety

While the FDA deems red dye No. 40 safe for consumption, its chemical similarities to the banned red dye No. 3 have raised concerns. Red dye No. 3’s association with cancer and behavioural issues in children has led experts to investigate whether red dye No. 40 could produce similar effects. Limited research exists suggesting that red dye No. 40 might be carcinogenic, and a few studies have linked it to behavioural changes in children. Additionally, red dye No. 40 may contribute to allergic reactions and migraines in some individuals.

Where You’ll Find Red Dye No. 40

Red dye No. 40 is a common ingredient in a wide range of food products, including Strawberry Pop-Tarts, Skittles, Swedish Fish, kids’ cereals, frosting, and juice beverages. With the FDA re-evaluating its safety standards for synthetic food colourings, the future regulation of red dye No. 40 remains uncertain.
