Tag: Malachite green

While malachite green is an effective fungicide for fish, its metabolite, leucomalachite green, is the primary residue that accumulates in the fatty tissue of food-producing fish, raising significant health concerns. This chemical is not approved for use in food animals in many countries due to its potential toxicity. The presence of leucomalachite green in food is a matter of strict regulation and continuous monitoring.

According to the Environmental Working Group (EWG), studies have found that synthetic food dyes, including FD&C Green No. 3, can cause or exacerbate neurobehavioral problems such as hyperactivity in some children. This highlights a growing concern over the various forms of green dye present in modern life and their potential physiological impact.
