A new lawsuit filed by the Center for Food Safety (CFS) claims that a color additive used to make Impossible meat look more like real beef could be harmful to human health.
The additive, soy leghemoglobin, creates the "bleeding" effect in the plant-based meat alternative but is made of genetically engineered yeast. While the substance was deemed safe for consumption by the Food and Drug Administration (FDA) in 2019, the lawsuit is challenging this decision, saying that soy leghemoglobin wasn't subjected to rigorous-enough safety tests.

According to the lawsuit, there must be "convincing evidence" of safety for any color additives to get approved by the FDA, but no such regulation is in place for food additives. It's not clear which category the novel additive falls under. Soy leghemoglobin also has "no history or knowledge of human dietary exposure." Based on this, the CFS says the FDA's approval of soy leghemoglobin should be vacated.
Impossible Foods reportedly submitted an animal study about its products that the lawsuit says "did not meet the minimum standards for such studies" and that "should have triggered additional, long-term testing" which didn't occur.
Studies have shown that certain color additives, also sometimes called food dyes, have harmful effects to animals and humans. Ones like Red 3, Red 40, Yellow 5, and Yellow 6 have been linked to cancer. However, results of a 2018 study raised no issues regarding carcinogenic properties of leghemoglobin protein (LegH) from soy, as it looked at the effect of the additive in humans.
