One wouldn’t think that an animal rights group like People for the Ethical Treatment of Animals (PETA) would have a beef with a company that makes plant-based protein products, but that is what has happened. PETA, on its website, posted a blog titled “Why It’s Impossible for PETA to Get Behind the Impossible Burger.” That blog, as the headline implies, explains exactly why PETA is against Impossible Foods.While Impossible Foods, the maker of the Impossible Burger, proudly proclaims on its website “We found a way to make meat using plants, so that we never have to use animals again,” PETA found that at least one species of animals was used. The animals weren’t used as an ingredient for the food, but they were used to assure the product was safe for human consumption.In other words, laboratory rats were used to test the Impossible Burger.It’s a move PETA alleges was done in disregard of PETA’s advice and that there was “no need to hurt and kill animals to test its burger.”
