Former factory farmer Craig Watts has tried Burger King's plant-based Impossible Whopper for the first time, in a recent video with NowThis.
Watts, who used to farm chickens for major food company Perdue, left the industry after exposing the conditions animals were kept in and now advocates for veganism.
'It's pretty close'
Tasting the meatless patty with President of Mercy for Animals, Leah Garcés, Watts said: "It really does, it tastes just like the whopper. It does. I'm surprised. I'm surprised it's that good.
"In a blind taste test I don't know, it's pretty close."
Impossible Foods itself considers its meat-free patty to be plant-based rather than vegan.
This is because, in 2017, it was revealed that a key ingredient - soy leghemoglobin aka 'heme' - from the brand's flagship item the Impossible Burger was fed to rats in order to test its safety. An excess of 180 rats were killed as a result of the testing.
CEO Pat Brown has reacted to the controversy, publishing a statement titled The Agonizing Dilemma of Animal Testing.
