3. GOOD Meat
The Good Meat Company (“GOOD Meat”) has partnered with Huber’s to sell cultivated meat, making it the world’s first butchery to do so. With the introduction of the latest version of GOOD Meat’s cultivated chicken, the family-owned and operated business, Huber’s Butchery, is thrilled to add a new, locally produced offering to its display case and bistro menu.
“When we founded our butcher shop, we made it our mission to provide top quality and exceptional tasting meat products with the highest food safety standards at an affordable price. Partnering with GOOD Meat is in keeping with that vision and the realities of our ever-changing food system,” said Huber’s Butchery Managing Director Ryan Huber. “Cultivated meat could be one of the solutions to over-farming due to increased population size and density and an increase in animal protein consumption in many parts of the world,” added Executive Director Andre Huber.
4. Eat Just
Eat Just is so far the only company to have its cultivated, 3D printed meat product approved for public sale in Singapore, the only country to permit lab-grown meat to be sold. Its cultivated chicken product was green-lighted in 2020 and Eat Just has been working with Huber’s to offer chicken sandwiches and pasta dishes to the general public. This is with limited dining slots and once-a-week availability on the menu.
“Cultivated meat is real meat, but you don’t have to slaughter an animal,” says Josh Tetrick, chief executive of Eat Just, who spoke to the BBC from San Francisco. “This way of eating makes sense for the future,” he says.
