The UK has become the first European country to market 'lab-grown meat', with regulators approving chicken grown from animal cells for use in pet food. The 'Meatly' brand pet food has received authorization from the Animal and Plant Health Agency and the Department of the Environment, making it the first European company to sell cultured meat. The nutrients used to grow the cells are safe, and the final product is nutritious, bacteria- and virus-free. This makes the UK the third country to authorize the sale of cultured meat, following Singapore and the US.
