Vegetarians will no longer be able to eat Mars bars.

Masterfoods, the owner of Snickers, Maltesers, Bounty, Minstrels and Milky Way has declared that it will start using animal byproduct to make its chocolate bars because of sourcing problems. One of the byproducts they may include, rennet, is a chemical squeezed from the stomach of dead baby cows. I'm not vegetarian, but you won't catch me eating one of those bars.
