"Some of the UK's best-selling chocolate bars, such as Mars and Twix, will no longer be suitable for vegetarians. [...] owner Masterfoods said it had started to use animal product rennet to make its chocolate products."

""If the customer is an extremely strict vegetarian, then we are sorry the products are no longer suitable, but a less strict vegetarian should enjoy our chocolate," said Paul Goalby, corporate affairs manager for Masterfoods." (BBC)

Ah yes, it's only extreme vegetarians who will be affected. All other vegetarians - i.e. those that eat animals - can continue to eat these products.

Good recovery Masterfoods.
