Cadbury launches investigation after 'wasp is discovered' in bar of Dairy Milk

A wasp found in bar of Cadbury chocolate

Cadbury has vowed to launch an investigation after a picture of a wasp embedded into one of its chocolate bars was posted on Twitter.

Jake Keating, from Liverpool, tweeted the image after he found the insect lodged inside a bar of Dairy Milk.

He used Twitter to contact Cadbury via their official account (@CadburyUK), saying: "As if I have just found a WASP in my chocolate!!! What are you gonna do about this!?!"

The company swiftly responded on the social networking website, replying:"We'd love to reply with a pun, but we want you to know how seriously we're taking this, so we won't,"

The image soon swept around Twitter, prompting Cadbury to take action, assuring their other followers the matter was being dealt with: "‘Hi guys, we’re investigating this and are in contact with the original poster. Thanks for flagging."

Cadbury, based in Birmingham, is listed as the second largest confectionery company in the world, after being acquired by Mondelez International in 2012.
