Topic was a chocolate bar made by Mars, Incorporated in France and sold throughout Europe.
[1] In 1997, a Topic bar was found to have contained the remains of a mouse.
A subsequent court case ruled that Mars could not be found guilty of negligence under the Food Safety Act, due to the mouse originating from a supplier in Turkey, and the fact that Mars had been diligent in checking the Turkish operation.
[2] The chocolate bar was promoted in a series of radio advertisements broadcast in 2002 with the strapline "A joy to eat, but a bitch to make".
[3][4] These adverts featured actors Simon Pegg and Mark Heap who both appeared in the cult British TV comedy Spaced.
