Horsemeat has been found in beefburgers on sale in UK and Irish Republic supermarkets. But why do the British have such a revulsion over the idea of eating horsemeat?

The discovery of horse DNA in burgers in major supermarkets such as Tesco and Iceland has been met with alarm among consumers.

Horse-eating, or hippophagy, spread in Europe in the 19th Century, after famines caused several governments to license horse butcheries.

The meat is still commonly consumed in France and Belgium, as well as parts of Central Asia and South America.

So why are the British so squeamish about eating horse?
