Abstract
In Islam there are precepts that certain foods are permitted (Halal), others forbidden (Haram). Pork and alcohol are Haram, because they are regarded as unclean. From these precepts is born a consumer described as "Halal". For Muslim consumers, beef must be certified Halal, it means that the cattle have been slaughtered according to Islamic ritual. In the past, Muslim countries in general produced most of the foods they consume themselves. Those who did not imported the products they needed from other Muslim countries. In France, this market is developing steadily in supermarkets, in addition to traditional butchers, with a multitude of products ranging from frozen food to baby food. However, consumers face the risk of fraud on the certification of halal products. They want at all costs be sure that the products comply with the rules of slaughter and that this is not "fake or false" Halal.
