The quality is difficult to define because it is a mix of sanitary, technological and organoleptic components. In Europe are different kinds of products: in the Central and Northern parts lambs are produced, on the contrary in the Mediterranean regions heavy, light and milk lambs are more popular; the first one’s are classified according to SEUROP grid and the other by the A grid. The countries where some special carcass classification methods developed are: Sweden, Netherland, UK and Scotland. Anyway in France, Sweden, Finland and German the SEUROP classification it’s a statutory requirement. Around the world a big effort on this topic has been made by the big producers such as Australia and new Zealand in order to find a grading system able to define the price according to the carcass quality.
