Abstract: A method and a system for decontamination the surface of food items such as meat pieces is described. A method includes obtaining at least one food item and/or at least one meat piece to be surface decontaminated, microwave treating the food item and/or the meat piece with microwaves in the range of 0.5-18 GHz such as 4-18 GHz, wherein the microwave treating is performed on at least one food item and/or meat piece which is packed in a packaging material, and/or the food item and/or meat piece pivot during microwave treating at least along two circular paths.

Abstract: A scoring machine (1) for scoring a surface of an item which is substantially plane in its main dimension and is curved transversely to its main dimension, the item being moved along a transport path (2) in a direction of movement (3), such as a surface of an item being conveyed forwards by means of a number of conveyors (4,5,6), the scoring machine 1 comprising a structure (11) with a curved path (7) of substantially the same curvature as the conveyed item transversely to its main dimension, and a number of scoring devices (14) being mounted on the structure (11) in such a manner that the scoring devices (14) are movable along the curved path (7) extending transversely to both the transport path (2) and the direction of movement (3) of the item moved, which makes it possible to score the surface of items in a uniform manner regardless of the point of time of the working day on surfaces of up to 700 items an hour and in a hygienic manner.
