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.

A method for decontaminating the surface of at least one meat piece with a non-processed interior, said method comprising the steps of:
- microwave treating at least one meat piece with a non-processed interior with microwaves in the range of 0.5-4 GHz or in the range of 4-18 GHz, wherein said microwave treating is performed on said at least one meat piece, the at least one meat piece packed in a packaging material comprising an active or passive material;
- microwave treating the at least one meat piece for a time period such that the meat surface becomes decontaminated and the interior of the meat piece is not heated substantially;
- and
- obtaining at least one surface decontaminated meat piece with a non-processed interior.
A system for decontaminating at least one meat piece, said system comprising at least one treatment chamber comprising:
- at least one microwave emitting device capable of emitting microwaves in at least part of the range of 0.5-18 GHz;
- and
- means for simultaneously rotating the at least one meat piece along at least two circular paths.
