Abstract: A method for treating a product suitable for human consumption, in particular a meat product, such as for example slaughtered poultry or parts thereof, in which method:—a large number of products are successively supplied, optionally in groups, to an inspection station; and—each product is subjected to a visual inspection in the inspection station, in such a manner that, for example, a visually detectable defect on the respective product is detected. On the basis of the visual inspection, a decision is made as to whether the respective product should be subjected to a specific additive-addition treatment. The products to be subjected to an additive-addition treatment are successively supplied to an additive-addition station, where the products are successively subjected to an additive-addition treatment and an additive is added to at least one part of the outside of each product or the inside of each product.
