The invention relates to a system and method for processing clusters of poultry viscera, at least comprising a gizzard. The method comprises conveying the clusters of viscera in a suspended manner, pulling the gizzard of each cluster of viscera, while the latter are being conveyed in a suspended manner, over two elongate scraper bodies which rotate about respective rotation axes, each of the scraper bodies comprising at least one scraper element, wherein, due to the rotation of the two scraper bodies, gizzard fat which is present on a gizzard wall is separated from the gizzard by the scraper elements while the gizzard is being pulled, and collecting the gizzard fat which has been separated from the gizzard of the successive clusters of viscera.
