Mastro Beef – Our Logo “Mastro Beef” is our seal of control and selection of our best meat. We can select for you Heifer, Young Bull and Cow meat based on fat, weight and marbling. Our three “S-words” tell you the story of our Beef.

Safe – As part of the OSI group we are extremely careful when it comes to Hygiene and Safety practices. We are one of the largest world Beef producer and we are always on top of all practices and routines when it comes to Food Safety.

Selected – Thanks to a team of butchers trained in meat selection, we guarantee control and selection by colour, fatness and size. We have therefore created two boxes that differ according to the type of selection: the blue box reflects the European quality standard, while the black box is our premium choice.

Superior – as explained in the section below “Cultivate” – we have a unique and special relationship with thousands of farmers in Poland which allows us to create a unique partnership with them, guaranteeing the fairly treatment and the respect of all Animal Welfare Higher Standards.
