In Natal, the milk seemed inferior than the milk of the others regions in physical and chemical meaning, as a result we concluded that in this region there was fraud related by addition of water, we also supected a high change in consequence of the mastitis of the herd, and it was noticed the change in the total solids (fat, lactose and protein), probablly because of the effect of the microorganisms presents in a big amount in the milk of this area. In Mossoró we also saw addition of water in the milk, in spite of so much lower than if compared with the milk of Natal.
