The aim of the study was to evaluate the quality of pasteurized milk found in retail outlets. The milk was derived from seven different dairies. Eight parameters of milk were the basis of the evaluation of its quality. The parameters included the following: a) physical - temperature of the milk and its density at the retail outlets; b) chemical - acidity, dry non-fatty weight content, fat, protein, lactosis and water; c) hygienic - presence of inhibitory substances. The evaluation was conducted in accordance with the method proposed by Polish Standards. Significant differences were confirmed between the dairies in all the evaluated parameters. This attests to the differing quality of the raw milk from which milk for consumption is subsequently produced. The quality of milk was also compared with standards from the directives of the Ministry of Agriculture and Rural Development that were valid until January 19, 2008, with those directives that were binding at the time of these investigations from August 18, 2004 concerning veterinary requirements for milk and milk products, as well as in the Polish Standards for milk for consumption, PN-A-86003: 1996. It was found that the milk quality of a certain portion of milk that is available for sale is not in accord with the binding directives. It is milk of a higher level of water, not rarely overly acidic, of a lower level of dry non-fatty weight and fat content than claimed, or containing an unacceptable level of inhibitory substances. The obtained results indicate insufficient quality control of the produced milk on the part of the dairies, and that the units monitoring milk sales do not sufficiently care about the conditions in which the milk is stored.
