The study assessed the quality of raw cow’s milk intended for processing and retail sale (n = 595 samples and n = 19 production batches, respectively) and the relationship between the number of somatic cell and the fat and protein contents. All milk samples were tested for total bacteria count, somatic cell count, antibiotic residues, and fat and protein contents. Additionally, raw drinking milk samples were tested for counts of Enterobacteriaceae, Escherichia coli, coagulase-positive staphylococci, enterococci, and the presence of Listeria monocytogenes and Salmonella spp. In raw milk samples, TBC, SCC, and fat and protein contents ranged from 4.9 × 103 to 2.3 × 105 CFU mL–1, from 9.9 to 407.8 thou. mL–1, from 3.2% to 5.9% and from 3.0% to 4.8%, respectively, while TBC, SCC, and fat and protein contents in raw drinking milk samples ranged from 1.8 × 106 to 3.3 × 106 CFU mL–1, from 454 to 696.9 thou. mL–1, from 1.7% to 2.9% and from 3.1% to 3.4%, respectively. The mean counts of Enterobacteriaceae, E. coli, coagulase-positive staphylococci, enterococci in raw drinking milk were 4.0 × 105 CFU mL–1, 1.4 × 102 CFU mL–1, 2.4 × 104 CFU mL–1, and 2.2 × 105 CFU mL–1, respectively. L. monocytogenes, Salmonella spp., and antibiotic residues were not detected in any of the samples tested. The study showed that 95% of the raw milk samples were of satisfactory quality, while 100% of the raw drinking milk samples were of unsatisfactory quality in relation to the regulatory thresholds. Additionally, raw drinking milk samples were a vehicle of potentially pathogenic bacteria. The somatic cell count did not affect the fat and protein content in the analysed milk.
