The microbiological quality of raw milk is key to the quality production of dairy products. Alternation is a term that describes the change of composition, taste and smell at those points where it is inedible for the consumer. Microbial alternation of milk often involves degradation of proteins, carbohydrates and fats of organisms and their enzymes. Milk and dairy consumption has increased considerably in Kosovo over the last decade, and a large part of local production comes from small-scale distributors across the country. In this research, 50 milk samples were taken at some of the cumulative sites and from dairy farms in three Kosovo municipalities (Prishtina, Lipjan and Rahovec). The microbiological quality of the milk samples is analyzed according to official standards. Further, in raw milk, a number of aerobic mesophilic bacteria and number of coliforms were analyzed. Aerobic mesophilic bacteria in fresh milk, used as raw material, did not show more than 2.0×10 6 cfu / ml, whereas coliforms were presented at 4 cfu / ml

Salmonella Enteritidis represents a group of bacteria known to cause typhoid fever, food poisoning, gastroenteritis, enteric fever, and other diseases in humans. People are mainly infected with contaminated water or foods, especially meat, chicken meat and eggs. Salmonella gender includes over 2300 bacterial serotypes. Salmonella enteritidis and Salmonella typhimurium are responsible for over 50% of all infections caused in people anywhere in the world. The purpose of the study is to determine the sensitivity and resistance to antibiotics of some isolated strains of Salmonella enteritidis in private farms and eggs for egg production in several parts of Kosovo. Isolation and identification is done according to ISO 6579: 2002. The antibiotic test was performed on 13 strains of Salmonella enteritidis with the Kirby-Bauer method. Disk diffusion test method must be in compliance with the standard of CLSI clinical institutes and laboratories. Mueller Hinton agar was used with antibiotic disks of various groups where we obtained these results in sensitivity and resistance:
