“…Previous studies conducted on the quality of fresh milk in Kosovo have shown high CFU and SCC values, indicating high level of contamination during milking and storage of milk after milking (Bytyqi et al, 2010). About 24% of milk collected was evaluated as being of poor hygiene, depicting values of more than 500,000 SCC cells/mL and around 50% of the samples had more than 3,000,000 CFU/mL of milk in a study carried out with dairy farms in Kosovo (Bytyqi et al, 2011). The enforcement of the quality standard without intervention in milk preservation and handling infrastructure would take out of business about 90% of the dairy farmers who deliver the milk to the dairies.…”

, 2016. Prevalence and antimicrobial susceptibility of bacterial isolates from subclinical mastitis in dairy farms in Kosovo. Bulg. J. Vet. Med., 19, No 4,[299][300][301][302][303][304][305][306][307] The aim of this study was to determine the prevalence of subclinical mastitis in dairy cows in Kosovo and the antimicrobial susceptibility of isolated bacteria. Six hundred and twenty four milk samples from individual quarters of 156 lactating cows were tested using California Mastitis Test (CMT) and the positive samples were further analysed using conventional methods for isolation of main mastitis causing agents and finally identified using biochemical tests. The overall prevalence of subclinical mastitis was 25.6%. Twenty one mastitis positive cows belonged to Holstein Friesian breed, 11 to Simmental and 8 were crossbred. Regarding age susceptibility, 13 cows resulting positive in the CMT test were 2-5 years of age and the other 27: 6-9 years of age. A total of 112 bacterial isolates were recovered. The most prevalent species were Staphylococcus aureus (28.6%) followed by coagulase negative staphylococci (21.4%), E. coli (13.4%), Streptococcus agalactiae (14.3%), Streptococcus dysgalactiae (3.6%), Streptococcus uberis (6.2%), Corynebacterium spp. (8%), and Bacillus spp. (4.5%). The isolates were subjected to antimicrobial susceptibility test using the disc diffusion method. In vitro tests of bacterial isolates revealed higher sensitivity to amoxycillin/clavulanic acid, oxytetracycline, trimethoprim and gentamicin. The lowest susceptibility was shown to penicillin and streptomycin except for Corynebacterium spp. and Bacillus spp.

“…Currently, regarding bacterial contamination (CFU), the practices and conditions under which small-scale farms and their dairy chains operate make it difficult to produce high quality milk. For SCC, as in the [19], the results obtained that the amount of somatic cells (SCC) in fresh milk from the small-scale dairy farms is relatively acceptable according to the standard in the country. However, there are a lot of variation deriving from different farms (CP) indicating the large managerial divergence, breeds impact, farm infrastructure, and the present structure of animal health control in the country [1].…”

The basic goal of this research was to determine the impact of the presence of bacterial (CFU) and somatic cells count content (SCC) in quality of fresh milk in some small cattle farms in Kosovo. The survey was based on existing standards for milk quality in Kosovo placed under administrative guidance MA-no. 20/2006. The study was based on fresh milk analysis of 150 farms performed during the period September-December 2012, which was obtained in 9 different localities (collection points) of the Kosovo. Our study reveals that CFU and SCC in fresh milk were significantly affected by a number of factors, as: sampling period (repetition), locality, breed, and time of sampling (evening or/and morning). According to the results for CFU and SCC, there were big differences between the farms (milk collection points) included in the study (P < 0.0403) and (P < 0.0293). The results show that small size breed like Busha and its crosses tend to be less exposed to SCC/mL in milk (72.840) and (293.592), compared to Black Holstein (613.462), Simmental (521.519) and Brown Swiss (418.44). Milk produced in evening tended to be of better quality (259.854 CFU/mL) compared to the one from morning milking (576.689 CFU/mL). Fresh milk quality analyzed in the third repetition was better for about 33.3% compared with the repletion first. For CFU and SCC, the analyses show that about 74.7% and 64.7% of milk produced belongs to extra quality, while lower quality of milk of category three is 12.0% and 23.3%, respectively. Considering that about 85% of milk produced in Kosovo comes from small-scale dairy farms, the current study sets out that small-scale milk production system cannot be neglected by interest parties in dairy sector and needs permanent following up and improvement.

In this study, the bacteriological quality and the presence of Staphylococcus aureus, Escherichia coli O157:H7, Bacillus cereus, Salmonella species, and Pseudomonas species were studied in raw milk, cultured milk, milk handlers and packaging containers. A total of 36 samples were collected over 3 months from three different farmers. Samples were analyzed for means of counts per milliliter of milk for total bacterial count (TBC), total coliform count (TCC), total E. coli count (TEC), S. aureus, B. cereus, Salmonella spp. and Pseudomonas spp. Microbial load ranged between 0.81 and 7.6 log 10 cfu/ml for various critical sampling locations. Isolates of E. coli, S. aureus and B. cereus were taken for simple polymerase chain reaction (PCR) to investigate the presence of virulent genes, rfB, sei, and cytK with amplicon sizes of 1.0 kb, 500 bp and 320 bp, respectively. The sei gene was detected in 19% of the samples and 2.8% were found to have the cytK gene. The rfB gene could not be picked in E. coli. The results show poor hygienic practices at the processors and potential risk to the consumers.
