The primary purpose of this research was to examine the bacteriological properties of raw ovine milk produced by Merino, Tsigai, Dorper, Lacaune, and British Milk Sheep flocks on four sheep farms located in the eastern part of Hungary. In addition to individual raw milk (IRM) and bulk tank milk (BTM) samples, the udder surface (US) of ewes was also tested for bacteriological quality. A total of 77 US, 77 IRM, and 10 BTM samples were collected in the early morning during regular milking sessions. The samples, kept cooled at temperatures below 4 °C, were delivered to the microbiological laboratory and were examined immediately. The relatively low numbers of bacteria in both US and IRM samples reflected good housing conditions of ewes kept on the four farms studied. However, BTM samples had up to 3.5–4.0 log10 CFU/mL higher mean bacterial counts than their IRM counterparts, and the mean levels of bacteria in BTM on two farms even exceeded the regulatory limit of 6.18 log10 CFU/mL. Further studies need to be performed to clarify this issue.

Factors Associated with Hygienic Quality of Bulk Tank Milk Produced in Central PolandThe aim of this study was a complex analysis of organizational and technological factors affecting somatic cell count (SCC) and total microorganism count (SPC) in bulk tank milk produced in the area of Łódź Voivodeship. The study was conducted on the basis of a questionnaire completed directly in 205 family farms, maintaining Polish Black-and-White Holstein-Friesian cows. The data were analysed statistically using multifactor analysis of variance. The following factors decreased SCC in milk: application of mechanical ventilation in the cowshed; disinfection of stalls for cows; frequent inspection of milking equipment efficiency by a specialized service (twice vs. once a year); application of manual pre-milking udder massage; dry period of a standard length of 6-8 weeks (vs. 2-5 weeks); application of concentrates in amounts of at least 3 kg/day/cow; application of meadow hay and straw or hay only among roughages in cow feeding (vs. straw only); addition of vitamin E and Cu to feeding ration for cows and individual housing of replacement heifers between 1-3 months of age (vs. group system). In turn, the following factors decreased SPC: participation of milkers in specialist trainings; cleaning of teats before milking using wet towel or washing with water containing a disinfectant; "dry" storage of milking equipment between milkings; culling of cows due to mastitis; application of vitamin A and Zn; no use of milk from mastitic cows in calf feeding; and individual housing of replacement heifers during the first month of life.

The objective of this study was to probe the contribution of streptococci to the microbial quality of raw milk. Over a 5-month period, bulk tank milk samples from 48 New York State dairy farms were analyzed qualitatively for bacterial ecology and quantitatively for total bacterial, streptococcal, staphylococcal, and gram-negative bacterial counts. Linear regression analysis was used to determine the contribution of differential counts to total bacterial counts. Streptococci, staphylococci, and gram-negative bacteria accounted for 69, 3, and 3% of total bacterial count variability, respectively. Randomly selected Streptococcus isolates from each bulk tank milk sample were identified to species by means of the API 20 STREP identification system. The most commonly identified streptococcal species were Streptococcus uberis, Aerococcus viridans, and Streptococcus agalactiae, which were detected in 81, 50, and 31% of 48 bulk tank samples, respectively. For five herds, S. uberis isolates from bulk tank milk and individual cows were characterized by PvuII ribotyping. A farm-specific dominant ribotype was found in each bulk tank sample, and that ribotype was isolated from at least one cow within each herd of origin. Bacteriological and strain typing data indicate that control of streptococci, specifically mastitis-causing species, is important for improvement of the microbial quality of raw milk in New York State.
