Abstract

The personal hygiene and health of milkmen improvement influence on the milk safety and composition on 128 small household farms in different regions of Serbia, producing mostly milk, having 5–15 cows, a milk cooler and at least one milking machine, was evaluated during six visits, by the following indicators: 1. the state of hands hygiene, 2. the condition of clothing hygiene and footwear, 3. gloves wearing and hygiene, and 4. regularity of the health check of milkmen, rated on a scale of 1 to 5. The samples were taken during visits after cooling and tested for milk protein and fat content, somatic cell count (SCC) and the total number of microorganisms (TNM), using Gerber method, Kjeldahl method, Fossomatic TM and ISO 4833-1:2013 methods, respectively. The IBM SPSS program was used for statistical data processing. A trend of continuous improvement of all hygienic values was observed in relation to the ordinal number of visits, еxcept for indicator 3 (wearing and hygiene on gloves), when deterioration during the fourth visit compared to the previous was observed. No significant differences were found between the farm visits for indicator 4 (regularity of the health check of milkmen). TNM mean scores increased significantly after every visit (F=9.63, P<0.0001). SCC scores varied very significantly between visits (F=5.17, P<0.0001). The number of visits tended to show a significant influence on the milk fat rate (F=2.221; P˂0.1).
