“…Also, during milking, cooling, storage, and processing, sterile milk from the udder of a healthy cow becomes infected. A possible explanation is that not only cows, equipment, and milking routines are involved in milk contamination, and herd health plans designed for better milk quality must consider milking personnel as one of the factors [26]. Pathogens can be introduced directly into milk by milk-handling workers (milkers), especially if they are careless, ignorant, or deliberately negligent, Farm workers should be in good health and understand the value of hygiene because organisms can be present on the milker's hands, nasal cavities, mouth, skin, and gastrointestinal tract [4].…”

Control of diseases in dairy farms is based on various management factors, such as separation of dairy farms from other domestic and wild animal species, control of human circulation and contact with cows, cleaning and disinfection of vehicles, equipment, surfaces, and other unanimated secondary sources of contamination, feed and water hygiene, waste management, and management of technological processes (e.g., calving management, colostrum management, and milking management). In dairy farms, the milking parlour surfaces should be cleaned regularly and disinfected twice daily to avoid the multiplication of pathogens. Some biosecurity measures that can prevent the spreading of mastitis in dairy farms are the use of personal protective equipment (e.g., milkers’ gloves and milker overall), treatment of all infected quarters at the end of lactation (blanket dry cow treatment), removal of udder hair (shaving or singeing), and washing unclean udders. This chapter details biosecurity and hygiene solutions in the cattle milking parlour.

Introduction. This study aimed to evaluate the quality of milk produced by six cattlemen’s associations in small, isolated farming communities of Carchi, Ecuador. It involved a herd of 814 cows and lasted eight consecutive months. Another aim was to propose a suitable methodology for milk quality evaluation. Study objects and methods. All milk samples were analyzed for total solids, protein, fat, acidity, density, total bacterial count (TBC) and somatic cell count (SCC). Each sample was subjected to an extended qualitative methylene blue reduction test (MBRTe) for which 10 mL of milk, with 0.5 mL of methylene blue, was incubated at 37°C for 24 h. Results and discussion. As a result, we obtained the following types of clots: MBRTe-I (homogeneous solid/liquid clot), MBRTe-II (lumpy clot), MBRTe-III (gaseous clot) and MBRTe-IV (lumpy + gaseous clot). The study showed significant differences in the quality of milk between different associations, suggesting that some of them did not comply with good practices of milking, handling and storage of fresh milk. The quality of milk was classified as good in one association, as regular in another association, and as low in four associations. The MBRTe classified 37% of the samples as MBRTe-I, 18% as MBRTe-II, 14% as MBRTe-III and 12% as MBRTe-IV. Of the MBRTe-I samples, 95% showed the TBC and SCC values of first quality milk. The MBRTe-II had the TBC values of first quality milk, but exceeded the SCC, while the MBRTe-III had good SCC values, but exceeded the TBC. Finally, the MBRTe-IV samples exceeded the permissible levels of both TBC and SCC. Conclusion. It was proved that the MBRTe can help milk producers evaluate the quality of milk and alert them to the possible presence of mastitis in the herd. The MBRTe is a reliable and cheap method that is quick and easy to perform.
