Raw milk sales are legal in 30 states, including Mississippi, where regulations are largely management-based and not food-safety related. The research objectives were to analyze the microbial profile of raw goat milk from Mississippi farms and assess food safety practices and perceptions of dairy goat farmers. Deficiencies and opportunities for improvement in raw goat milk safety were identified. Staphylococcus spp. was present in most (70%) milk samples but aligned with drying-off. E. coli, Enterobacteriaceae, and coliforms were observed in 4, 10, and 12 samples, respectively; no Salmonella spp. or Listeria monocytogenes were detected. The survey highlighted farmers' need for educational opportunities on safe milk handling with emphasis on handwashing. Most producers (80.8%) are willing to invest more in their farms, creating strategic opportunities for extension outreach to help with market expansion and sustainability. Overall, training accessibility could help producers nationwide by encouraging safe milk handling and best management practices.

This book provides the view of the Dairy production and prevailing constraints associated with cow milk hygiene, the hygienic conditions of cow's milk and the microbial load of raw milk, milk-borne bacterial pathogens at farm level and selling points and the possible fecal contamination of milk produced by dairy farmers in Hawassa city. The bacteriological quality of the pasteurized milk from selling points and water source used for cleaning milk and milk product handling equipments also combined to see overall quality of the marketable fluid milk in the city. The overall aim of the present work is to contribute to the effort towards improving the quality of raw milk through providing information on quality and safety of raw milk produced and marketed in Hawassa city.
