Microbiology of Fluid Milk is a comprehensive textbook developed in accordance with the ICAR 6th Dean’s Committee syllabus for B.Tech. Dairy Technology students. The book provides a clear and application-oriented understanding of the microbial aspects of milk, covering topics such as raw milk microbiota, spoilage, mastitis, hygiene, processing technologies, public health concerns, and microbiological standards. Organized into nine well-structured chapters, it combines scientific depth with practical relevance.

An additional section on laboratory methodologies and principles strengthens hands-on learning in Dairy Microbiology. Designed for students, educators, researchers, and dairy professionals, this book serves as an essential guide for ensuring safe and high-quality milk production.
