Milk and its derived products are vital components of the human diet, providing essential nutrients. However, their rich composition and neutral pH make them highly sceptible to microbial contamination and proliferation, posing significant risks to public health and economic stability. Effective microbiological quality control throughout the dairy production chain, from farm to consumer, is therefore paramount. This abstract outlines the critical aspects of ensuring the microbiological safety and quality of milk and milk products. It encompasses the sources of microbial contamination, including the animal, environment, processing equipment, and human handling. Key spoilage microorganisms and pathogens commonly associated with milk and milk products, such as Escherichia coli, Salmonella spp., Listeria monocytogenes, Staphylococcus aureus, and various psychrotrophic bacteria, are highlighted. Furthermore, this abstract discusses the diverse range of microbiological testing methods employed for quality assessment, including traditional culture-based techniques, rapid methods like PCR and ELISA, and emerging technologies. The importance of Hazard Analysis and Critical Control Points (HACCP) and Good Manufacturing Practices (GMP) in preventing and controlling microbial contamination is emphasized. Ultimately, robust microbiological quality control measures are essential to guarantee the safety, extend the shelf life, and maintain the nutritional value of milk and milk products for consumers.
