| Abstract | ||
| This study evaluated the safety and quality of raw buffalo milk marketed in Cairo Governorate, Egypt, through analysis of 80 samples collected from four main regions over one year (October 2023–October 2024). The assessment included chemical composition, adulteration detection, microbiological quality, and heavy metal contamination. Results showed 30% of samples contained added water adulteration, and 37.5% did not meet the fat content standards. Microbiological analysis indicated all samples were free of Brucella spp., with somatic cell counts within acceptable limits, reflecting good udder health and hygienic practices. Heavy metal testing revealed no mercury, tin, or arsenic, but 33.75% of samples exceeded permissible lead levels, especially in the Eastern region, raising environmental and health concerns. These findings highlight the need for ongoing monitoring, improved regulatory enforcement, and education to ensure milk safety and quality for consumers in Cairo Governorate. | ||
