Abstract

Milk and its products can harbor a variety of microorganisms and can be important sources of food borne pathogens. The presence of food borne pathogens in milk is due to direct contact with contaminated sources in the dairy farm environment and to excretion from the udder of an infected animal. The foodborne pathogens can reach humans by direct contact, ingestion of raw contaminated milk or cheese, or contamination during the processing of milk products. Isolation of bacterial pathogens with similar biotypes from dairy farms and from outbreaks of human disease substantiates this hypothesis. This study was conducted to determine the incidence of some pathogenic micro organisms in bulk tank milk from 3 dairy farms in Gharbia governorate, Egypt. Staphylococcus aureas, Streptococcus agalactiae and Escherichia coli were detected with percentages of 37.5, 6.25 and 12.5% in examined bulk milk samples collected from farm I, 25, 12.5 and 25% from farm II and 12.5, zero, and 12.5% from farm III., respectively. The presence of these pathogenic microorganisms in bulk tank milk contribute a potential risk to public health, these findings underscore the need to control them and to limit bacterial multiplication in bulk tank milk.
