The prevalence and significance of enterobacteriaceae isolates from milk and dairy products

, : The prevalence and significance of enterobacteriaceae isolates from milk and dairy products. South African Journal of Dairy Science 20(1): 23-28

Two hundred and forty nine milk samples and a variety of dairy product samples were analyzed for the presence of coliforms. Only the powdered milk and infant food samples fell within the proposed range of quality standards (< 10 g-1 or ml-1). The mean coliform bacterial counts of the different products were as follows (standards in brackets): cottage cheese 7.14 .times. 101 g-1 (< 10 g-1), yoghurt 9.51 .times. 101 ml, (< 10 ml-2), cream 1.61 .times. 10-2 ml-1 (< 10 ml), ice cream 2.07 .times. 10 (< 10 g-1) and raw milk 7.8 .times. 102 ml-1 (< 100 m-2). The dominant Enterobacteriaceae species isolated from the different dairy products were Enterobacter cloacae (22.4%), Klebsiella oxytoca (18.4%), Citrobacter freundii (18.4%) and Enterobacter agglomerans (13.2%). Better quality control and improved hygiene will be required to ensure the necessary product quality.
