Summary A total of fifty blood meal samples were prepared; twenty‐five by the incorporation of calcium oxide in the fresh blood at a ratio of 1:8 and the remaining samples without adding calcium oxide. the most probable number of coliforms and Escherichia coli were recorded to be 3 × 10 2 and 2.3 × 10 2 g −1 respectively in the untreated samples, whereas calcium oxide treated samples did not reveal the presence of coliforms. of the eleven E. coli isolates, five serogroups (O 79 , O 30 , O 25 , O 17 and O 11 ) were identified. the significance of the isolates from the view‐point of human and livestock health have been discussed.
