| Isolation Escherichia coli O157:H7 from dairy raw milk samples |
| Microbiological screening tests for the presence of E. coli O157:H7 were carried out on 196 samples of raw cows's milk from different dairies in the East-Slovak region in the period of May-July 2006. Of the total number of examined samples, E. coli strains were isolated from two milk samples (1.02%) from dairies of the Trebiov district. In spite their relatively low incidence, the health consequences of the presence of this pathogen are so important that regular screening of raw milk seems to be necessary to determine the source and way of contamination as well as to make proposal for effective eliminative and precautionary measures. |
