ABSTRACT
Survival of one strain of enterohaemorrhagic E. coli serotype O157:H7, isolated from milk in Poland, in cultivable and meadow soils at 5oC and 20oC was tested. It was found that the death rate of pathogenic bacteria depends on soil fertility and incubation temperature. At 5oC, in such soils as light loam and loamy silt, with humus content of 2.16% to 3.43%, bacteria died after 140-158 daysof incubation, and in such soils as loamy sand with humus content of ca. 1.50% they died after 70-85 days of incubation. At 20oC, these periods for experimental options mentioned above were 70-90 days and 49-63 days, respectively.
