The aim of the study was to determine the influence of temperature, i.e. 4 and 20oC on the Escherichia coli O157:H7 survival time in a stored cattle slurry in a laboratory model experiment. The results of this investigation indicated that the tested microorganisms underwent a gradual elimination in the cattle slurry, whereas their inactivation rate was clearly dependent on the temperature. A higher survival rate was found in Escherichia coli O157:H7 at 4oC where a theoretical survival time of these microorganisms, determined using a regression analysis, amounted to 83 days. Our study indicates that there is a necessity for the slurry to undergo hygienization processes and that a constant monitoring of liquid animal excreta in search for pathogenic microorganisms is required.

In recent years there has been a growing interest in hazards having a microbiological source, resulting from the direct transmission of microorganisms from the natural environment, which may result in inducing diseases in people and animals. This study aimed at determining the survival of pathogenic bacteria Listeria monocytogenes in water and sewage from the meat industry plant, depending on diversified temperature conditions, as well as the assessment of sanitary and epidemiological risks resulting from the ability of determined microorganisms to live in a water environment. On the basis of our research, it was found that Listeria monocytogenes showed the longest survival time both in water and sewage at 4ºC, where the maximal survival time of those microorganisms determined on the basis of the regression analysis amounted to 120 and 141 days, respectively. The results obtained in the experiment present important data concerning the survival of the bacteria Listeria monocytogenes in sewage and the water environment, and at the same time they draw attention to the need for a constant monitoring of effluents from the meat industry plant, as well as the surface waters within the range of influence of those facilities on pathogenic and potentially pathogenic microorganisms.

Badania prowadzono w latach 2005-2006 na terenie Stacji Badawczej w Mochełku, należącej do Uniwersytetu Technologiczno-Przyrodniczego w Bydgoszczy. Ich celem było określenie stopnia przeżywalności oraz tempa inaktywacji bakterii wskaźnikowych Salmonella Senftenberg W775 w glebie w zależności od uprawy wybranych roślin rolniczych. W eksperymencie rolę nośnika pałeczek Salmonella Senftenberg W775 pełnił kompost z odpadów komunalnych, który wprowadzono do środowiska glebowego na poletkach doświadczalnych w uprawach rolniczych owsa, mieszanki owsa z łubinem żółtym, żyta jarego oraz mieszanki żyta jarego z łubinem żółtym. Przeprowadzone badania wykazały, że tygodniowe tempo eliminacji Salmonella Senftenberg W775 w glebie, w zależności od poszczególnych upraw polowych, przyjmowało wartość od 0,33 do 0,46 log, natomiast maksymalny czas przeżycia wykrywanych drobnoustrojów wynosił od 18 do 24 tygodni.

The aim of the present research was to determine the survival rate and the rate of inactivation of indicator bacteria Salmonella Senftenberg W775 in soil, depending on the cultivation of selected agricultural crops. The research was carried out over 2005-2006 at the UTP Experimental Station at Mochełek. In the experiment the role of the carrier of Salmonella Senftenberg W775 bacilli was played by communal waste compost introduced into the soil environment, on experimental plots with agricultural plantation of oat, mixture of oat with yellow lupine, spring rye and a mixture of spring rye with yellow lupine. The present research demonstrated that the weekly elimination rate of Salmonella Senftenberg W775 in soil, depending on respective field crops, ranged from 0.33 to 0.46 log, while the maximum survival time of detectable microorganisms – from 18 to 24 weeks.
