The environment microbiological assessment concerning a utilisation plant was conducted, basing on the occurrence of Salmonella spp., E. coli and feces streptococci in it. Most of the examined microorganisms were isolated in summer time in the septic part of the plant, that is on the unloading platform, in the dissection room, in the offal container, and in the load-carrying body and tyres of cars transporting carcass. Salmonella spp. occurred 3 times in insignificant quantities. In the non-septic part of the plant the fecal bacteria occurred in the mill room, more infrequently in the sift room and in the engine room. The meat-and-bone meal did not raise any objections in the health-hygienic respect. Among numerous faults, the lack of proper room separation of septic and non-septic parts of the plant calls for particular attention.

Microbiological and parasitologic investigations dealing with the influence of aeration on fecal bacteria and Ascaris suum eggs survival in cattle slurry were carried out. The results showed that already the first stage of aeration (reactor I) eliminated quickly a number of Salmonella senftenberg (105 times during 2.5 hours in relation to the control test) and EHEC (108 times during 2.5 hours in relation to the control test) respectively. The longest survival time was for D group streptococci. Inactivation of Ascaris suum eggs due to thermic conditions fluctuated between 50 and 90 minutes. The final stage of aeration (reactor II) completely destroyed pathogen germs and Ascaris suum eggs present in cattle slurry.
