EXAMINATION OF HEALTH-HYGIENIC CONDITION OF A SELECTED UTILISATION PLANT.
Zbigniew Paluszak, Halina Olszewska, Bożena Szejniuk
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.
Key words: utilisation plants, hygiene, Salmonella, E.coli.
