[Working conditions and psycho-physical predisposition of the personnel of the Veterinary Sanitary Inspection on detection of cysticercosis in cattle in the slaughterhouses].

Investigations were carried out in 8 industrial slaughter-houses and 19 co-operative slaughter-houses in Wielkopolska regional districts. Environmental conditions concerning the work of the personnel of the Veterinary Sanitary Inspection directly occupied on the posts of investigation of cattle after slaughter were estimated. The mentioned veterinary workers were subjected to general-medical, ophthalmic and psychological examinations in the co-operative of Provincial Specialistic Dispensaries in Poznań. Furthermore, during the period of 2 1/2 years in a selected industrial slaughter-house the influence of individual personal features of veterinary workers on the detection of Cysticercus bovis in investigations on cattle after slaughter was studied. On the ground of the investigations presented a distinct correlation between the obtained results of ophthalmic and psychological investigations and the general sanitary condition of veterinary workers as well as the quality and intensity of lighting in slaughter-houses and the effectiveness of investigations on cattle after slaughter on the presence C. bovis was found. The percentage of the detected cases of the cattle cysticercosis was 7 times higher in industrial slaughter-houses than in co-operative slaughter-houses in regional districts. The performed investigations on the influence of individual personal features of veterinary workers on the detection of C. bovis in selected industrial slaughter-houses--have shown essential differences concerning the effectiveness of these investigations after slaughter carried out by individual persons, who detected cysticercosis during the investigation of heads from 0,40 to 3,58%, inner organs (hearts, lungs and so on) from 0,08 to 1,71% and carcasses of cattle from 0 to 0,08%. From the above observations it appears, that a proper selection of persons as well as a current individual estimation of the work of the sanitary-veterinary supervision are also essential elements stimulating the detection of cattle cysticercosis.
