Poland exports approximately 8000 tons of venison annually. It is sent primarily to Germany, the Skandinavian countries and Japan. Game meat in Poland undergoes the same veterinary inspection as does the meat of slaughter animals. In the years 1988-1992 a sum of 498 thousand wild boars, 835 thousand roe deer, 207 thousand red deer and moose, 1,175 thousand hares, as well as 2,171 thousand game fowl was hunted. Veterinary inspection was carried out in particular years on 89.6-95.3% of the boars, approximately 97% of the roe deer, from 3.3-18.4% of the hares, as well as 6.9-1.9% of the game fowl. Cases of entire unlit carcasses were determined in 1.08-1.43% of the boars, 0.15-0.27% of the roe deer, 0.40-0.51% of the red deer and moose, 0.19-0.76% of the hares, and 0.65- -1.09 % of the game fowl. Portions of the carcass or internal organs were deemed unfit in the game animals in the following percentages: boars 7.5-26.9% of the animals; roe deer 3.14-16.94%; red deer and moose 4.80-18.48%; hares 0.35-3.06%; game fowl 0.41-1.12%. The most common causes of confiscation were diagnosed diseases of the respiratory tract in 19% of the cases, deterioration in 19.3%, as well as parasitic diseases in 57.2%. Among the parasitic zoonoses, of particular concern is the increasing incidence of trichinellosis in boars. In 1988 the extensiveness of trichinellosis in these animals was 0.29%, in 1992 it was 0.40%. This is approximately a hundred times higher than in domestic pigs, which in the discussed period remained constant at 0.003%. Considering the fact that not all the killed boars are tested for Trichinella spiralis, there in a strong chance that 10,103 boars were not tested. If we accept an extensiveness of trichinellosis invasion up to 0.4% in boars, as took place in 1992, it can be estimated that the meat of 40 not veterinary inspected boars infested with Trichinella was consumed. Among infectious diseases worth noting is the occurrence of rabies, in wild animals as a whole and game animals as well. In the span of the last ten years it has been confirmed primarily in roe deer, but its main source remains foxes.

The aim of the investigations was to determine the variability of saprophytic bacteria contamination of steamed and liver sausages in particular stages of production. The investigations were carried out on meat after deboning and curing, on edible offals, on force-meat after filling the casings and on final products immediately after production and already designated for sale. It was discovered that the bacterial contamination of raw materials for sausage production was relatively high and amounted from 10³ to 10⁵ per gram. Technological thermic operations reduced quantity of microflora to 10² per gram. During transport and sales, however, the total count of bacteria increased rapidly again to 10⁴ per gram. Therefore particular attention must be paid to storage conditions after the production of these types of sausages.

The purpose of the study ^as the hazard analysis of critical control points at the time of milking and the processing of raw milk for consumption, during which the possibility of contamination by microflora and various residues can occur. The milk was selected for investigation during the following stages: after milking in individual dairy farms, from bulk tank milk before and after its transport to the dairy, after pasteurization and from sale for consumption. The following were determined: total count of aerobic bacteria in 1 ml, presence of coliforms and enterococci, acidity, presence of residues of antibiotics, disinfectans and washing media, and somatic cell counts in 1 ml. It was concluded that points of special hygienic hazard for raw milk processed for cosumption were: 1. poor hygienic conditions during milking and storing in individual farms as well as the poor living conditions and health of cows: the individual farm is the first link in the contamination of milk with microflora, residues of antibiotics and washing media, and greater somatic cell counts, 2. mixing of milk of good and poor hygienic quality in collection centres and dairies, in spite of the fact that it is possible to carry out a segragation of the milk, 3. the improper hygienic handling of milk after it has been pasteurized; the improper storage of packages is a secondary source of contamination of milk with microflora, while unthorough washing and disinfecting procedures are an additional source of residues of disinfectants and washing media.
