“…The problem is infections of animals that do not generate recognizable clinical signs during breeding or fattening. Over the last years, a number of reports have been published in Poland concerning the assessment of slaughter animals, as well as the meat of poultry and free-living animals in Poland (Libelt 2001;Radkowski et al 2010;Szkucik et al 2012;Szkucik et al 2014;Lis and Górski 2017a, b). The results of these tests show a significant number of animals for slaughter, especially cattle and pigs with symptoms or lesions.…”

The aim of the study was to analyze and compare the frequency of symptoms and pathological conditions in slaughtered animals in 2009 and 2017, and to determine the reasons behind their presence. The results of official post-mortem assessment of cattle, pigs and sheep carried out by the Veterinary Inspection were analyzed. When analyzing the causes of lesions or pathological symptoms and unfitness for consumption, the following conditions have been included: tuberculosis, actinomycosis, as well as quality deviations: emaciation and watery muscles, icterus, organoleptic changes, incomplete loss of blood, natural death, slaughter in agony, foci of pus, contamination and congestions, as well as other changes and parasitic invasions: cysticercosis, echinococcosis, fasciolosis and trichinellosis. It was found that the number of slaughtered animals exhibiting health condition deviations or symptoms and pathological changes remains at a high level in Poland, and it even demonstrates a slight increase in case of cattle. A large number of contamination and congestions indicates low attention to the conditions of ante-mortem trading in terms of slaughtered animals, as well as to hygiene and conditions for slaughtering, cutting and carcass processing. Quality deviations in the form of emaciation and watery muscles or incomplete loss of blood in slaughtered animals indicate mistakes made during breeding or when transporting the slaughtered animals. Having considered the foregoing, there may be justified concerns about the appropriate level of animal welfare. Parasitic diseases, especially fasciolosis in cattle and sheep, and echinococcosis in pigs in some areas require more effective actions to reduce them. On the other hand, a very small number of cases of trichinellosis in pig meat can be considered satisfactory.

Tumors in boars are uncommon, and testicular tumors even rarer. This study describes the pathological and immunohistochemical characteristics of a case series of testicular tumors in commercial boars with fertility problems. Tumors were detected in 19 of 333 animals (19/333, 5.9%). Macroscopically, tumors were observed in 13 (13/19, 68%) boars, while 6 cases (6/19, 32%) were only detected by microscopic examination. Testicular enlargement was observed in 1 boar, while in the others, tumors were only observed after removal of the scrotal skin or after sectioning of the testis. Histologically, tumors were classified as seminomas (16/19, 84%), mixed germ cell-stromal tumors (2/19, 11%), and B-cell lymphoma (1/19, 5%). Seminomas had 3 different growth patterns: intratubular (6/16, 38%), diffuse (4/16, 25%), and intratubular/diffuse (6/16, 38%). All tumors that were not evident on macroscopic examination were intratubular seminomas. Intratesticular metastases were observed in 2 cases and extratesticular metastases, located in the pampiniform plexus, were observed in 1 case. In 1 seminoma, the rete testis was also involved. By immunohistochemistry, all intratubular seminomas were negative for c-kit, cytokeratin, and vimentin. In diffuse seminomas, c-kit and cytokeratin were also negative, while vimentin showed granular or perinuclear cytoplasmic labeling in some areas. PAX-5 and CD-3 antibodies classified the lymphoma as a B-cell lymphoma. This study suggests that testicular tumors in boars may be more common than previously reported, especially when microscopic examination is performed. It also shows that testicular tumors in pigs are predominantly seminomas.
