The purpose of this study was to analyze the results of post-mortem examinations of horse carcasses conducted by the Veterinary Inspectorate in the years 2001-2010 in Polish slaughterhouses for these animals. In this period, 377,000 horses were slaughtered. Morbid traits or qualitative changes were observed in 60,327 carcasses, constituting 15.99% of all carcasses examined. The number of carcasses judged unfit for consumption was 1,099, i.e. 1.82% of those in which morbid traits or qualitative changes had been detected (or 0.29% of all carcasses examined). The most common were qualitative changes: most of these were described as pollution and congestion, found in 43,623 carcasses, i.e. 98.5% of carcasses departing from quality standards or 11.57% of all carcasses examined. A small proportion of all carcasses examined (0.05%) were affected by microbial infections. This group of diseases consisted of only three disorders: tuberculosis, sepsis and tetanus. Parasites were found in 10,011 carcasses examined, but only 1 carcass was judged unfit for consumption (a case of trichinosis diagnosed in 2010). The most frequent reasons for classifying carcasses as unfit for consumption were sensory changes (31.48%). Beginning from 2002, the number of carcasses judged unfit for consumption systematically decreased while the number of slaughtered animals increased. Two minor departures from this pattern were observed in 2006, when the proportion of carcasses deemed unfit for consumption increased by 0.07% compared with 2005, and in 2008, when the number of slaughtered animals decreased. Compared with the period 2001-2009, the proportion of carcasses with morbid traits increased abruptly in 2010: it was six times greater than in 2009 and three times greater than in 2001, i.e. in the two years when, as in 2010, over 40,000 horses were slaughtered in Poland. Moreover, in the last of the ten years under examination there was a notable increase in the number of qualitative changes, parasitic lesions and carcasses with a negative sanitary assessment. This increase may have been caused by a deterioration in the quality of slaughtered animals combined with the rigorous performance of post-mortem examinations by official veterinary surgeons.
The aim of the study was to analyze the results of postmortem examinations conducted by the Veterinary Inspectorate on sheep and goats in Polish slaughterhouses in 2003-2013. During this period, over 260,000 sheep and goats were slaughtered, of which 0.8% were slaughter goats. In 92,050 carcasses, that is, in 35.21% of all carcasses examined, pathological lesions or quality changes were found. Only 448 carcasses, that is, 0.49% of carcasses with pathological lesions or quality changes, and 0.17% of all carcasses examined, were judged unfit for consumption. The most frequent lesions were parasitic invasions (49.69%) and purulent foci (47.96%). On the other hand, the most common causes of the rejection of carcasses as unfit for consumption were natural death or slaughter in a moribund condition (41.52%), followed by purulent foci (13.39%) and emaciation (11.16%). In the past 11 years, there have been only 23 cases of scrapie (5.13% of carcasses unfit for consumption). Since 2010 there has been a systematic decrease in the number of carcasses showing pathological lesions, and since 2009 there has been a decrease in the number of carcasses diagnosed with parasitic invasions, and at the same time no meat has been rejected on this ground. What was characteristic of this period was a small number of lesions caused by microorganisms, and, since 2004, a decreasing number of carcasses with qualitative changes, including excessive emaciation and insufficient bleeding, hydraemia, jaundice, organoleptic anomalies, incomplete bleeding, natural death or slaughter in moribund condition, purulent foci, contamination, and congestion.
