The Occurrence of Infectious and Parasitic Diseases in Poultry Slaughtered in the District of Olsztyn, Poland, 1986-91

Abstract

During 6 years, 1986-91, in poultry processing plants in the district of Olsztyn, Poland, 37,779,959 carcasses and internal organs of slaughtered fattened poultry were (1,691,188 hens, 23,681,855 chickens, and 12,226,016 turkeys) were examined. As a result of the antemortem and postmortem inspections, 744,499 birds were condemned for human consumption, which was 1.66% of the total number of birds examined. The highest percentage of condemned birds was registered in hens (2.4%) and the lowest in chickens (1.27%). By means of a medical examination, the following diseases were diagnosed most frequently in chickens: Marek's disease in 2,265 birds (0.095%), salmonellosis in 13,463 birds (0.056%), coccidiosis in 9,548 birds (0.04%), and chronic illness of the respiratory system in 377 birds (0.0016%). In hens, salmonellosis was found in 15,951 birds (0.94%), tuberculosis in 301 birds (0.018%), leukemia in 122 birds (0.007%), and aspergillosis in 71 birds (0.0042%). In turkeys, chronic illness of the respiratory system was found in 23,938 birds (0.196%), aspergillosis in 13,243 birds (0.11%), salmonellosis in 3,918 birds (0.032%), and leukemia in 29 birds (0.00024%).

Histopathology in diagnosis of broiler chicken and layer diseases – review of cases 1999-2010

“…Similarly to other research the incidence of avian leukosis (AL) among all birds (up to 2%) was low and also less frequently noted than MD (Balachandran et al 2009); however, in some reports AL was even more rare (Radkowski et al 1996). In our own study, the mean age of layers was in agreement with an earlier report (Balachandran et al 2009).…”

“…These results are similar to findings obtained in other studies, where peripheral nerve infiltration was observed only in layers (2.8%) (Wieliczko et al 2002). In another retrospective study MD was noted less frequently (0.1%) in chickens from the north-east of Poland (Radkowski et al 1996). Interestingly, our results were similar to those (3.03%) obtained in a histopathological survey conducted on other continent (Balachandran et al 2009).…”

“…Investigations conducted in the district of Olsztyn (Poland) lasting 6 years indicated coccidiosis in 0.04% birds, ranked 3 rd among poultry diseases (Radkowski et al 1996). In the present study such cases occured occasionally.…”

“…Generally, lesions in the upper respiratory tract including inflammatory process were diagnosed as nonspecific tracheitis and, according to the literature, were commonly found in poultry in Poland and world-wide (Radkowski et al 1996, Chacón et al 2007). Additionally, in the present study a few cases of ILT were noted, occasionally in layers, but some authors emphasize that these cases are more frequent (Chacón et al 2007); however, in the cited paper a definitive diagnosis was based on PCR or ELISA.…”

Survey of Poultry Carcass Condemnations in Abattoirs of West Azerbaijan Province (North West of Iran)

“…Septicemia, also known as toxemia, is a general condemnation category that includes clear signs of systemic disease involvesecond common reason was cachexia (25.7%). A survey of poultry carcass condemnation was carried out in Poland, 1986Poland, -1991 carcasses were examined and 1.66% was condemned and the most common reason for condemnation was Marek's disease (Radkowski et al, 1996). In England and Wales, 1992-1993, 1.3% of slaughtered broilers were condemned and septicemia/toxaemia/fever was the most common causes of condemnation (Bremner, 1994).…”
