title: Poultry abattoir survey of carcass condemnations in Fars province, southern Iran.
abstract: Official post-mortem inspection records of poultry in 11 industrial poultry abattoirs in the Fars province, southern Iran, between 20 March 2002 and 19 March 2006 were used to investigate the character and prevalence of poultry loss caused by disease and pathological changes in the province. Linear regression analysis for study of time trend and chi2-test for investigation of seasonal pattern were used as statistical methods. In the study period, 130,967,021 birds were slaughtered. As a result of official veterinary inspection, 959,416 (0.73%) birds were condemned. The condemnation risk was calculated for each quarter in a year. Cachexia and septicemia were the most common reasons for rejection of carcasses and were responsible for 62% of the total condemnations. The condemnation risk due to septicemia increased over the study period from 0.14 to 0.22%. The rejection risk due to overscalding declined over the study period from 0.07 to 0.01%. No trends in time were observed for the other causes of condemnation. In conclusion the majority of condemnations are caused by disease and improving the standard of disease prevention and control on farms is necessary. These results could form the basis of an assessment of trends in condemnations in poultry slaughterhouse and should prove useful to the poultry industry as a baseline data for future comparison.
