Strong correlations between clinical signs on farms and the presence of lesions at slaughter have been reported. The objective of this study was to determine if changes in condemnation rates provide a data source for surveillance of disease outbreaks in pigs. The data were obtained from 1 abattoir in Ontario (2005-2007). The epidemiological relevance of the results was based on an outbreak of porcine circovirus associated disease (PCVAD) in Ontario in 2005. The total condemnations and condemnations due to arthritis and pneumonia patterns reflected the field infection of PCVAD in 2005 followed by the widespread use of porcine circovirus type 2 (PCV-2) vaccine in 2007. In contrast, increased rates of nephritis and enteritis suggested areas for enhanced surveillance for unexplained changes in disease patterns not identified through traditional passive surveillance. Further studies looking at the benefits of using abattoir data should compare condemnation patterns with multiple sources of swine health data.
据报道，农场的临床症状与屠宰时病变的存在之间存在很强的相关性。本研究的目的是确定定罪率的变化是否为猪疾病暴发监测提供了一个数据源。数据来自安大略省的1家屠宰场（2005 - 2007年）。结果的流行病学相关性基于2005年安大略省的猪圆环病毒相关疾病（PCVAD）暴发。2005年，因关节炎和肺炎模式导致的总定罪数和定罪数反映了PCVAD的现场感染情况，随后在2007年广泛使用了2型猪圆环病毒（PCV - 2）疫苗。相比之下，肾炎和肠炎发病率的增加表明，对于通过传统被动监测未发现的疾病模式的不明原因变化，需要加强监测。进一步研究使用屠宰场数据的益处时，应将定罪模式与多种猪健康数据来源进行比较。
