AB  - BACKGROUND: Porcine respiratory diseases remain the biggest challenge in 
      pig-based food production and are a public health concern. Despite control 
      measures, persistent outbreaks have been reported worldwide. OBJECTIVE: To 
      establish an early detection mechanism for pig farm disease outbreaks based on 
      slaughterhouse risk and environmental assessment. METHODS: We investigated the 
      prevalence and risk factors of porcine respiratory disease-causing pathogens 
      including Mycoplasma hyopneumoniae (MHP), porcine circovirus type 2 (PCV2), 
      porcine reproductive and respiratory syndrome virus (PRRSV) and Haemophilus 
      parasuis (HPS). Polymerase chain reaction (PCR) was used to analyse the lungs of 
      491 pigs from 19 slaughterhouses across 11 cities in Shanxi Province, China. 
      RESULTS: PCR detected MHP, PCV2, PPRSV and HPS in 76.99%, 67.00%, 11.82% and 
      19.55% of the samples, respectively; 10.12% were negative for all four pathogens. 
      Co-positivity rates for two and three pathogens were identified. The results 
      confirmed significant correlations between PCV2 and MHP (p = .001, p < .05), HPS 
      and PCV2 (p = .01, p < .05) and MHP and PRRSV (p = .01, p < .05). No significant 
      correlation was observed between HPS and MHP (p = .067, p > .05). Positive MHP 
      and PCV2 rates were low in areas with high vegetation coverage. The overall 
      pathogen positivity rate was higher in both lower and higher temperature 
      environments. CONCLUSIONS: Interactions among pathogens may increase disease 
      severity. Furthermore, environmental assessment and pathogen surveillance within 
      pig slaughterhouses can be an effective approach for early detection and 
      mitigation of new disease threats before broad dissemination occurs among a herd.
