Additional file 3: Proposal of the potential use of each cluster to define indicators for future statistical analysis.
Only “stable” clusters are presented.
Cluster
Brief description
1
Faecal contamination of heart or lungs
linked with failure during evisceration
step
Alterations linked to failure in the
slaughtering process
Pericarditis and bronchopneumonia
which could be linked to traumatic
reticulo-pericarditis
Fatty liver syndrome
Lung emphysema : farmer’s lung
Chronic liver lesions
Chronic peritonitis lesions which could
be linked to previous infection
