Analysis of bovine postmortem condemnation data in France: Contributions from a comprehensive and standardised...

The condemnation of carcases and offal unfit for human consumption is a regulatory requirement at the slaughterhouse. Condemnation data, if comprehensive and standardised, can be a valuable source of information for risk-based inspection and decision making.

The aim of this study was to analyse postmortem condemnation data that were recorded in all bovine slaughterhouses in mainland France from 1 January 2016 to 31 December 2020 in a comprehensive and standardised information system. The rates of and reasons for condemnation, as well as factors influencing rate variation, were investigated through descriptive analysis and multivariable logistic regression models.

The global, total and partial condemnation rates were 4.5%, 0.7% and 3.8% for adult cattle and 1.4%, 0.3% and 1.1% for calves, respectively. Reasons for condemnation varied with the animal category; for example, the three main reasons for total condemnation in adult cattle were serous infiltration of connective tissue (49% of condemned animals), congestive peritonitis (12.2%) and fibrinous peritonitis (10.9%), whereas the top three reasons for partial condemnation were unique abscess (21.9%), haemorrhagic infiltration (20.6%) and muscular sclerosis (17.4%). Condemnation rates were influenced by animal-related factors (sex, age, type of breed) and slaughterhouse-related factors (status, type, slaughter volume).

Our findings could usefully contribute to the continuous improvement of the harmonisation of inspection decisions and support the risk manager's strategy in the modernisation of official controls at the slaughterhouse.
