TL;DR
A new system for meat inspection in pigs provides more detailed health data to help improve herd management and animal welfare.
Contribution
A multi-level system for recording lung and pleura alterations in slaughtered pigs was developed and tested for usability.
Findings
Low-grade lung alterations were most common (28.4%), followed by moderate (11.3%) and high-grade (5.2%).
Most carcasses (88.9%) showed no pleural alterations, with low-grade pleurisy being the most frequent (4.7%).
The new system was implemented efficiently without extra time and provided heterogeneous health data across batches.
Abstract
Official veterinarians inspect meat to ensure that it is fit for human consumption; however, the meat inspection reports provided to farmers are currently limited to only yes/no answers for several pathological findings. A more detailed and standardized system for data collection is needed to increase the usefulness of the information for the primary sector. In this work, a multi-level recording system for alterations of the lungs and the pleura (no changes, low-grade, moderate-grade, and high-grade alterations) was developed. Trained staff applied this system to 20,345 carcasses slaughtered at four different abattoirs located in two different federal states of Austria. Data for 408 batches from 318 different farms were recorded in total. The analysis of the data obtained showed that frequency of pulmonary and pleural alterations was quite heterogeneous between the slaughter batches. It…
