“…Furthermore, it was noticed several times that the trachea was accidentally cut by the operators when separating the viscera for post-mortem inspection, which would have led to unreliable results. However, a recent survey performed in Colombia concluded that abattoirs performing horizontal bleeding had a higher percentage of cutting trachea than abattoirs performing vertical bleeding [31].…”

Agonic aspiration of blood (AAB) may result from an inadequate exsanguination with accidental trachea severing, that can be favoured by ineffective stunning of pigs (Sus scrofa domesticus). This study aimed to evaluate AAB as an animal-based indicator of electrical stunning ineffectiveness, which could be used by official veterinarians during the post-mortem inspection of pigs. Information on 3584 finishing pigs was collected at a Portuguese abattoir that performs head-to-body electrical stunning with horizontal bleeding. Of them, 15.5% of the pigs presented signs of ineffective stunning. AAB lung lesions were found in 27.8% of lungs. Despite what was predicted, a strong correlation was found between well stunned animals and the presence of blood lesions in lungs (p = 0.006). Statistical significances were found between pigs’ lateral recumbency at the conveyor and the presence of blood affecting one lung. Under the conditions of this study, the authors cannot point to AAB lung lesions as an animal-based indicator of electrical stunning ineffectiveness. Further studies should be conducted to establish a better understanding of the causes of aspiration of blood, in particular how horizontal bleeding may affect the occurrence of similar lesions.

“…Slaughterhouse workers are involved in the slaughter of >70 billion animals, annually (Slade & Alleyne, 2022); however, studies on workers' perceptions of animal welfare are limited, and virtually no studies have examined human-animal interactions from the workers' perspective (Hemsworth, Rice, Hemsworth, & Coleman, 2021). Animal welfare research at the slaughterhouse level often has focused on the influence of workers on the efficiency of certain pre-slaughter processes such as handling, stunning, and bleeding (Carrascal et al, 2021). To promote the design of training programs and the implementation of good practices to improve human-animal relationships in the slaughterhouse, it is necessary to investigate how workers perceive pigs during pre-slaughter operations.…”
