DETECTION OF BILE DUCTS PATHOLOGIES IN BOVINE LIVERS AND ITS IMPACT ON VETERINARY INSPECTION IN SLAUGHTERHOUSES
Abstract
The bovine liver is one of the main viscera from cattle delivered for human consumption. It must be controlled based on sanitary standards to be a safe product. In Spain, these standards are stipulated by the Regulation (EU) 2019/627, where the modalities of veterinary inspection are only visual, unless the official veterinarian considers palpation and incision necessary. When applying a visual inspection, it is possible that some pathologies, such as those of the bile ducts, might not always be seen on the liver surface, so they could not be detected. This study aims to show if the current official controls in cattle slaughterhouses lead to a reduction in the detection of pathologies that affect the bile ducts. To accomplish this goal, in a Spanish abattoir, from a 300 bovines population, all the livers that the official veterinarians considered suitable for human consumption were incised, to observe if they showed any pathology in the bile ducts not visually detected by them. With the collected data, a descriptive observational study was carried out, where the frequencies and prevalence of the pathologies before and after the incision were calculated. We obtained that the official veterinarians declared 16 livers not suitable for human consumption due to apostematous hepatitis, fascioliasis, peritonitis, stasis and dicrocoeliasis. Consequently, they gave 284 livers as suitable for human consumption. Later, due to the incision, it was detected that three of them had dicrocoeliasis, resulting in an increase in its prevalence of 1,33% to 2.33%. Hence, it can be concluded that the omission of incisions in the liver inspection because of the application of the current regulations on the official controls, implies a decrease in the detection of pathologies in the bile ducts such as dicrocoeliasis, they might end up for human consumption.
