Abstract
Slaughtered animals are regularly submitted to post-mortem inspection to ensure that all the edible parts are fit for human consumption. According to Regulation (EU) No 219/2014, pig carcasses inspection is exclusively visual as palpation and incision could lead to cross-contamination and spread of relevant zoonotic agents. However, when compared to incision and palpation, the visual method is characterized by low sensitivity; thus, the omission of incision and palpation could lead to a reduced detection capability of organic lesions. This study aims to assess the effectiveness of exclusively visual inspection to mark pulmonary and hepatic lesions associated with low public health impact diseases in pork carcasses. A quasiexperimental- before/after research protocol has been used. All the post-mortem inspections have been carried out in a slaughterhouse located in the province of Teramo (IT), on 7,764 swine from 2011 to 2017. Carcasses undergone the only visual inspection have shown a statistically significant reduction (pvalue <0.0001) in the diagnosis of hepatic (decrease of 59%) and pulmonary diseases (decrease of 38. 5%). To overcome the limits of the low sensitivity of the visual inspection, as well as the inter-operator diagnostic variability, the high number of carcasses examined is proposed as a factor conferring external validity to the study, which provides quantitative evidence in support of the causal association between the modified inspection technique and the reduced diagnostic capacity. A further support derives from the assessment of the prevalence of hepatic and pulmonary diseases in species for whom the inspection technique is not changed.
屠宰的动物会定期接受宰后检查,以确保所有可食用的部分适合供人食用。根据法规(EU) No 219/2014,猪尸体检查完全是目视检查,因为触诊和切口可能导致交叉污染和相关人畜共患病病原体的传播。然而,与切口和触诊相比,目视法的特点是灵敏度低;因此,省略切口和触诊可能导致对器质性病变的检测能力降低。本研究旨在评估对猪肉胴体中与低公共卫生影响疾病相关的肺和肝病变进行单独目视检查的有效性。采用了准实验前/后研究方案。2011年至2017年期间,在特拉莫省的一个屠宰场对7764头猪进行了所有死后检查。经过唯一的目视检查的尸体显示统计学上显著的减少(p值)
