A total of 96 bovines originating from 36 farms and 97 pigs from five farms were slaughtered in two multispecies abattoirs and subjected to official meat inspection and haptoglobin (Hp) testing using a single radial immunodiffusion method. No direct correlation between Hp level and specific postmortem abnormalities was found at individual cattle/pig level. However, at animal group level, the mean of Hp values (in both cattle and pigs) were statistically significantly higher in animals with abnormalities than in those without. The study indicated that the mean Hp value in groups of cattle or pigs can be useful as an overall objective indicator of the overall status of cattle/pig batches when analyzing the food chain information as a part of the antemortem inspection at abattoirs, but related specific Hp criteria are currently missing. Because of the large variability and nonspecific nature of Hp-related responses in cattle and pigs, establishing a single, reliable cutoff Hp value differentiating batches that may pose public health risks does not appear as a realistic approach presently. Rather, establishing wider, unsatisfactory/marginal/satisfactory ranges of batch-based Hp values indicating general appropriateness of the cattle/pigs source appears more promising. For that, wider Hp baseline studies are necessary at abattoir.
共有 96 头源自 36 个农场的牛和 97 头来自 5 个农场的猪在两个多物种屠宰场被屠宰,并使用单一的放射免疫扩散法进行了官方肉品检验和触珠蛋白 (Hp) 检测。在个体牛/猪水平上,未发现 Hp 水平与特定死后异常之间存在直接相关性。然而,在动物群体水平上,有异常的动物的 Hp 值(牛和猪)平均值在统计学上显著高于无异常的动物。该研究表明,当作为屠宰场宰前检查的一部分分析食物链信息时,牛或猪群体的平均 Hp 值可作为牛/猪批次整体状况的总体客观指标,但目前缺少相关的特定 Hp 标准。由于牛和猪的 Hp 相关反应具有很大的可变性和非特异性,因此目前看来,建立一个能够区分可能对公共健康构成风险的批次的单一、可靠的 Hp 截止值并不现实。相反,建立更广泛的、不满意/边缘/满意的基于批次的 Hp 值范围,表明牛/猪来源的一般适宜性似乎更有希望。为此,屠宰场需要进行更广泛的 Hp 基线研究。
