The European Food Safety Authority (EFSA) identified extended-spectrum β-lactamase/AmpC β-lactamase (ESBL/AmpC)-producing as one of the main priority hazards for poultry. Different studies detected ESBL-producing at broiler fattening farms and in abattoirs, concluding that poultry meat is a potential source of human infection. Broiler breast skin samples taken in three abattoirs with different scalding techniques were examined for ESBL-producing (.) and their phylogenetic groups. A total of 307 ESBL-producing isolates were found, and the abattoir with conventional immersion scalding with thermal treatment of the water had the lowest incidence. Phylogroups D/E and B1 were mostly detected, while phylogroups C, D, and E were not detected. Phylogroup B2 was detected in low proportions. The phylogroups B2 and D are important as they have been associated with urinary tract infections in humans, but were only detected in low proportions at different processing stages in this study. Since the risk for the consumer of being infected via chicken meat with ESBL-producing and of highly pathogenic phylogroups cannot be excluded, good kitchen hygiene is of great importance.
欧洲食品安全局（EFSA）将产超广谱β-内酰胺酶/ AmpCβ-内酰胺酶（ESBL / AmpC）确定为家禽的主要优先危害之一。不同研究在肉鸡育肥场和屠宰场检测到产ESBL菌，得出禽肉是人类感染潜在来源的结论。对采用不同烫毛技术的三个屠宰场采集的肉鸡胸部皮肤样本进行了产ESBL菌（.）及其系统发育群的检测。共发现307株产ESBL菌分离株，采用水热处理的传统浸泡烫毛的屠宰场发病率最低。主要检测到系统发育群D / E和B1，而未检测到系统发育群C、D和E。系统发育群B2的检测比例较低。系统发育群B2和D很重要，因为它们与人类尿路感染有关，但在本研究的不同加工阶段仅检测到较低比例。由于不能排除消费者通过鸡肉感染产ESBL菌和高致病性系统发育群菌的风险，良好的厨房卫生至关重要。
