： In countries with intensive pig husbandry in stables, the prevalence of livestock-associated (LA) methicillin-resistant (MRSA) on such farms has remained high in the last few years or has also further increased. Simple measures to reduce the LA-MRSA among pigs have not yet been successfully implemented. Earlier publications showed a decontamination of LA-MRSA was only possible with great effort. The aim of this study is to determine the suitability of routine cleaning and disinfection (C&D) for adequate LA-MRSA decontamination. For this purpose, at least 115 locations in a piglet-rearing compartment were examined before and after cleaning and disinfection. The sample locations were stratified according to accessibility for pigs and the difficulty of cleaning. The cleaning work was carried out routinely by farm employees, who were not informed about the sampling (single blinded). While before cleaning and disinfection, 85% of the samples from the surfaces were LA-MRSA positive, while only 2% were positive thereafter. All LA-MRSA-positive samples after cleaning and disinfection were outside the animal area. Air samples also showed no LA-MRSA after cleaning and disinfection. Conclusion: In well-managed livestock farms, decontamination of the LA-MRSA barn is quite possible; after C&D no LA-MRSA was detectable at animal height.
在集约化养猪的国家，过去几年中，此类农场中与牲畜相关的（LA）耐甲氧西林金黄色葡萄球菌（MRSA）的流行率一直居高不下，或还在进一步上升。降低猪群中LA-MRSA的简单措施尚未成功实施。早期的出版物表明，要对LA-MRSA进行去污非常困难。本研究的目的是确定常规清洁和消毒（C&D）对充分去除LA-MRSA的适用性。为此，在仔猪饲养栏中至少115个位置在清洁和消毒前后进行了检查。样本位置根据猪的可达性和清洁难度进行分层。清洁工作由农场员工按常规进行，他们未被告知采样情况（单盲）。清洁和消毒前，表面样本中85%为LA-MRSA阳性，而之后只有2%为阳性。清洁和消毒后所有LA-MRSA阳性样本均在动物区域之外。空气样本在清洁和消毒后也未显示LA-MRSA。结论：在管理良好的畜牧场，对LA-MRSA畜舍进行去污是完全可能的；清洁和消毒后，在动物高度未检测到LA-MRSA。
