摘要

背景:所有类型的肠内喂养(EF)配方,无论是医院厨房的混合管喂养(BTF),还是商业肠内喂食(CEF),都含有营养物质。这些食物的性质(就pH值、营养成分、水分活度等而言)是这样的,如果它们被污染,会立即在里面滋生病原体,并使患者面临感染的风险。本系统综述旨在研究BTF和CEF在医院中的微生物安全性。方法:在Scopus、PubMed、Science Direct和Google Scholar等四个英文数据库中,使用肠内营养、混合配方奶粉、家庭肠外营养、肠内配方奶粉、EF、混合肠内配方、混合饲料、混合自制食品、CEF、微生物污染和细菌污染等多个关键词进行文献检索。最后,选择了16项符合条件的研究进行系统审查。结果:在132篇检索到的文章中,有16篇被选中并进行了审查。CEF主要暴露于总大肠菌群、金黄色葡萄球菌、中温菌和大肠杆菌的污染中。此外,还检测到革兰氏阴性菌、蜡样芽孢杆菌、霉菌和酵母的污染。大多数BTF污染是由总大肠菌群、嗜温菌、李斯特菌、蜡样芽孢杆菌、霉菌和酵母引起的。结论:由于不符合卫生指南,EF溶液在医院和家庭中的微生物安全性相对较低,可能导致食源性疾病。因此,危害分析和关键控制点(HACCP)系统在每个医院厨房中都是必不可少的。

Microbiological contamination of commercial enteral feeding and blenderized tube feeding: A systematic review
Background: All types of enteral feeding (EF) formulations, whether blenderized tube feeding (BTF) at hospital kitchen, or commercial enteral feeding (CEF), contains nutrients. The nature of these foods (in terms of pH, nutrient contents, water activity, etc.) is so that if they become contaminated, would immediately grow pathogens inside and put the patient at the risk of infection. This systematic review aimed to investigate the microbial safety of BTF and CEF used in hospitals. Methods: Literature search was conducted in four English databases, including Scopus, PubMed, Science Direct, and Google Scholar, using multiple keywords, such as enteral nutrition, blenderized formulas, home enteral nutrition, enteral formula, EF, blenderized enteral formula, blended feeds, blenderized home-made food, CEF, microbial contamination, and bacterial contamination. Finally, 16 eligible studies were selected for the systematic review. Results: Out of 132 retrieved articles, 16 were selected and reviewed CEF was mostly exposed to contamination with total coliforms, Staphylococcus aureus, mesophilic bacteria, and Escherichia coli. In addition, contamination with gram-negative bacteria, Bacillus cereus, mold, and yeast was detected. Most BTF contamination was caused by total coliforms, mesophilic bacteria, Listeria spp., B. cereus, mold, and yeast. Conclusion: Due to the nonconformity of hygienic guidelines, the microbial safety of EF solutions in hospitals and homes are relatively low, which may lead to foodborne diseases. Therefore, a hazard analysis and critical control point (HACCP) system is essential in every hospital kitchen.
