Effects of short-time disinfection on pathogenic bacteria,nutrients and immunoactive substances in shared breast milk in primary hospitals
OBJECTIVE To explore the effects of short-time disinfection on pathogenic bacteria,nutrients and im-munoactive substances in shared breast milk in primary hospitals.METHODS A total of 110 samples of breast milk that would be stored in the shared breast milk bank of Longyou County People's Hospitals in Zhejiang Prov-ince from Nov.2022 to Oct.2023 were selected as the study subjects.Bacterial detection,killing of standard strains,nutritional composition and immunoactive substances of breast milk before and after short-term disinfec-tion were compared.RESULTS Before short-term disinfection,bacteria were detected in 26(23.64％)out of 110 breast milk samples,and after short-term disinfection,bacteria were detected in 3(2.73％)out of 110 breast milk samples.The bacterial detection rate of breast milk after short-term disinfection was significantly lower than that before short-term disinfection(P＜0.05).The killing rate of standard strains of bacteria in sterile breast milk was more than 99.99％.There were no significant differences in the nutrient ratios of carbohydrate,fat,proteins and dry matter before and after short-term disinfection.There were no significant differences in the values of immuno-active substances such as IgG,IgM,sIg A,lysozyme and lactoferrin before and after short-term disinfection.CONCLUSION The short-term disinfection method used for breast milk disinfection in shared breast milk ware-houses of grassroots hospitals can significantly reduce the bacterial detection rate of breast milk,with a high bac-terial killing rate and minimal impact on the nutritional components and immunologically active substances in breast milk.
