摘要: 冰箱冷藏室的微生物污染情况对用户的健康影响较大。为探究市售鲜鸡蛋沙门氏菌污染状况,及其冷储过程中对冰箱冷藏室污染状况的影响,对市售鲜鸡蛋进行沙门氏菌检测,将受污染的鲜鸡蛋放入冰箱冷藏室,设计对照实验检测冰箱冷藏室中的沙门氏菌。结果显示,该批次鲜鸡蛋中存在沙门氏菌,且受污染的鲜鸡蛋又对冰箱冷藏室造成了沙门氏菌污染。进一步对市售鲜鸡蛋及其冷储过程中残留于冰箱冷藏室的沙门氏菌进行测试,并对该沙门氏菌主要生化特征进行了分析。研究结果为后续冰箱研发设计提供了方向,为冰箱抗菌材料、除菌模块、相关工装的应用等提供了参考;同时也为家庭中冰箱的日常使用与维护提供了实践指导。

Abstract: The microbial contamination of the refrigerator freezer has a great impact on the health of users. In order to investigate the situation of salmonella contamination in commercial fresh eggs and the influence of cold storage on the contamination in refrigerator freezer, salmonella detection was carried out in commercial fresh eggs. The contaminated fresh eggs were put into the refrigerator freezer and a controlled experiment was designed to detect salmonella in the refrigerator freezer. The results showed that salmonella was present in the batch of fresh eggs, and the contaminated fresh eggs caused salmonella contamination in the refrigerator freezer. The main biochemical characteristics of Salmonella were analyzed. The research results a direction for the development and design of refrigerator, and provided reference for the application of antibacterial materials, sterilizing modules and related tools in refrigerator. At the same time, it also provides guidance for the daily use and maintenance of refrigerator in families.

Key words: Refrigerator, Refrigerate, Fresh eggs, Salmonella, Contaminate
