Determination of hygienic status of refrigerators surface

Abstract

This study was aimed to determine the microbial load and the hygienic status of household refrigerator surfaces. Psychrotrophic and coliform bacteria counts were carried out to determine the hygienic status of household refrigerators. Surface samples were investigated in 3 groups as housewives’, students’ and workers’ refrigerators, and each group, including ten refrigerators. A total of two hundred and forty samples, one hundred and twenty sides and one hundred and twenty shelves were taken from the side and shelf surfaces of a total of thirty different refrigerators. In general, when the results were examined, it was determined that the sanitation program and effectiveness of the workers’ refrigerators were sufficient, and the sanitation of the housewives’ and students’ should be examined or insufficient.

Keywords

• Refrigerator
