The effects of washing with kitchen soap on the interior qualities of fertile and infertile chicken eggs during the storage were studied. Egg were divided into 4 groups, (1) None washing fertile eggs. (2) None washing infertile eggs. (3) Washing fertile eggs. (4) Washing infertile eggs. All eggs were kept at room temperature (about 25.degree. C) for 0, 1, 3, 5, 7, 9, 11 and 15 days and were broken for the measurements of interior qualities of eggs. Albumen height and Haugh unit of fertile and infertile egg were significant decreased by washing as the storage days advanced. However, there was no effect of washing on the egg weight loss, yolk diameter and yolk index during the storage.
