Ozone and formaldehyde were evaluated as disinfectants in a prototype laboratory setter against microorganisms that are naturally present on fertile, freshly laid, broiler hatching eggs. Significantly lower microbial counts of over 2.5 log10 (P less than .05) were observed for water-misted and ozonated (2.83% by weight) eggs or formaldehyde-fumigated (triple strength) eggs than for control and water-misted eggs. Eggshell conductance studies as measured by egg moisture losses in a desiccator showed no significant differences (P greater than .05) among untreated, water misted, ozonated (3.06% by weight) with water mist, or formaldehyde (triple strength)-fumigated eggs. Hatchability was significantly reduced (26.5 to 37.5%) following ozonation (3.03% ozone by weight, 2 h) in comparison with effects of no treatment or water misting. Misting with ozonation was equally as effective as formaldehyde fumigation in reducing microbial counts. However, ozone treatment at the concentrations tested significantly reduced hatchability when compared with results of either no treatment, water misting, or an average hatchability figure for formaldehyde fumigation. These findings indicate that ozone is a good disinfectant yet may adversely affect embryo development when given in the gaseous form.
在一个原型实验室装置中，对臭氧和甲醛作为消毒剂针对新鲜产下的可孵化肉用种蛋上自然存在的微生物进行了评估。与对照蛋和喷水蛋相比，喷水并经臭氧处理（重量比为2.83%）的蛋或经甲醛熏蒸（三倍浓度）的蛋，微生物数量显著降低超过2.5个对数单位（P小于0.05）。通过干燥器中蛋的水分损失来测量蛋壳传导性的研究表明，未处理的蛋、喷水蛋、喷水并经臭氧处理（重量比为3.06%）的蛋或经甲醛（三倍浓度）熏蒸的蛋之间没有显著差异（P大于0.05）。与未处理或喷水处理的效果相比，臭氧处理（重量比为3.03%的臭氧，2小时）后孵化率显著降低（26.5%至37.5%）。喷水并进行臭氧处理在减少微生物数量方面与甲醛熏蒸效果相同。然而，与未处理、喷水处理或甲醛熏蒸的平均孵化率结果相比，在所测试浓度下的臭氧处理显著降低了孵化率。这些发现表明，臭氧是一种良好的消毒剂，但以气态形式使用时可能会对胚胎发育产生不利影响。
