The efficacy of chlorine dioxide (ClO2) as an alternative sanitizing agent for hatching eggs was investigated because of the health concerns about formaldehyde fumigation. Hatchability of chicken eggs was reduced when the eggs were dipped in the ClO2 solutions for more than 5 minutes or in concentrations greater than 100 ppm Cl. However, treating hatching eggs with a ClO2 foam or fumigating with formaldehyde had no adverse effect on hatchability compared with untreated control eggs. Sanitizing soiled duck eggs with ClO2 foam improved hatchability by more than 10% and hatch by more than 6% compared with untreated eggs (P less than 0.05). A novel method for assessing bactericidal potential of egg-sanitizing agents was developed. Using this technique, both chlorine dioxide foam and formaldehyde fumigation reduced the number of egg-contaminant bacteria inoculated on sterile chicken eggs compared with the number of bacteria on untreated eggs (P less than 0.05). These findings suggest that sanitizing hatching eggs with ClO2 foam may be a viable alternative to fumigating with formaldehyde.
由于对甲醛熏蒸存在健康担忧，因此对二氧化氯（ClO2）作为孵化蛋替代消毒剂的效果进行了研究。当鸡蛋在ClO2溶液中浸泡超过5分钟或浓度高于100 ppm Cl时，鸡蛋的孵化率会降低。然而，与未处理的对照蛋相比，用ClO2泡沫处理孵化蛋或用甲醛熏蒸对孵化率没有不利影响。与未处理的蛋相比，用ClO2泡沫对脏污的鸭蛋进行消毒可使孵化率提高超过10%，孵化数提高超过6%（P小于0.05）。开发了一种评估蛋消毒剂杀菌潜力的新方法。使用该技术，与未处理蛋上的细菌数量相比，二氧化氯泡沫和甲醛熏蒸均减少了接种在无菌鸡蛋上的蛋污染细菌数量（P小于0.05）。这些发现表明，用ClO2泡沫对孵化蛋进行消毒可能是甲醛熏蒸的可行替代方法。
