Ozone and formaldehyde were compared as poultry hatchery disinfectants in a poultry setter, and evaluated for effectiveness. Escherichia coli, Pseudomonas fluorescens, Salmonella typhimurium, and Proteus spp. were inoculated onto open petri plates and exposed to ozone or onto filter paper strips and exposed to ozone or formaldehyde in a poultry setter. Ozone (1.41 to 1.68% by weight) resulted in significant bacterial reductions of greater than 4 log10 on the open plates and greater than 3 log10 on filter paper strips, whereas formaldehyde (triple strength) resulted in greater than 7 log10 reduction on filter paper strips. Ozone was similarly lethal to organisms on filter paper strips at 90% relative humidity (RH) and 13.9 C, and at 50% RH and 37.7 C. Although under the conditions of this study formaldehyde (triple strength) was more lethal than ozone, ozone killed greater than 99.9% of the starting microbial populations. In the event that formaldehyde can no longer be used in the hatchery, an effective alternative may be ozone.
在育雏器中比较了臭氧和甲醛作为家禽孵化场消毒剂的效果。将大肠杆菌、荧光假单胞菌、鼠伤寒沙门氏菌和变形杆菌属接种到开放式培养皿上并暴露于臭氧中，或将其接种到滤纸条上并在育雏器中暴露于臭氧或甲醛中。臭氧（重量百分比为1.41%至1.68%）使开放式培养皿上的细菌显著减少超过4个对数10，滤纸条上超过3个对数10，而甲醛（三倍浓度）使滤纸条上的细菌减少超过7个对数10。在相对湿度90%（RH）和13.9℃以及50%RH和37.7℃条件下，臭氧对滤纸条上的微生物同样具有致死性。尽管在本研究条件下甲醛（三倍浓度）比臭氧更具致死性，但臭氧杀死了超过99.9%的初始微生物种群。如果孵化场不再能使用甲醛，臭氧可能是一种有效的替代品。
