Brown- and white-shell chicken hatching eggs were given formaldehyde (HCHO) preincubation fumigation for 20 minutes with the recommended concentration of 1.2 ml of formalin added to 0.6 g of potassium permanganate per cu ft, and fumigant levels up to 5 times this amount. All fumigant levels destroyed the bacteria on the egg surface almost equally. Incubation for 48 hours at 37 C indicated as many as 99.85% of the bacteria killed on fumigated eggs. More bacteria were killed on brown-shell than on white-shell eggs. These findings confirm the efficacy of early on-the-farm preincubation fumigation of hatching eggs as a routine practice in a sound egg sanitation program.
