Abstract / Zusammenfassung

Background:
Bacterial contamination in poultry products is of major concern for the poultry industry and consumers. The present study focusses on the reduction of bacteria on eggshells at the beginning of the broiler production chain. Four disinfection methods were selected for this field study, based on previous in vitro and in vivo data from laboratory disinfection trials against ESBL (extended-spectrum beta-lactamase) producing E. coli.

Objectives:
Four different disinfection methods were tested in a field trial for a) their efficacy on the eggshell and effects on b) hatching rate, c) meconium microbiota and d) performance.

Methods:
Five groups were tested 1) Formalin fumigation, 2) H2O2 + alcohol, 3) peracetic acid and 4) low energy electron beam, 5) non-disinfected control group. Each contained 2 000 - 54 000 eggs, depending on the complexity of the disinfection. Eggs were incubated, chicks hatched and were housed separately under normal field conditions. a) Disinfection efficacy was determined using egg wash samples comparing non-treated and disinfected groups. b) The hatching rate was analyzed for all groups. c) Meconium pool samples of newly hatched chicks were collected separately for all groups. d) The flock performance was compared with respect to i.e. weight gain. All samples were examined for total bacterial count, ESBL producers and MRSA.

Results:
Formalin fumigation, peracetic acid and low energy electron beam reached a 2-fold log reduction (and more) in total bacterial counts. The hatching rate was comparable. Detailed results on meconium composition of hatched broiler chicks will be presented along with performance data.
