Efficacy of a novel foot pan in biosecurity protocols for control of salmonellae in poultry farms

This study aimed to replace liquid foot pan in the poultry farm, with a novel modelthat is used more effectively in biosecurity program convenient with the workersin Egyptian farms that avoid foot pan. This novel model dry foot pan, semiliquid(wet) foot pan and floor mat that enabled the disinfectants to be worked for alonger time. In the present study authors are looking for a durable footbath,stable, fast, easily applied and log acting in the reduction of salmonellae. Theefficacy of powder disinfectant (calcium hypochlorite powder, Halamid, Staldren,Virkon S and paraformaldehyde) were tested against salmonellae in a novel formof foot pan dry, semi-liquid and floor mat models. The disinfectants were dilutedby calcium carbonate or sodium chloride powder in the dry form, surfactant in thesemiliquid form and use of the sponge as a mat in the third form. Dailymeasurement of the active principle of the tested disinfectants and the logreduction of the Salmonellae were done. The dry form and semi liquid form of theCalcium hypochlorite was successfully effective for 10 days in dry form and 9 daysin semiliquid form. However, Halamid and Staldren were successfully effective indry form for 14 days and 17 days respectively, semiliquid form was worked for 21day and 3 days and floor mat was effective for 21 days and 3 days respectively.Paraformaldehyde powder was also effective for 6 days in the dry form, but in thesemiliquid form was effective for 10 days, floor mat was effective for 12 days. 5%Virkon S could be effective for 3 days in the dry form and semi-liquid form but only2 days in the floor mat form.
