Prevalence of Clostridium perfringens in commercial broiler hatcheries

Clostridium perfringens, a cause of human foodborne and poultry disease, has been isolated front the intestinal tract Of poultry and from the processed carcass. Little is known about the incidence and sources of this pathogen in the poultry production environment. To determine if the broiler hatchery is a possible Source of C. perfringens, we collected samples from three hatcheries, each operated by a different poultry integrator, and the presence of C perfringens in these samples was determined. For each sampling period, eggshell fragments, chick fluff from the hatcher, and paper pads stored in the hatchery before use with chicks and after placement beneath chicks fur I hr were evaluated. Clostridium perfringens was found in eggshell fragments, fluff, and paper pads in each of the three hatcheries. The percentages of C perfringens-positive samples from the three hatcheries ranged from 13% to 23%, with. an overall incidence of 20%. positive samples were consistently found, i.e., detected on each of die nine sampling days (three sampling days for each of three hatcheries). These results suggest that the hatchery is a potential source/reservoir for C perfringens in the integrated poultry operation.
