Abstract
Salmonellae can penetrate egg shells without causing decomposition of the egg. As these chicks hatch, reservoirs of salmonellae can take hol d on the commercial hatchery. Our study in 1990 sampled eggshells from hatching trays, belt swabs, and paper pads from three commercial hatc heries and found that 75.5%, 90.9% and 66.7% contamination, respective ly. This study in 1995 repeated these samples, but found 22.5%, 52.2%, and 12.1% contamination, respectively. The decline in salmonellae con tamination is both dramatic and encouraging, resulting from several im portant factors.
