	%X Polymerase chain reaction (PCR) assay and
conventional microbiological methods were used to detect bacterial
contamination of egg shells and egg content in different commercial
housing systems, open house system and evaporative cooling system.
A PCR assay was developed for direct detection using a set of
primers specific for the invasion by A gene (invA) of Salmonella spp.
PCR detected the presence of Salmonella in 2 samples of shell egg
from the evaporative cooling system, while conventional cultural
methods detected no Salmonella from the same samples.
