The egg is a product of animal origin (POA), is a food with high nutritional value, and low ec
onomic cost, being consumed mainly by the low-income population. Due to their nutritional
characteristics are one of the main products related to foodborne diseases (DTA) for humans.
As Birds are natural reservoirs of enteropathogens of public health importance, such as
Salmonella spp., contamination of eggs can occur enterically during laying or intra-ovarian.
Therefore, the egg can be a source of infection to humans when manipulated or consumed
improperly. The presente research aimed to compare the microbiological quality and safety of
Whole redneck eggs, commercialized in a clandestine manner, and poultry farms inspected in
Northern Tocantins, at the same time, comparing the recovery of isolates of this pathogen from
the peel and yolk to determine the origin of their contamination. Samples of the internal and
integral contente of the eggs were analyzed for the Count of mesophilic aerobic bactéria,
Staphylococcus spp., Most Probable Number (NMP/g) of total and thermotolerant coliforms,
and Salmonella and Listeria spp., research by conventional methods associated with
biomoleculars. Samples of eggshell and egg yolks were particularly evaluated for Salmonella
spp. research. The averages of aerobic mesophilics, Staphylococcus coagulase positive and
coliforms at 30o and 45oC among the redneck and inspected eggs were, respectively, 4,5 x 107
e 2,9 x 108
(p >0,05), 17 e 10 (p> 0,05). The recovery of Salmonella spp. from the peel and
yolk of redneck eggs was 63,6% (7/11) and 27,2% (3/11), while for the eggs inspected were
45.5% (5/11) and 27.2% (3/11). The inspected production of eggs on poultry farms, from
samples evaluated, predispose eggs to the lowest environmental/fecal contamination in relation
the eggs of redneck birds. It was also possible to observe the presence of Listeria spp.
contamination in a sample in farm eggs, potentially of origin of equipment and surfaces used
during processing, classification and ovoscopy. According to the research conducted, it was
concluded that the in natura eggs marketed in the northern region of Tocantins presented
deteriorating microorganisms and poor quality sanitary hygienic indicators. Salmonella
contamination may be linked to intra-ovarian and enteric infection. By determining the
microbiological hazards found in eggs, it is possible to establish strategies directed to the
control of production, as well as, intensify the surveillance programs of this pathogen to meet
the parameters of the legislation, both for the health of the squads and for the nurseries and for
the Sustainability of food safety.
