Resumo
The objective of this study was to verify the physical, chemical and microbiological quality of
Japanese quail eggs artificially contaminated with Salmonella enterica ser. Typhimurium. The eggs
were sanitized and stored at different temperatures (between 5 and 25 ºC) for 27 days. We used 768
eggs with opaque shells, typical pigments of the species, and average weight of 11 g. The experimental
design was completely randomized in a 2x2x2 factorial arrangement (contamination x sanitation x
cooling) with six replications and one egg per experimental unit. The eggs were contaminated by
handling with 1.5 x 105 colony forming unit (CFU) of Salmonella. Typhimurium / mL and sanitized
according to the treatments with a 5 ppm Cl solution. The data were subjected to analysis of variance
and t test. Bacterial contamination has damaged the egg weight, Haugh unit, yolk index and albumen, and pH of yolk and albumen, from 18 days of storage. The egg storage time and storage temperature
affected the internal quality of quail eggs in all variables. The worst internal quality was observed in
eggs stored at 25 ºC. The sanitation and cooling reduced the growth of Salmonella in contaminated
eggs. Eggs in opaque shell, when not refrigerated, should be consumed within 18 days after laying.
