COLIFORMES E BACTÉRIAS MESÓFILAS EM OVOS DE CODORNAS COMERCIALIZADOS NAS CIDADES DE CERES E RIALMA - GO

Abstract

The objective was to evaluate the presence of coliforms and mesophilic bacteria in quail eggs sold in the cities of Ceres and Rialma - GO. Three different commercial brands were researched, with 8 repetitions of each brand, totaling 24 samples of quail eggs, carried out in a completely randomized design (CRD), purchased in supermarkets, with each sample being represented by different lots and formed by a “pool” containing 10 eggs, which were chosen randomly from cards with thirty units. The eggs were broken aseptically and the contents (glair + yolk) from the shell were separated. Microbiological analyzes were carried out to search for total coliforms, thermotolerants and mesophilic bacteria. For the determination of coliforms, the multiple tube technique was used and for the analysis of mesophilic bacteria, the surface plating technique was used. The results were expressed as Most Probable Number (MPN) and Colony Forming Unit (CFU). The samples analyzed were not positive for the development of total and thermotolerant coliforms, however, they were positive for the development of mesophilic bacteria. There was no statistical difference regarding the level of contamination by mesophilic bacteria between the brands analyzed, and all samples were in accordance with the current regulatory resolution.
