Avaliação da Qualidade Microbiológica de Leite Cru comercializado no Município de Trindade, GO

Abstract

This study aimed to evaluate the microbiological contamination of raw milk sold in the city of Trindade, located in the metropolitan area of the state capital of Goiás, Brazil. For this, ten points were chosen representative of the city to perform the collection of samples, which were collected for two consecutive days and times of delivery of milk in residence. For collecting the samples were measured instantaneously with respect to temperature, to evaluate these indices according to the parameters of IN-51/MAPA. As for pH samples were 100% above standard temperature and 90% samples with pH value below the value defined by normative instruction. Through microbiological analysis could detect up to 65% of the samples were contaminated with Mesophiles and 35% contaminated with total coliforms and 35% Stapylococcus coagulase positive. The detection of E. coli in two collection points illustrates the failure of the health authority to monitor compliance of IN-51 and importance of an education program to raise awareness of the need to establish hygienic conditions in all processes from production to consumption of milk.
