Caracterização da microbiota de leite cru comercializado em Alagoas e sua relação com a climatologia da região do Semiárido alagoano

Abstract

Agricultural production in Brazil plays reputed role in setting the national economy and its economic activities directed to the livestock led the population of the countryside and the informal marketing of raw milk is a common problem. The semiarid northeast composes the main dairy regions of Brazil, whose production is mainly coming from small farms family-based, unquestionable socioeconomic relevance. The product of this acquisition system is still practiced under precarious sanitary conditions, which leads to higher counts of microorganisms, which may constitute a risk to public health, especially when consumed without adequate heat treatment. Studies indicators and pathogenic microorganisms in food are important for being a source of concern to cause Transmitted Disease outbreaks for Food (DTA). Several elements interfere with the production and quality of raw milk, including with regard to the animal health and biometeorological factors are intrinsically linked to dairy cattle. The study aimed to characterize the microbiota of raw milk sold in regions of the State of Alagoas and its relationship with the weather influence in 07 regions of Alagoas semiarid region as the determination of coliforms at 45 ° C, Escherichia coli research; and coagulase-positive Stapphylococcus count of Listeria monocytogenes and research. Microbiological data showed considerable Coliform count at 45 ° C, E. coli and Staphylococcus coagulase positive for samples of raw milk of Alagoas semiarid region, depending on the time of year and climate transition periods, not detected Listeria monocytogenes in any sample, despite the possible occurrence milking environments.
