Análise microbiológica de águas do furo, cereais e seus derivados no Laboratório Nacional de Higiene de águas e alimentos, no período de Agosto à Dezembro de 2023

Abstract

Food safety is one of the main concerns currently faced by authorities, economic agents and consumers. Microbiological quality control is a legally required practice and is necessary to ensure that food safety management systems function correctly. Borehole water is one of the main sources of water for consumption at a national and global level, as well as the consumption of cereals and their derivatives, which are one of the main sources of nutrients. This report covers the internship that aimed at the microbiological analysis of borehole water, cereals and their derivatives from August to December 2023, in the Water and Food Microbiology sector of the National Laboratory of Water and Food Hygiene, a laboratory accredited by IPAC, according to NP EM ISO/IEC 17025. The internship allowed the development of a range of activities, such as quality control in the analysis of water for human consumption (with a greater focus on borehole water) where the target was the quantification of fecal coliforms, using the Membrane Filter method and of various foods (with a greater focus on cereals and their derivatives) which targeted the Determination of viable microorganisms at 37 °C, Coliform Count at 37 °C and 44 °C, Escherichia coli and Mold Count and Yeasts by the Incorporation method, the Counting of coagulase-positive Staphylococcus by the Spreading Seed method and the Research of Salmonella spp. These activities allowed the development of specific skills in quality control and implementation of standards and methods in the area of ​​food and water microbiology.(TRADUÇAO NOSSA)
