ABSTRACT Milk and dairy products are potential sources for spoilage and pathogenic microorganisms, and although a huge amount of data is collected by the official inspection services, only a few reports are available to the public. This study aimed to evaluate the data for physicochemical and microbiological quality of pasteurized milk and dairy products, collected for inspection at industrial establishments registered at the Instituto Mineiro de Agropecuária (IMA), which is an official inspection service in Minas Gerasi State, Brazil. A total of 192 analyzes were done in 2011, 1008 in 2012, 1368 in 2013, 1271 in 2014, 1582 in 2015, adding up to 5421 samples analyzed by standard analytical techniques in official government laboratories. The statistical analysis was descriptive. A total of 2010 analytical results were nonconform to the legal requirements. Among the results, 78 (4.3%) samples of mozzarella cheese were positive for alkaline phosphatase, and freezing point results for pasteurized milk were outside the legal requirements in 86 (10%) samples. Staphylococcus coagulase positive was above limits in 80 (4.4%) samples of mozzarella cheese. These results indicate a risk to the consumer’s health even in pasteurized products, and the need for effective enforcement of good manufacturing practices in the food industries.
