To determine the source / load/ type of microorganisms in foods and water. The examination of raw ingredients also provide information about heat processing parameters that would be necessary to meet the microbiological standards. (2004) also investigated the quality of probiotic products licensed for medicinal purposes. In addition to tests for indicator organisms and certain specific pathogens, non-selective colony counts are also routinely carried out to determine the population of heterotrophic bacteria present. Question: Lab #21 : Microbiological Analysis of Food The microbiological analysis of food not only is necessary to insure the health of the food material but also as an aid to determining how sanitarily it was prepared. Microbiological tests As RTE foods include a wide range of products, the decision on what microbiological test to apply will depend on a number of factors: The total plate count is a good indicator for the overall bacterial load of meat and meat products. Over 35 years of microbiology experience. We can analyze meat and other food products to detect the presence of micro-organisms.
