1.3 SimPlate Total Plate Count method SimPlate Total Plate Count Color Indicator (TPC-CI) method is used for the detection and quantification of total aerobic micro-organism populations. It is based on binary detection technology (BDT) which equates the presence of total aerobic micro-organisms to the presence of a colour change in the medium. The medium/sample mixture is dispensed into a The total plate count is a good indicator for the overall bacterial load of meat and meat products. Critical hygienic dimensions are reached when the total number of bacteria on fresh meat lays between 10,000 (1,0x10 4 ) and 100,000 (1,0x10 5 ) per g (see also page 353).

Standard Plate Count (SPC) By far the most widely used method for determining the number of viable colony forming units (CFU) in a food. Use a spread or pour plate (psychrotrophs may not survive as well in pour plates) that includes homogenized food sample. Total count is also termed as standard plate count or colony count. It gives the total number of microbes both viable and non-viable. All cells are counted. These include bacteria, yeasts and moulds. It is usually done by pour plate method. Total count generally requires employment of a microscope.

A multilaboratory study was conducted to determine the equivalence of the 3M Petrifilm Aerobic Count Plate and standard plating methodology for measuring viable bacteria and spores recovered from hard-surface carriers (stainless steel and porcelain), also known as "control carrier counts," used in AOAC antimicrobial efficacy test methods. The heterotrophic plate count procedure has been subjected to extensive changes to ensure the best possible recovery of heterotrophic organisms ( Reasoner,2004 ), resulting in variations in methods between countries

The total viable count is an important parameter in industrial fermentations. Traditional methods for total viable count started with the cultivation method of counting the colonies. Later methylene blue and Ponceau S stain came into use for microscopic examinations, which give a direct count … Use the Membrane Filtration method or one of the Plate-Count Methods, as directed. The Most-Probable-Number (MPN) Meth- od is generally the least accurate method for microbial counts; however, for certain product groups with very low bioburden, it

The eluent from the washing should be tested using an appropriate total viable count (TVC) test method, where membrane filtration is the method of choice, followed by the pour plate technique. The microbial counts from all washes are compared in order to assess the total bioburden. count capabilities has been to explore the possibility of looking at a frequency distribution models to establish control levels in these areas (9) or incident models (10).
