For total viable count testing in the food and drink Industries, Merck provides an important assortment of high quality dehydrated culture media. TVC covers all germs in a food item when samples are cultured under optimal conditions. As one of the evaluations conducted to guarantee customer safety, total viable count is used as a quality indicator in the food and beverages industries. It can be used for measuring the sterile quality of a product, the efficacy of processes like heat treatment, the status of raw materials, and the sterile condition of equipment. The high quality, consistent press that Merck supplies for the Enrichment, isolation and enumeration of indicator organisms are offered in many different formulations as dehydrated culture media in the form of granules.
Merck’s uniquely granulated culture media aren’t only convenient but also safe, meeting the highest industry performance criteria as described in ISO 11133. Granulated media cause considerably less dust than powdered media when used in the laboratory. Dust reduction contributes to less inhalation of poisonous media components that might lead to allergic responses. Additionally, it reduces contamination of the work environment bioburden testing. All Merck websites are quality controlled based on strict standards. This ensures that the consistent high quality of our microbiology products.
Test substance spiked at low levels with agent organisms including the aerobic bacterium Staphylococcus aureus, spore forming bacterium Bacillus subtilis, anaerobic bacterium Clostridium sporogeneses or the fungus Candida albicans are utilised to ensure there isn’t any inhibitory effect from the sample that may mask contaminants, to be able to validate the evaluation. The rationale behind incubating potable water samples at 22 and 37˚C respectively would be to delineate between what may be considered environmental contamination and microbiological contaminants of human significance, as we realize that the optimal growth temperature for waterborne pathogens such as Legionella pneumophila is 37˚C.
