Method Description


Samples are prepared and dilutions made. The samples are then plated on media and incubated based on method specifications. After incubation plates are read and results generated based on countable range.

Additional Information


Thermophilic spore forming bacteria grow in products held at elevated temperatures (55 C or higher), including during pasteurization, 62.8 C. When products are held at high temperatures for long periods, these types of bacteria rapidly increase in numbers which may cause flavors defects in the product.
 
These procedures enumerate the number of thermophilic aerobic (or anaerobic) bacterial spores present in a sample after heat shock.
