An IUL Countermat automatic colony counter was used to enumerate colonies on spiral total viable count plates made with a wide variety of foods. The counter results exhibited a correlation with manual counting results similar to the reproducibility obtained with manually counted spiral plates. Use of this machine results in a large time saving compared with the conventional counting method and is recommended as a generally suitable method for counting spiral total viable count plates.
