The following reminders should help in avoiding the common pitfalls encountered during enumeration of microorganisms in food:

 Notice the difference in usage of “colony count” and “population count.”

 When a specific microbial population is counted, the generic word “population” is replaced with a word or a phrase that describes the population. For example, in subsequent chapters, the “population count” is reported as aerobic mesophilic count, spore count, Enterobacteriaceae count, etc.

 Population count should be presented in scientific notation, with two significant digits only reported (e.g., 3.7×108).

 In all examples presented, population count was based on unit food weight (g); however, samples of many liquid foods are measured volumetrically. In the latter case, population count is more accurately represented as CFU/ml.
