of molten, cooled, and nonselective agar (for exampleYeast Extract Agar) in a
petri dish. The agar is allowed to set then incubated at the desired temperature
and duration. Following incubation, bacterial and fungal colonies will grow
within the agar and can be counted and reported as cfu mL −1 ( Fig. 3.3 ). 12
The main focus of this topic is based upon the description, review and
evaluation of emerging methods of detection, as covered in Chapters 5-10.
However, the field of fecal indicator monitoring is also developing, with the
identification of new indicator organisms, offering improved correlation
with groups of pathogens 13 or the design of new technology. Many different
