could have a total coliform count (total count on Macconkey) up to
104 CFU/ g, and they will still be considered acceptable for
consumption, above this number they will be unacceptable. A cheese
brand was doubted to be the cause of food poisoning, a sample of
the cheese was tested in the lab. Results are summarized in table
below.
