Write a one to two page summary of the following learning objectives:

Understand:

1. coliforms are indicators of fecal contamination and that most foodborne illness pathogens have fecal reservoirs
2. the history of cholera and how it led to the need for sanitary water monitoring (why couldn't we just look for V. cholera?)
3. the risk of cholera today in US versus third world countries (not in materials - look it up)
4. the differences in coliform, fecal coliform, and E. coli
5. how galactosidase detects coliforms and glucuronidase detects most E. coli strains
6. how Salmonella, Shigella, E. coli O157, and Enterobacter fit into the coliform, fecal coliform, E. coli indicator assay
7. both the MPN and membrane filtration techniques for determining coliforms in samples
8. how petrifilm products work to enumerate coliforms and E. coli
9. coliform indicators are far from perfect and they have their deficiencies
