From page 528... ...
Most human health risk assessments have been conducted on carcinogens. Such risk assessments are based on chronic, lifetime exposure to a particular agent and almost always rely on evidence obtained from animal tests (such as rats or mice)

, although there are differing actions taken under different federal statutes (Rosenthal et al., 1992~. With infectious microorganisms, for which uniform guidelines do not exist, the process of risk assessment may be conducted in a similar manner (Haas et al., in press)

From page 530... ...
Risk assessment may be particularly beneficial in conjunction with an epidemiological surveillance program. If the dose-response curve is extrapolated to low levels of risk, it is possible to ascertain the level of infection implied by a particularly low level of exposure.

to define levels of contamination where particular public health actions must be taken. Limitations on method efficiency and rapidity may, however, limit the present ability to use microbial risk assessment in such a real-time manner.
