estimate that, each year, between 6.5 and 33 million
people in the United States become ill from microbial
pathogens in their food; of these, up to 9,000 die (CAST,
1994). These figures are estimates based on reported
outbreaks and other epidemiologic data. The actual
number of reported cases is much smaller, averaging
about 18,000 cases of foodborne disease for the period
1983-87 (CAST, 1994). There are several reasons why
the range of estimated cases is so much greater than the
number of actual, reported cases. First, many foodborne
illnesses have symptoms that are similar to other gastro-
enteric illnesses, and might not be reported by physicians
as foodborne. Second, in some cases there is a delay of
days or weeks between exposure to a foodborne patho-
gen and the resultant illness; many illnesses that are
reported are not linked to specific foods or pathogens.
Finally, many people who become ill do not seek medical
care, and these cases are, therefore, not reported.

sources for seven pathogens for which we have the most
reliable information: These include
Salmonella, Campy-
