Results
Background
Raw meat and poultry are potentially
hazardous commonly handled and cooked
foods in restaurants.
In a knowledge survey of 508 restaurant food
handlers performed in Chicago restaurants in
2009, the overall mean knowledge score was
only 72%.
However, this knowledge score may be
underestimated because the survey included
some questions that may not be relevant to
each food handler’s specific duties.
We analyzed knowledge data concerning
meat and poultry food handling only among
the subset of food handlers that work with
meat and poultry.

Methods
We analyzed data derived from a 41question survey of 508 food handlers from
125 participating restaurants in Chicago.
Only the 372 meat and poultry handlers
were included in the analysis.
The survey had true-false or multiplechoice format (incorrect responses or ”do
not know” were assigned to 0) and
included 13 questions specific to meat or
poultry handling or cooking processes
(Figure 1). Only these 13 meat and poultryspecific knowledge questions were
analyzed to determine the knowledge
score. For comparison, these 372 food
handlers scored 72% overall on the general
knowledge survey.
The percentage of incorrect responses
among meat and poultry handlers was
compared and the frequency distributions
of meat and poultry specific knowledge
questions was determined.

Restaurant Characteristics of the Food Handlers
The objective of this study was to determine
if the knowledge score of food handlers
would be much higher than previously
recorded if the score was based only on
questions relevant to their food handling
duties.
Even though we limited the subanalysis to
meat and poultry handlers responses to meat
and poultry-specific questions (and 66% of
them surveyed were certified), the mean
knowledge score (72%) was not substantially
higher than the mean score using a more
general food safety knowledge survey (72%).

Food safety certification should require a
higher level of knowledge to be considered
certified or more frequent verification that
knowledge is retained with an emphasis on
knowledge of proper storage, cooking
temperatures, severity of illness, and
prevention of cross contamination.

Overall mean score= 77% (10 correct/13 questions)
Standard deviation= 13.8%
12.2
Range= 38%-100%
More than 1/3 of these food handlers did not
know about the severity of illness that may
result from eating incompletely cooked beef.
This raises the concern that they may not
appreciate the rationale for the
recommendations for checking temperatures
in a menu item such as meatloaf.
