Limitations of the research stem from the use of a convenience
sample. People interpret numbers and scales differently, but for
data analysis, it was assumed that respondents have the same
understanding of numbers and scales as the researchers. Since the
data were collected in three cities, the current result should not be
generalized. Given the great cultural and other differences within
the three cities, more research is necessary to determine if similar
results would be derived across various other continental and
Mediterranean European cities. This study did not attempt to
specify hypothesis regarding food hygiene profile of an average
European food establishment.
