(range: 1-10) on the pre-test, whereas the majority of
students answered 9 or 10 questions correctly (range: 2-10)
on the post-test (Fig. 1).
Pre- and post-test scores for first-grade students were
significantly lower than scores for all other grades (P
< .05); mean post-test score for first grade was 64.1 ±
18.3%, versus 90.7 ± 11.3%, 85.2 ± 11.8%, 88.1 ± 12.6%,
and 90.6 ± 11.1% for second grade, third grade, fourth
grade, and fifth grade students, respectively. Scores for
students in grades two through five did not significantly
differ from each other. Analysis of covariance determined
that statistical significance was independent of the initial
knowledge score variations.
Pre- and post-test knowledge scores for each category
are illustrated in Figure 2. Correct baseline knowledge
was highest for container washing and lowest for produce
washing, 77.6% and 12.9%, respectively. The containerwashing category consisted of one question, whereas
the other three categories consisted of three questions.
Overall, knowledge within each category improved
significantly (P < .05) following the intervention.
of the students indicated that they liked the activities "very
much." Additionally, 84% (n = 161) of the students indicated
that they would tell their parents/guardians about what they
learned in the FSSGP (data not shown).
Parent/Guardian follow-up
A total of 59 (30%) parents/guardians returned the follow-up questionnaires to the teachers. Of the 59, 76% (n =
45) of the parents/guardians indicated their child spoke with
him/her about the FSSGP. Only two returned questionnaires
were not used because the topics mentioned were unrelated
to those taught in the FSSGP. Fourth- and fifth-grade students had the highest return rates, at 44% (16/36) and 55%
(10/18), respectively. First graders had the lowest return rate,
at 13% (8/63), and second and third graders returned 39%
and 36%, respectively.
Written responses were compiled and categorized into
five categories: bacteria, hand washing, produce washing,
animals, and other (Fig. 3). Any topic mentioned that
did not fall into one of the first four categories but was
related to food safety or gardening was included in the
"other" category. The "other" topics were grouped into
one category because of the low frequency and high
variability of each. Examples of topics in the "other"
category included any response about general food safety,
Program evaluation
The majority of the students rated each activity as okay or
better on the post-test evaluation (Table 5). More than half
