Methodology
Using a quantitative approach, we surveyed personnel at meat plants
in Ontario and obtained 124 useable surveys.
Survey instrument
•Based on a qualitative study and literature (Wilcock, 2010)
•65 scale items as well as demographic questions
•Scale items related to five areas:
–management commitment to food safety (including
leadership and resource allocation)
–work unit commitment to food safety (including supervisor,
co-worker and personal commitment)
–food safety training
–infrastructure for food safety (including food safety
management system, food safety personnel and production
practices)
–worker food safety behavior
•Response options for scale items based on a 7-point Likert scale
anchored at
–strongly disagree (1) and strongly agree (7) for 58 items
–never (1) and always (7) for the remaining 7 items regarding
personnel behavior
•Face validity assessed by experts in the field
Survey administration
•Self administered by
–all personnel at small plants
–all salaried personnel and hourly quality assurance/food
safety personnel at medium//large plants
Participating firms
•Five further-processing establishments
Data analysis
•124 useable questionnaires after standard procedures for data
screening
•Factor and reliability analyses conducted using SPSS 17
–Principal axis factoring using direct oblimin rotation on the
correlation matrix; missing value cases excluded pairwise
–Four scale items removed due to low communalities as
recommended by Costello and Osborne (2005)
– Cronbach’s alpha reliability analysis on all 15 factors; scale
items removed to improve αas needed
Results and Discussion
Fifteen factors with Eigenvalues of greater than 1 were extracted. One factor had a considerably higher Eigenvalue (22.214) than the
others (3.386-1.062). As was expected, the analysis matricies showed considerable cross loading. Most items loaded at >.400 on two
or more factors, suggesting the potential for higher order factors (i.e., factors that contain several subfactors) (Table 1). Tests of
sampling adequacy were acceptable (Kaiser-Meyer-Olkin = .665; Bartlett’s test of sphericity (homogeneity of variances)
χ2 = 5502.609 (1830) , ρ< .001). Fifty-one of the scale items remained after the reliability analysis on the fifteen extracted factors;
Cronbach’s alpha scores for the constructs ranged from .668 to .922.
Work unit commitment to food safety as a higher order factor contained elements of worker commitment to food safety as well as
supervisor commitment to food safety (through positive and negative actions) and supportive communication. Personal understanding
of food safety (roles and knowledge about tasks) was distinct from work unit commitment and behavior, although this may be due to
this factor being answered by personnel at various levels. Management commitment items cross loaded with more factors than other
items and showed several distinct subfactors. Food safety system support items also cross loaded, suggesting this factor may influence
or be influenced by other factors.
The development of valid measurement items provides the necessary tools required to research food safety culture. This tool will
enable the quantitative investigation of key factors that contribute to food safety behavior. This supports the concept of food safety
climate, an aspect of food safety culture.
Introduction
What is ―food safety culture‖? How can you measure it?
There is little quantitative evidence to support the claim that there is a
definable ―culture‖ that contributes to appropriate behavior of
workers in food plants. Climate, often considered a snapshot of
culture, is a useful proxy. Health and safety literature contains
validated scales for safety culture and climate; there are no
comparable scales to assess food safety culture or climate.
Yiannas (2009) describes various attributes of a food safety culture,
including strong leadership and commitment to food safety
throughout the organization.
Popular thought is that management commitment determines worker
food safety behaviour (Ball et al. 2009). Training has been shown to
be an important element—ensuring that workers know what they
ought to do—yet it does not necessarily translate into practice
(Griffith 2010). Ball et al. (2010) identified that work unit factors and
food safety system requirements also contribute to desired behavior.
The objective of this study was to validate a measurement tool for
identifying key factors that influence meat plant workers to follow
food safety behaviors in their plants.
