abstract
Food safety challenges are a global concern especially in emerging economies, which are in the midst of
developmental changes. The challenges are directly or indirectly related to the behaviour and decision-
making of personnel, and to an organisation's food safety culture. This study evaluated the prevailing
food safety culture in three Zimbabwean dairy companies of different size (multinational, large and
medium) using a comprehensive mixed-methods approach. Four key elements were assessed, namely
enabling conditions, employee characteristics, actual behaviour and microbial safety performance. Card-
aided interviews provided data on enabling conditions, and questionnaires and storytelling on employee
characteristics. Observations and microbial analysis assessed actual behaviour and microbial safety
performance, respectively. The multinational company demonstrated a more proactive food safety cul-
ture compared to the other companies, which operated at an active level as exhibited by multiple in-
consistencies in the enabling conditions and compliance behaviour. The large company had a moderate
microbial safety performance even though it operated in a potentially risky situation, which could have
been mitigated by the food safety management system. The medium-sized company had a poor mi-
crobial safety performance likely related to noncompliance with sanitation requirements, negative at-
titudes towards personal hygiene and an ambivalent attitude towards sanitation. Our study
demonstrated the ability of the mixed-methods approach to assess and distinguish an organisation's
prevailing food safety culture into identified classification levels (reactive, active, proactive). Specifically,
storytelling elicited respondents to share stories, which reflected the food safety and hygiene control
attitudes.

1. Introduction
Food safety is a global concern; the World Health Organisation
(WHO) estimates that each year 600 million foodborne illness in-
cidences occur worldwide (WHO., 2015). The highest burden of
foodborne illnesses per population is in transitioning countries,
particularly in Africa (WHO., 2015), as evidenced by inconsistent
food safety (FAO, 2007; Kussaga, Jacxsens, Tiisekwa, & Luning,
2014). Kussaga et al. (2014) reported that 83% of the microbial
cases, including dairy products, reported in African countries,
exceed microbiological limits. This is worrisome since dairy prod-
ucts significantly contribute to the human diet and are consumed
by all population groups (Chimboza & Mutandwa, 2007;
Papademas & Bintsis, 2010). Additionally, dairy products are
easily perishable (Demirbas, Cukur, Yildiz, & G€ olge, 2009) and are
highly vulnerable to contamination (Chimuti, Midzi, Njage, &
Mugadza, 2016; Papademas & Bintsis, 2010). Therefore, the food
industry and regulators are putting significant efforts on improving
food safety management systems (FSMS) and food safety perfor-
mance (Consumer Goods Forum (CGF) (2011); Kussaga et al., 2014)
in the dairy industry. However, FSMS are not always effective, as
demonstrated by recurring food safety problems (e.g. Chimuti et al.,
