In this chapter, food safety is portrayed as an intrinsic component of food security and food systems. The objective is to discuss the ‘commercial restaurant’ system and the ‘kitchen worker’ subsystem from the perspective of building resilience in food safety. Relationship maps built for the system and subsystem guide the presentation and discussion of structural, organisational, social and symbolic aspects and elements. Resilience investigation is based on the references of the International Risk Governance Centre Resource Guide on Resilience and current and emerging topics related to food safety, such as risk perception of foodborne diseases, cognitive illusions, sociological aspects, social dimension of taste, humanisation and working conditions and precariousness of work in kitchens. In the final section, a list of recommendations for building resilience in commercial restaurants is presented to help researchers, decision-makers and practice agents apply this concept in their fields of expertise.
