Seafood represents an increasingly important source of animal protein in diets globally. Between 1950 and 2014, global annual per capita supply of seafood has more than tripled from approximately 6 kg to nearly 20 kg (FAO, 2016) driven largely by population growth and increasing incomes in developing nations (Bailey and Tran, 2019). Aquaculture growth, which already constitutes half of all seafood consumed by humans, is critical to meet increasing demand for fish (Troell et al., 2014). Concern among consumers and regulators over the safety and environmental sustainability of seafood, particularly in developed nations, has led to the development of stringent seafood safety standards in the global North, including voluntary standards overseen by private third-party certification bodies (Tran et al., 2013). While such standards may constitute barriers to participation in export markets by small-scale producers, they have catalysed upgrades to production and post-harvest handling practices of value chain actors in developing countries. The health burden of foodborne illnesses is a major concern in developing countries (WHO, 2015). The majority of this burden is linked to consumption of animal-source foods (Grace, 2015). As incomes rise, consumers in these countries are increasingly willing to pay a premium for safer foods (Birol et al., 2015). However, there is little empirical evidence on consumers’ willingness to pay (WTP) for seafood safety in developing countries, particularly in sub-Saharan Africa (SSA). Even less is understood about demand in SSA for the certification of products on food safety and environmental sustainability metrics, although awareness of food safety and environmental issues among higher-income consumers is rising. This dearth of knowledge makes it difficult to evaluate whether consumers’ demand for safe and healthy seafood from local markets in SSA can be harnessed to generate positive returns to producers. To fill these gaps in the literature, the current study assesses consumers’ WTP for food safety and sustainability certification of domestically marketed aquaculture products in Nigeria.
