The ontological politics of kosher food: Between strict orthodoxy and global markets

As markets for kosher food have expanded globally in recent decades, multiple rabbinical authorities and kosher certification bodies have emerged to protect – and project – the boundaries of what is permissible for Jewish consumers. In this paper, we explore how, as kosher food has become more widely available in supermarkets and global food businesses, there has been a concurrent growth in demand within some Jewish communities for kosher goods produced in line with ever more strictly observed Jewish dietary laws (kashrus). Drawing on research on kosher markets and consumption practice in Manchester in the North of England, UK, we interrogate the multiple kosher ontologies enacted in markets, and the wider effects of this multiplicity on consumption practice(s). We conclude with some theoretical reflections on the ontological politics of qualification in markets.
