L. I. de M.  aFood defencebThe securitisation of the food supply.h[electronic resource]  c2025  aThe notion of food defence emerged in the USA following the terrorist attacks of 11 September 2001, reflecting the idea that the food sector constitutes a critical infrastructure for national security and that the food system must be defended against intentional acts, motivated by political or ideological reasons, that could cause large-scale damage to public health or the economy. This study draws on primary documentary sources on food defence, including government guidelines, laws, norms and regulations issued mainly in the USA, as well as secondary bibliographic sources related to the topic, and draws on insights from securitisation theory in order to show that food defence discourses, norms, guidelines and practices connect to a process of social construction of threats and risks, linked to the frameworks of bioterrorism and biodefence, subjecting the food sector to a process of securitisation. Based on this analysis, we aim to contribute, firstly, by deepening the problematisation of food defence, adding to the debate a political and security dimension. Without this discussion, we argue it is not possible to understand, rigorously and accurately, food defence’s defining core and its specificities within the conceptual constellation of food protection. Secondly, by resorting to the food defence case, we hope to contribute empirically to illustrate an expanded version of securitisation, drawing attention to the importance of a more eclectic and integrated look at the discursive and non-discursive aspects and the different logics that operate in the social construction of security.  aBioterrorism  aFood supply chain  aBiodefence  aFood defence  aFood protection  aFood terrorism  aSecuritization1 aOLIVEIRA, G.
