An escalating consumption of animal products characterizes contemporary Western society, resulting in severe environmental consequences and heightened exploitation of animals. Among these issues, livestock production stands out as particularly detrimental due to its significant climate impact and land usage. Paradoxically, the Swedish organic food sector positions cattle as central to achieving sustainable food production. This article delves into the strategies employed by organic organizations to legitimize the consumption of cattle’s meat and dairy. The aim is to examine how Swedish organic organizations produce knowledge of sustainability, and how these sustainability constructions are intertwined with anthroparchy, a system of power relations between humans and cattle. Furthermore, the study investigates how cattle’s agencies and bodies are portrayed. Interviews, documents and media material from organic organizations in Sweden are analyzed to explore how carnism, norms of eating cattle’s meat and dairy, is maintained. The analytical framework applied is rooted in critical animal studies and draws inspiration from Foucauldian discourse analysis, examining the interplay between power and knowledge. The findings reveal that certain environmental aspects are emphasized to reinforce the norm of keeping cattle for food production, while other dimensions are overlooked. Organic organizations represent cows as active subjects transforming their environment to legitimize their status as consumable commodities. The findings also show how carnistic norms limit the organic sector’s ability to achieve environmental objectives. This study underscores how anthroparchy, the dominant power structures between humans and cattle, is reproduced in the Swedish organic context through sustainability discourses that emphasize the subjectivities of cattle.
