Global agro-food trade grew strongly during the first globalisation. The increase in demand, the fall in trade costs, liberal policies and technological advances explain this expansion in trade. Within this context, this study analyses the formation and evolution of the international market of a special product: meat. It is a peculiar product because it is perishable. Furthermore, it is important to point out that the increase in its trade was based mostly on the strong demand in the United Kingdom, which acquired an almost monopsonist position, and also on the diffusion of mechanical refrigeration. This enabled the countries of the Río de la Plata, particularly Argentina, together with Australia and New Zealand to become world leaders in meat exports.

This paper examines the meat supply system in Rio de Janeiro from the late nineteenth century to the 1920s. For a period of time the city's monopoly over meat processing and retailing guaranteed a steady supply at predictable prices. However, at the turn of the century, ‘interlopers’, as municipal officials labelled those who attempted to introduce their product into Rio's market, began to question this century-old monopoly. Hence, for a relatively short period, Rio de Janeiro implemented a number of measures: curtailing the long-standing custom of clandestine slaughtering; establishing a centralised and somewhat regulated public abattoir system; and, finally, introducing meat-packing companies. This study considers these developments by undertaking a broader inquiry into how they affected per capita meat availability in Rio de Janeiro from the 1890s to the 1920s.
