The Calvo Group is a backward vertically integrated group of companies dedicated to fishing, processing and distribution of canned goods. The group is centred on Luis Calvo Sanz, S.A., a company established in 1940 in Carballo.[1][2]
Grupo Calvo operated in the town of Guanta, Venezuela under the name "Atuneras del Oriente" (ATORSA) and, later, as Industrias Calvo Conservas de Venezuela S.A.[3] Between 1991 and 2001, they had to temporarily close due to lack of tuna.[4] A few years after its reopening, in 2004 it had labor conflicts with part of the workforce, as it wanted to substantially reduce it.[5] That same year, it suffered an armed attack that ended up setting fire to the Venezuelan facilities, causing considerable material damage.[6]
