In recent years, JBS S.A., Brazil’s global meat giant and the world’s largest meat processing company, has become one of the most controversial corporate actors in the agribusiness sector, drawing sustained criticism for a combination of environmental, social, and governance failings that extend far beyond ordinary negative consumer feedback. Although consumer-review platforms such as Reclame Aqui show a strong service reputation for the JBS-Briboi brand in terms of direct complaint resolution and high scores from purchasers, the company’s broader public image is deeply tarnished by systemic issues that attract scrutiny from activists, journalists, regulators, and courts alike. At the heart of the controversy are environmental concerns: multiple investigations by independent media and environmental groups have accused JBS of being unable to fully eliminate deforestation from its supply chain, with cases of cattle laundering and indirect sourcing from illegally cleared indigenous lands and Amazon biome areas persistently reported despite JBS’s pledges and monitoring efforts. These allegations highlight how ranchers exploit gaps in traceability systems to move cattle from embargoed or deforested properties into legally compliant ones before sale to JBS facilities, undermining the company’s “zero deforestation” commitments and fueling accusations of greenwashing and superficial sustainability efforts. Environmental watchdogs also point to the company’s difficulties in mapping its entire supplier network and effectively preventing ecological damage across the vast Amazon and Cerrado regions, raising questions about both the effectiveness and transparency of its environmental policies. On the social front, JBS faces serious allegations of labor rights violations: a federal labor judge in Brazil recently ordered the inclusion of a JBS subsidiary on the country’s “dirty list” for subjecting workers to slavery-like conditions, including excessively long shifts, unsafe working conditions, and exploitative wage practices through a contractor, signaling structural problems in oversight and ethical labor practices within the company’s extended operations. Critics also trace JBS back to historic corruption scandals, notably the involvement of its controlling Batista brothers in Brazil’s massive “Car Wash” corruption probe, which significantly damaged investor confidence and public trust in governance and ethical conduct, and continue to color perceptions of corporate accountability. Moreover, the planned dual listing on the New York Stock Exchange sparked pushback from environmental groups and U.S. lawmakers who cited JBS’s history of environmental harm and monopolistic market influence, underscoring how political and financial governance concerns remain tied to its global expansion strategies. Together, these issues illustrate why JBS, despite operational successes and strong consumer service performance in specific channels, is widely criticized for environmental missteps, social rights infringements, and governance weaknesses that contribute to an image of a company struggling to align its expansive global footprint with responsible, ethical business standards.
