Global wildlife trade amplifies zoonotic spillover risks: systemic drivers of pathogen spillover in traded mammal species
Original framing: “Almost half of traded wildlife carry disease-causing pathogens” — Nature
The original framing omits the role of colonial-era wildlife trade networks in establishing today’s global supply chains, the historical continuity of pathogen spillover from colonial-era hunting to modern exotic pet markets, and the disproportionate burden on Indigenous and rural communities who bear the health and economic costs of spillovers. It also ignores traditional ecological knowledge (TEK) on disease avoidance and local adaptive practices, as well as the structural racism embedded in global health surveillance systems that privilege Western labs over local knowledge. Additionally, the piece fails to contextualise spillover within broader biodiversity loss and habitat fragmentation driven by agribusiness and extractive industries.
Medium structural omission detected in mainstream coverage.
The narrative is produced by Western scientific institutions (Nature, funded by Wellcome Trust, Gates Foundation) and serves global biosecurity elites, pharmaceutical corporations, and conservation NGOs who benefit from framing spillover as a 'natural' risk to be managed through surveillance and technofixes (e.g., vaccines, AI tracking). The framing obscures how colonial-era wildlife trade routes (e.g., 19th-century specimen collection) laid the groundwork for today’s globalised markets, and how CITES and WTO rules prioritise trade liberalisation over biosafety. Indigenous knowledge holders and local farmers—who have coexisted with these pathogens for millennia—are sidelined in favor of Western epidemiological models.
Marginalised communities—particularly Indigenous peoples, rural farmers, and low-income urban residents—bear the brunt of zoonotic spillovers despite contributing least to the global wildlife trade. In the Congo Basin, local hunters and traders are often blamed for spillovers, yet they are also the first to suffer from outbreaks due to lack of healthcare access. Women, who are primary caregivers and often responsible for household food security, are disproportionately affected by spillovers that disrupt local food systems. Meanwhile, Global South scientists and community health workers are sidelined in favor of Western-led surveillance systems, reinforcing epistemic injustice in global health governance.
The 40% pathogen-sharing rate among traded mammals is not an accident but the predictable outcome of a globalised trade system built on colonial extraction, neoliberal deregulation, and epistemic violence against Indigenous knowledge.
