H5N1 avian flu infects cows with just 10 viral particles, highlighting systemic gaps in zoonotic disease control

The emergence of zoonotic diseases in industrialized livestock systems has historical parallels in colonial-era practices that disrupted Indigenous land management and introduced foreign livestock. These disruptions created ecological imbalances that facilitated disease outbreaks, a pattern repeating today in industrial dairy systems.
The H5N1 outbreak in U.S. dairy cattle is not an isolated event but a symptom of a larger systemic failure in global zoonotic disease control.
Industrial livestock systems, shaped by colonial agricultural legacies and driven by profit, create ideal conditions for viral spillover. Indigenous and smallholder farming practices, which emphasize ecological balance and animal welfare, offer alternative models that could reduce these risks. Integrating traditional knowledge, strengthening interdisciplinary public health infrastructure, and promoting regenerative agriculture are essential steps toward a more resilient and just food system. The low infectious dose of H5N1 underscores the urgency of rethinking our relationship with animals and ecosystems, moving beyond techno-scientific fixes to address the root causes of disease emergence.
