The parasite arrives at a fragile moment — herds already thinned by drought and economic pressure, trade borders already sensitive — reminding us that the victories of science and agriculture are not permanent possessions but ongoing commitments. What was once eliminated through sustained collective effort must now be defended again, and the cost of forgetting is measured in flesh, livelihoods, and the quiet unraveling

Consumers may face higher beef prices due to reduced cattle supply, increased veterinary and containment costs, and potential supply chain disruptions. Trade restrictions could limit beef availability and increase import costs.
