According to official sources: "While M. bovis is a production-limiting disease, it poses no threat to human health or food safety.
"Fortunately, this disease is unlikely to impact on international trade as the disease is not a risk in animal products.
"Every other country in the world has M. bovis in their cattle herds. Evidence from overseas indicates this is unlikely to present a significant management problem for most farmers running extensive production systems."
Okay, not great, but that seems easily manageable to me. I am only a farmer though.
Apparently eradication could take 10 years, and cost around $500 million — and containment is equally pricey. Include the impact to the economy, it could be $1 billion.
