The meat from the 22,000 cows being culled due to Mycoplasma bovis will end up in supermarkets.
MPI has announced the mass cull of beasts from infected farms in a bid to rid the country of the disease.
Mycoplasma bovis makes the cows sick but doesn't affect their by-products meat and milk.
Federated Farmers Southland meat and wool chair Bernadette Hunt told Mike Hosking this disease is everywhere else in the world, except Norway - and prior to this outbreak, New Zealand.
"Those animals are in the food chain along with the milk and there is no problem. It has been around for a very long time."
