The multinational business Cargill is looking at buying a 50 per cent stake in Teys Meat Group, which owns the Naracoorte abattoir.
Cargill hopes to buy out Consolidated Meat Group's share in the company that owns meat processing facilities in South Australia and Queensland.
The move is before the Australian Competition and Consumer Commission.
Teys' chief executive Brad Teys says there could be many reasons why Cargill wants the merger.
He says nothing is definite yet.
