Supermarket giants Coles and Woolworths have appeared before a parliamentary inquiry in Australia to explain their ongoing milk war.
In January, Coles slashed the price of milk to $A1 a litre for its generic brand, ABC reports.
Coles says the cost-cutting will not affect the long-term viability of farmers, as sales have increased.
But Woolworths, which claims it matched the discounted price only to remain competitive, says it is worried about the long-term future of dairy farmers.
