The price war among supermarkets has stepped up a gear with many of the big retailers announcing they are reducing the price of their own brand milk products.
Lidl was the first of the three to announce the reduction on Friday, saying a two-litre carton of its own-brand milk will drop in price from €2.19 to €2.09.
Aldi also confirmed that it will be cutting the prices of all its own-brand milk products by an average of 10 cents.
From today, SuperValu and Tesco Ireland are to reduce the price of two-litre cartons of their own-brand milk from €2.19 to €2.09.
The president of the Irish Farmers Association, Tim Cullinan, has said farmers are very concerned again about the latest price cuts.
"We all empathise with consumers dealing with current inflation," Mr Cullinan said.
"But what we've seen here time and time again, when retailers look for a price reduction ultimately, it's the farmer that will pay and they will dispute this and say different things, but I've seen this for many, many years," he added.
"Whenever there is a price reduction, it finds its way back to the farmer," he stated.
Speaking on RTÉ’s Morning Ireland, he said we are seeing the start of a price war again.
"We have a small group now, a couple of thousand farmers left producing liquid milk, milk that is produced 52 weeks of the year and a very expensive product to produce," he said.
He said that farmers are leaving this business to move over into different milk production.
"If this trend continues, we will end up in a situation here in this country where we won't be producing liquid milk and retailers won't have Irish milk to be able to put on their shelves", he said.
