CONSUMERS have been urged to support retailers who guarantee their milk is local, as some supermarkets could be getting their 'Irish' milk from the North.
The Irish Farmers Association (IFA) has asked consumers to buy from supermarkets that stock milk farmed and processed in the Republic.
They published details of which major retailers stock milk that carries the National Dairy Council's (NDC) mark – guaranteeing it is produced in the State.
Milk without this mark is likely farmed or processed in Northern Ireland, as the NDC mark is now used on most milk supplied from the Republic.
Tesco and Supervalu were found to sell only NDC-marked milk for both branded and own-brand milk. But Marks & Spencer was singled out for selling no NDC milk at all.
Dunnes Stores was also criticised for selling own-brand milk that isn't NDC-marked, even though the branded milk it sells does carry this guarantee.
"Dunnes Stores, disappointingly for a long-established Irish retailer, is not offering their budget-conscious consumers NDC-marked Irish milk under their private label," the IFA said.
Aldi was found to have a mixed record with NDC-marked milk available in all pack sizes.
Lidl, meanwhile, only offered NDC-marked one-litre packs of milk, but its two-litre and larger packs were not covered.
