Supermarkets Tesco and Asda were found to have large quantities of lamb from New Zealand and Australia.
A Borders farmer has hit out at some supermarkets, after a survey found some are still stocking large quantities of imported lamb.
Stephen Withers, who farms near Jedburgh, says many fields are full of lamb right here, and there is no need to find it elsewhere.
"We are selling lambs for £25 less than last year, in the Borders there is a large number of lambs still on the farm, and it is so disappointing to think they are bringing lambs half way around the world to supply what we have plenty of just in this area.
"Supermarkets are our main outlets and without them none of our lamb would be sold. The butchers take a very small proportion.
"It is so disappointing to think that they are not supporting local farmers when we have so much quality lamb in this area."
A survey of supermarkets in the Scottish Borders has found that they are still selling substantial quantities of imported lamb.
NFU Scotland, who conducted the survey, say that at a time which is hugely challenging for sheep farmers, they need commitment from big supermarket chains.
Morrisons was the only supermarket to stock only British lamb. By comparison, Asda and Tesco have substantial quantities of New Zealand and Australian lamb on their shelves.
Opening sales of 2013 for prime sheep have seen market prices for the 2012 lamb crop fall to their lowest level since late 2009.
A major supermarket development is being planned for Melrose.The Co-operative group want to turn the St Dunstans petrol station and neighbouring 'The Whole Lot' shop into a class one supermarket.
They have lodged a planning application with Scottish Borders Council seeking permission for a partial demolition and a change of use for both premises.
The new supermarket for Melrose will be discussed by planners this Autumn.
Developers say they will appeal against a decision to refuse plans for a 20 million pound supermarket on the outskirts of Dumfries.
Dumfries and Galloway Council has rejected proposals for the scheme which would be sited on the town's Annan Road.
Town centre traders had previously raised concerns that if approved the store would affect their business.
Developers CWP say they remain focused on the development.
