A draft law that would enable any EU country to prohibit the sale of GM food was rejected by the European Parliament today.
Many farmers in Ireland use genetically modified feed for their animals.
And they believe a ban on animal GM feed could have a negative impact on their incomes.
But Sinn Fein MEP Lynn Boylan says we need to build a reputation as a country that does not genetically alter its food.
"What we would like to see is a move away from the use of GM feed, we believe that Ireland is in a lovely position to market itself as a 'green' brand and we know that some countries have already indicated with Irish food, because of the use of GM feed, they don't see it as a 'green' brand, particularly of meet so we would like to see farmers move away from it."
