Birds Eye is withdrawing 3 of its products from Irish supermarket shelves.
The company has announced that one of its meals - a Chilli Con Carne that was sold only in Belgium - was found to have 2% horse DNA in it.
The product was made at the Frigilunch plant in the Netherlands.
As a precaution Birds Eye says it is withdrawing its spaghetti bolognese, shepherds pie and beef lasagne products from supermarkets in Ireland and the UK.
This is because they are made by the same plant.
Products will not be replaced
In a statement the company said "Whilst this is not a food safety issue, it is clearly unacceptable".
"As a precautionary measure in the UK and Ireland we will withdraw all other products produced by the same supplier" it added.
The products being withdrawn are:
- Traditional Spaghetti Bolognese 340g
- Shepherd’s Pie 400g
- Beef Lasagne 400g
It says the products will not be replaced until they have finished the investigations.
The firm says that since the first discovery of horsemeat in some beef products, Iglo Foods Group - the parent company of Birds Eye - have been checking the integrity of their own beef products.
