MORE traces of horse DNA have been confirmed in beef products tonight - leading to the closure of a factory in Monaghan.
The ABP group said in a statement tonight that its investigations into the source of the horse meat have centred around two third party EU suppliers.
"Following receipt of this evening’s Irish Department of Agriculture results, we believe that we have established the source of the contaminated material to one of these suppliers," it said in a statement.
"However, because equine DNA has been found in finished products tested this week, we have decided that the responsible course of action is to suspend all production at the Silvercrest plant in County Monaghan with immediate effect.
The company added that this week’s production of meat has not been released from the plant.
"During the suspension of production, all staff will continue to be paid, and we will be working with the relevant authorities, management and supervisory team to complete our investigation," ABP added.
"We will continue to communicate with our customers and suppliers over the coming days."
