Beef burgers made by a company which had some of its products test positive for horse DNA have been withdrawn from primary schools in Caerphilly County Borough.
The Burger Manufacturing Company, based near Builth Wells, has had three samples prove positive.
Caerphilly County Borough Council has said its supplier, Powys-based company Holdsworth, has tested burgers supplied to its secondary schools and the results have been negative.
Results from tests on primary school burgers are being awaited and the council has withdrawn them as a precaution.
Holdsworth gets its products from the Burger Manufacturing Company, while it is in turn supplied by Farmbox Meats in Llandre, near Aberystwyth, which is under police investigation.
A spokesperson for Caerphilly County Borough Council said: “We have received correspondence from several companies that we use to purchase meat products from (Pasta King, Birds Eye and Freeza Meats Holdsworth) that DNA testing for the presence of horsemeat has been carried out on all meat products supplied to the authority – and that negative results have been verified.
“Holdsworth are pleased to inform us that negative results have been confirmed on all burgers supplied to the secondary sector within Caerphilly County Borough Council. We await the results from products supplied to primary schools from Burger Manufacturing Company, and have removed these from school menus as a precaution. As soon as these results become available, we will provide an update accordingly.”
The Welsh Local Government Association has said testing on food for schools would be “ratcheted up”.
