The food processing group which owns the Irish supplier Silvercrest - dropped by Tesco after an investigation into how horse DNA ended up in its frozen burgers - says it has introduced new measures to audit where its meat comes from.
Tesco's internal investigation found Silvercrest supplied meat that did not come from the list of approved suppliers, or from the UK or Ireland.
The ABP Group said: "We have put in place new procedures to audit all our third party suppliers."
