Tesco drops supplier over horsemeat in value burgers

Meat in Tesco burgers which was found to contain horse DNA did not come from a list of "approved suppliers", the supermarket chain has claimed.

The retailer has dropped Silvercrest, part of the ABP Food Group, as a supplier, saying the "breach of trust [was] simply too great".

Tesco said it would introduce a DNA testing system for meat products to "ensure the quality" of its goods.
