Staff working in BK restaurants in the UK have been told to box up Whoppers, Angus burgers and patties, and mark them with an “X” ready to be thrown away, reports The Sun

 Burger King was one of numerous supermarkets and cash n carries that bought burgers from Silvercrest – the Irish meat processor at the centre of the Horseburger scare. Inspectors found traces of horse DNA in burgers made at the factory and another owned by parent ABP.

However, customers at Burger King over the weekend were still being served burgers from the same supplier as always – Silvercrest – until new stock came in.

Managers were ordered to tell customers who were concerned that there might be horsemeat in their burgers that Burger King was taking all the “necessary precautions” to ensure quality.

Burger King has arranged a new supplier for most of its menu.
