Burger King has stopped using the firm which had been caught supplying horse meat in their beef burgers to consumers.

The horse meat fiasco occurred last week when the meat was meat was found in popular UK super market chain Tesco's beef burgers.

"People in our country will have been very concerned to read this morning that when they thought they were buying beef burgers they were buying something that had horse meat in it," said Prime Minister David Cameron in Parliament according to Reuters."This is a completely unacceptable state of affairs."

The Associated Press reported that the beef burgers also had traces of pig DNA in the burger products. Authorities are saying the burgers were made of approximately 30 percent horse meat.

Out of 27 burger products analyzed, 10 of them contained traces of horse DNA and 23 contained pig DNA.

Reuters reported that other chains such as Aldi, Lidi and Iceland also were selling beef products with horse meat in it.

The supplier is called Silvercrest products and on its website, Burger King stated they would no longer use the products in Britain and Ireland.

"This is a voluntary and precautionary measure," Burger King said. "We are working diligently to identify suppliers that can produce 100 percent pure Irish and British beef products that meet our high quality standards."

Burger King said that they were still interested in looking for other Irish suppliers to replace the horse meat supplier.

"Burger King has said they're looking at other Irish sources to try and source and replace this," John Bryan, president of the Food Safety Authority of Ireland (FSAI) said to RTE, an Irish state broadcaster. "Several of them would have the capacity to take up an 8,000 ton burger contract and there would be plenty of availability of meat to fill this contract."

Simon Coveney who is Ireland's agriculture minister added to RTE "Burger King have said that they do want to source beef from Britain and Ireland because they realise the high standards here."

Silvercrest is a subsidiary of ABP and the group said to the BBC that they were investigating the incident internally.  

"The Food Safety Authority of Ireland (FSAI) said the contaminated meat had come from two processing plants in the Irish Republic - Liffey Meats and Silvercrest Foods - and the Dalepak Hambleton plant in Yorkshire," reported The BBC.

Both Dalepak and Silvercrest said they have not traded in horse product and are launching an investigation on two third party suppliers.
