Burger King has eventually admitted that the burger that they have been selling contained horse meat. They have been denying that they contained no horse meat with absolute assurance for more than a week.

However, it was later revealed that the burgers containing horse meat were produced by the Irish-based processing company called Silvercrest, which is part the ABP Foods Group.

Silvercrest provided meat to all of Burger King's restaurants in Ireland, the U.K. and Denmark.  

Burger King made a statment saying:

"Four samples recently taken from the Silvercrest plant have shown the presence of very small trace levels of equine DNA. Within the last 36 hours, we have established that Silvercrest used a small percentage of beef imported from a non-approved supplier in Poland. They promised to deliver 100 per cent British & Irish beef patties and have not done so. This is a clear violation of our specifications, and we have terminated our relationship with them."

Burger King's vice president, Diego Beamonte, also said:

"We are deeply troubled by the findings of our investigation and apologize to our guests, who trust us to source only the highest quality 100 per cent beef burgers. Our supplier has failed us and in turn we have failed you. We are committed to ensuring that this does not happen again."

ABP also released a statement of apology on Jan 16."ABP takes this matter extremely seriously and apologizes for the understandable concern this issue has caused," the supplier said.

Onwards, Burger King claimed it will find additional measures like DNA testing to make sure that no equine DNA shows up in its beef. 

However, none of the tainted meat was sold in the United States
