"The FSA has been made aware of the survey results in which equine DNA was identified in some beef burgers and is working with the Food Safety Authority in the Republic of Ireland to investigate the issue.
"However, at this stage it is not believed to be a food safety risk.
We are aware that investigations are ongoing to ascertain how or why horse meat was used in the products."
