The European Commission says nearly five percent of beef products sold in all 27 member countries of the European Union were contaminated with horse meat.

The commission issued a statement on Tuesday saying it found horse-meat DNA in 193, or four-point-66 percent, of four-thousand-144 beef products sold in the EU.

Meanwhile, 16 or less than one percent of three-thousand-115 products tested were found to contain phenylbutazone, which is known to pose health risks to humans.

However, spokesman Frederick Vincent of the European Commission said the amount of phenylbutazone is not at a dangerous level, adding a consumer would only face a serious health risk if he or she ate hundreds of horse burgers over several months.
