The results of tests on the first 25 samples of products produced in Bulgaria and sent for testing for the presence of horsemeat found it in four, Bulgaria’s Food Safety Agency said on March 12 2013.
This represented four products from two meat-processing plants, the agency said.
The agency is investigating the suppliers to identify the offender.
As a member of the European Union, Bulgaria has sent 100 samples for DNA analysis, to be completed by the end of March 2013, to establish the illicit presence of horsemeat.
The products are not dangerous for human consumption, however, all available batches being recalled because the products mislead consumers, the agency said.
