Tesco: Three products had more than 60% horse DNA

We have carried out a number of tests on the product [Everyday Value Spaghetti Bolognese] and those tests identified the presence of horse DNA. Of the positive results, most are at a trace level of less than 1% but three showed significant levels of horse DNA, exceeding 60%. We have carried out further tests to ensure that there is no danger to health through the presence of potentially harmful bute. The test for bute was clear.
