BERLIN — A horse meat scandal that started in Britain and Ireland is now unnerving consumers around Europe. DNA tests have revealed that beef tainted with horse meat has made it into supermarkets in 13 European Union nations. Stores, schools, and hospitals are scrambling to remove some meat. And there are calls for tighter regulation of Europe's complex food supply chain.
The horse meat scandal started in Ireland and the United Kingdom in January, but has since spread all around the EU. DNA checks on beef have found that some products, including hamburgers, contained as much as 30 percent horse meat. The list of tainted products has since widened to include frozen lasagna, tortellini, and bolognese sauce.
