Madrid.—Spanish authorities have seized a ton of hamburgers in the Canary Islands that contained horsemeat despite not being labelled with it, an official said.

The meat -- about 7'000 hamburgers in total weighing just over one ton -- was destined for eateries in the Canaries, a major destination for foreign tourists. “They are now off the market and will not be eaten by anyone,” the regional government's trade and consumer affairs director Gustavo Matos told a news conference.

He said the Canaries authorities seized the burgers after a warning from a Spanish government watchdog which certified that they came from a known distributor of products containing horsemeat.
