Here's one they weren't expecting — meat pies with no meat.
When officials in Iceland began hearing about horsemeat being secreted into beef products around Europe, they decided to run tests to ensure the same thing wasn't happening in Iceland.
Icelandic meat inspector Kjartan Hreinsson says his team didn't find any horsemeat, but one brand of locally produced beef pie left it stumped: it contained no meat at all.
"That was the peculiar thing," Hreinsson said in a telephone interview Friday. "It was labelled as beef pie, so it should be beef pie."
Hreinsson said it appeared to be some kind of vegetable matter. He said the mystery pie was traced to a firm in western Iceland and the case had been handed to municipal authorities.
