DUBLIN (AP) — So hungry you could eat a horse? Chances are, if you've regularly consumed processed-meat products in Europe, you already have.

Since Ireland published surprise DNA results on Jan. 15 showing that a third of frozen "beef" burgers in Ireland contained at least a trace of horse, food scientists in more than a dozen countries have found the animal trotting into products where it was never meant to roam.

Daily revelations from an ever-increasing menu of supermarket, catering and restaurant goods have taught the world one lesson: When minced up with other meat or slathered with spices, consumers cannot tell equine from bovine in the food chain.

MEATBALLS

Well, IKEA never did call them beef balls. The Swedish furniture giant has discovered that its signature cafeteria dish — spiced meatballs of mixed beef and pork — also might contain horse. Ikea said Monday it has suspended all meatball sales in Sweden and plans to withdraw stocks of frozen "Kottbullar" meatballs traced to a specific production batch from stores in 13 other nations: Belgium, Britain, Cyprus, the Czech Republic, France, Greece, Hungary, Ireland, Italy, the Netherlands, Portugal, Slovakia and Spain. The IKEA meatball controversy, like the other suspect products below, has yet to leap the Atlantic.

BURGERS

This is the product that started the January stampede to Europe's DNA labs. Irish authorities doing a random quality check were shocked to find horse meat in frozen burgers produced for five Irish and British supermarkets, and eventually traced the source to Poland. The Irish producers' top two customers — Burger King's British, Irish and Danish restaurants and the British supermarket chain Tesco — quickly took their business elsewhere.

PIZZA

There's something rotten in Denmark, but it's not the meat itself. The Danish Veterinary and Food Administration says a product enigmatically described as "pizza meat" and sold by the Harby Slagtehus meat wholesaler contains cow, pig and horse. The company insists that its customers in pizzerias across Denmark knew the topping contained horse, even if that little fact was nowhere on the ingredients list. Government vets don't believe a word of that.

SPAGHETTI BOLOGNESE

Better make that "bolo-neighs." Many of Europe's leading makers of microwaveable frozen foods — including Birds Eye of Britain, Nestle of Switzerland, and Findus of France — found that some suppliers had mixed horse into the ground beef used for Europe's most ubiquitous pasta sauce.

PASTA

Not to beat a dead horse, but Europe's food-testing labs are indicating that any factory-made pasta product containing "beef" sauce or filling might be horse in drag. Among those caught at the DNA finish line are the frozen "beef" lasagnas of Birds Eye; Nestle's Buitoni brand of ravioli in Italy and fusilli in Spain; and Combino-branded tortelloni and penne in Austria. France's Comigel blamed the discovery of up to 100 percent horse in its "beef" lasagnas — sold under other brand names, including Findus and Tesco — on a complex supply chain stretching from its Luxembourg factory back via Dutch and Cypriot middlemen to Romania horse butchers.

PASTRIES

Thank goodness there's no such thing (yet) as a beef doughnut. In Spain, Nestle's recall of products includes meat-filled, semicircular pastries called empanadas.

PIES

You might be surprised to find horse meat hiding under a frilly layer of potato. British-style cottage pies, with gravy, beef and carrots under the smashed spuds, have been withdrawn from scores of school cafeterias in England, Wales and Scotland after DNA tests found horse meat inside. France made similar discoveries in its potato-topped pie called hachis Parmentier.

VEGETABLES

Mom might tell you to eat your vegetables, but the Nestle product recall in Spain included meat-stuffed peppers.

KEBABS

Once you've blended a handful of meats, does one more really matter? The Austrians found horse in kebab meat produced by a Vienna firm, Lilla Gastronomie, that was supposed to contain a blend of only beef, pork and turkey.

SAUSAGES

Fry 'er up: Despite sausages' worldwide reputation as a favored destination for mystery meat, only Austria has found equine DNA hiding in sausages, in two brands made by Josef Freitag, aka "Joe Friday."
