Kevin Kampwirth writes at Mental Floss:
When news broke earlier this year that a spate of European supermarkets had been selling frozen beef products adulterated with horsemeat, a large portion of the Western world collectively wretched. A couple of the products in question—frozen hamburger patties and beef lasagna—showed horse DNA at levels ranging from trace amounts up to 100 percent, and were quickly pulled from freezer cases as the slaughterhouses of origin were investigated. The plot thickened this week after inspectors in the Czech Republic reported that samples from Ikea’s voraciously consumed meatballs turned up evidence of horse DNA, prompting the Swedish mega-retailer to halt sales of its marquee offering in 14 European countries.
As EU authorities try to make sense of the scandal and call for stricter oversight of Europe’s notoriously unregulated meatpacking industry, millions of people around the world are likely wondering what the big fuss is. Despite the notion of horses as pets and companions, horsemeat is widely and willingly consumed in countries ranging from Mexico to China to Italy.
