Lawsuit: Meat alternative Quorn can make you violently ill

Quorn, a popular meat alternative sold at grocery stores nationwide, can cause allergic reactions that make people violently ill and should carry a warning on its label, according to a lawsuit filed by the Center for Science in the Public Interest.

CSPI says reactions range from vomiting and diarrhea to difficulty breathing.

Quorn, sold in different shapes and styles to simulate a variety of meat products from hot dogs to "chicken-style nuggets," is made from a fungus found growing in England in the late 1960s. The company's web site says Quorn products have been sold in the U.S. since 2002 and are now the biggest selling frozen meat-free alternatives in this country. Quorn has been sold in Great Britain since 1985.
