(CNN) -- High-stakes lawsuits, overlapping investigations and a bitter battle over blame are spreading across Europe in the wake of a scandal that has rocked the meat industry. Horse meat was discovered in products that are supposed to be 100% beef, sold in Sweden, the United Kingdom and France. On Sunday, a major company under scrutiny called one of its suppliers a "villain" responsible for the fraud. The supplier, in turn, insisted it was "fooled" by a subsupplier. While authorities say there is no immediate cause for health concerns, the discovery was a new shock to an industry already reeling from a bombshell last month when Irish investigators found horse and pig DNA in numerous hamburger products.
