LOS ANGELES (Reuters) - Sushi is more popular than ever before but eating it "has become the new Russian roulette" in terms of safety, a group campaigning against mercury in fish said on Monday.

Eli Saddler of gotmercury.org, a campaign of California-based Sea Turtle Restoration Project, went to six top sushi restaurants in Los Angeles to test mercury levels in the fish they serve.

"The level of mercury in tuna these restaurants serve is so high they should be keeping this food off their lists," Saddler said. "Eating sushi has become the new Russian roulette."
