WASHINGTON (AP) -- California importer Frank Lettieri is being sued for not warning his customers that his balsamic vinegar contains lead. True enough, he says. But you would have to drink more than a pint of the vinegar every day to reach the government limit for safe exposure to lead. Most people just sprinkle a few drops onto salads or bread.Regardless, a voter-passed law in California says consumers have a right to know about lead and other harmful chemicals. “The ironic part is, it will kill you in California, but it won’t kill you in Nevada,” Lettieri says. “It won’t kill you anywhere else in the country.”
