How safe are reusable bags?

Here's a twist that may muddy the waters in the debate over plastic bag bans -- its a question about the safety of reusable bags. The Wegmans Food Markets chain in Rochester, N.Y., announced Friday that it will stop selling two reusable shopping bags designs because testing that indicates that they contain elevated levels of lead. The bags -- decorated with green pea and 2009 holiday designs -- are made in China. The supermarket chain has stores in New York, Pennsylvania, New Jersey, Virginia and Maryland. A consumer group urged other grocery chains to test their bags for heavy metals.
