The affected (受影响的) bags were found in Florida.But Publix has more than 1，000 stores across America.Publix says that its bags don’t break any laws about lead levels, but that they have asked the makers of the bags to reduce(降低) the lead levels in them. The bags with the highest levels of lead had beautiful designs and many pictures.Plain reusable bags without them are found to have little lead.People worried about lead levels in reusable bags can turn to cloth.Paper bags are also a good choice, since paper can be reused. 1.
