Recently it was uncovered that in 2005 the EPA discovered some vinyl lunchboxes contained unsafe levels of lead, but the EPA did not release the study until an AP Freedom of Information Act request. They found some lunchboxes with a lead content of 600 parts per million(ppm) while the "safe" level is 9600 ppm.
While I'm not excited about even the safe level of lead, I am excited about these great canvas lunch sacks from ECOBAGS. $6 for a canvas lunch sack or one dollar more for organic canvas. My advice, pick the organic canvas!
Check out these lead-free bags for kids. Reusablebags.com has nice water bottle options too.
I use the organic canvas bags and have been very happy with them. I actually ordered extra to give as little gifts. I like being able to machine wash them and they look like new after much use. I think the Mimi the Sardine bags are adorable but there sure is something special about organic cotton. I recommend these bags!
I saw a notice about this issue at my child's preschool. They recommended getting a lead test kit at the hardware store. I like to pack my kid's food in unbleached wax baggies that go right into his backpack. But the those organic eco bags look great! They also sell organic string bags in fun colors.
