lead & pvc free?

i bought this insulated lunch bag at walmart for $2.88 to take on hikes. the tag intrigued me as it says "ULTRA SAFE pvc & lead free lining - meets FDA & CPSC lead free standards". for $2.88, i'm sold. just for kicks i looked to see what it's made of - polyurethane foam.

here's how the three materials compare:
lead - leaches into food & causes neurological damage
pvc - leaches phthalates into food, which has been shown to cause liver damage and birth defects in lab rats (the production of pvc also creates dioxin, the most potent carcinogen known)
polyurethane foam - highly flammable

polyurethane foam is used in almost everything - car seats, mattresses, pretty much anything squishy and comfortable. not to say it's safe just because it's used in a number of products, but after a brief google, i couldn't find any compelling health effects. so there's no real health risk...just make sure not to keep it near your camp fire.

but is it really lead & pvc free? surprise! it's manufactured in china, so your guess is as good as mine.
