If safety is the ultimate concern, maybe Ironman just needs companies to have a certificate product liability insurance. Of course, in a global market, that gets tricky.

I doubt the bento box people are actually buying product liability insurance. I also doubt they are getting CE certified, if they are European, and that's a real pain for a lot of products.

At some point it's better to simply say buyer/user beware. I've noticed once you actually go down the legal liability route, and if you take that as a principled stand, you really end up wasting a lot of money paying other people to hand you papers that still don't make your products any safer. I'm involved in this professionally on multiple levels and it's really just something that adds on costs to the consumer without increasing safety.
