This is just a personal opinion, but...only consider food-safe those materials which the company, in this case, Shapeways, considers so (and you can/should use other sources of information as well). Which seems to be only ceramic, here. I tend to read all documentation, from whatever the company, that is, the material safety PDF, and compare with other sources. But going for an usage/safety already non recommended by the company producing it... does not make sense at all to me.
In some places is recommended to those having home printers to have the room windows pretty well opened while producing the 3D print, due to the gases produced in the home 3D printers (PLA a bit better than ABS in that matter, it seems) process, which seem to not be very healthy. Once as a solid figure, well, I guess it might be safer, but imho, that a known toy maker used the material does not grant anything. First of all, regulations do change, evolve, new detected harms are discovered, etc. There are materials that are not toxic in normal conditions, but due to its components not being that safe under certain conditions, the thing might become come more harmful. One of the conditions that might make it not safe, is heat, temperature. And food is hot in many cases, be it liquid or solid. And there are many other factors. IMO, using each material with the usage which the company specifies and recommends, is a must. I mean, doing that, at least, as a minimum. And from a legal point of view, the company is recommending you to not do certain usage, so in most cases they would be free from any issue if you take unnecessary risks and certain damages do arise.
PD: Very nice website and catalog
...And, I have personally no clue about the accuracy of the following article, but it talks about PLA and ABS and the toxic matter.
