the chemicals that are involved in the milk scandal are quite different than the melamine resin coated wood we are using.

the same material (melamine resin) is quite common in kitchen products

from wiki:
Melamine resin is often used in kitchen utensils and plates (such as Melmac). Melamine resin utensils and bowls are not microwave safe, as they absorb the microwave radiation and heat up.[1] As with all thermosetting materials, melamine resin cannot be melted and, therefore, cannot be recycled.
as for the wood off-gassing formaldahide.. no idea but unless you have no ventilation it shouldn't be a problem.
