A word of warning...From a retired Hazardous Materials Consultant formerly with Arthur D. Little. Inc. Cambridge, MA. The Government is not going to protect you from the Chemical lobby in Washington.
There has been a move to remove bis-phenol A from plastic food & beverage containers. However a more serious concern lies with the flame retardant system used in plastics.
Antimony oxide & DecaBromo BiPhenyl Ether are a more dangerous concern. This flame retardant system does leach into packaged food from the plastic.
These toxins are not only cumulative, but have deleterious effects on the body.
Kidney & bladder, liver, spleen and lungs can be affected. Also of interest is the effect these chemicals have in decreasing the bodies ability to metabolize fat.
Drink out of glass only. Avoid foods packaged in plastic.

I've been saying this for ages. Food/liquids and plastic should never meet. Especially in a microwave.
