Can I microwave Styrofoam for 30 seconds?
You can surely microwave Styrofoam for 30 seconds, but not more than that. If the temperature of the material reaches 200 degrees Celsius or more, the Styrofoam will start to melt and release toxic chemicals that can leach into your food and make it extremely harmful for your health.
Is melting Styrofoam toxic?
Polystyrene is considered safe for food use when in a solid state. However, heating can cause chemicals to leach from the foam and into the food. Eating the contents of a melted foam container one time is unlikely to cause harm. However, repeated exposure, which can be cumulative, can be a health risk.

But over the past several years, there has been a growing backlash against single-use polystyrene containers due to environmental and potential health concerns.
Does the FDA require plastic containers to be tested?
So it closely regulates plastic containers and materials that come into contact with food. The FDA requires manufacturers to test these containers using tests that meet FDA standards and specifications. It then reviews test data before approving a container for microwave use.”. — Harvard Medical School.
Can you put plastic cups in the microwave?
The Food and Drug Administration (FDA) does regulate plastic and polystyrene containers, cups, and plates and tests their safety and use in microwave ovens. Those deemed suitable receive a microwave-safe label indicating they have been tested for safety in the microwave. Look for the microwave-safe labeling on any styrofoam or polystyrene containers before putting them into the microwave.
