Microwaving food has become a staple in our fast-paced lives. Imagine opening your fridge and seeing last night’s dinner from your favorite restaurant neatly packed up inside a Styrofoam container.
You’re excited to enjoy tasty leftovers but are wondering if it's safe to put Styrofoam in the microwave when reheating your food. Let's dive into this topic, debunk the myths surrounding it, and discover if it’s safe to microwave Styrofoam.
Styrofoam is a popular packaging material known for its lightweight and insulating properties. Many take-out containers from restaurants are made from expanded polystyrene foam, otherwise known as Styrofoam. This material comprises about 95% air, making it lightweight but not impervious to heat. This means it can pose potential hazards when exposed to high temperatures.
In a nutshell, you should not microwave Styrofoam unless it has a microwave-safe label on the container. The microwave-safe symbol is an outline of a microwave with wavy lines; this indicates that the container has been FDA-approved for microwaving. Let’s go over some more guidelines you should follow when it comes to microwaving Styrofoam.
Microwaving Styrofoam that is not labeled microwave-safe can cause the material to melt or release harmful chemicals like styrene into your food if not handled correctly. Styrene is a potential carcinogen (something known to cause cancer) and may pose health risks when ingested.
Overall, Styrofoam plates, containers, and cups are not the best option when it comes to safely reheating your food. Apart from the harmful chemicals found in Styrofoam, if the containers are not microwave-safe, they run the risk of catching fire or melting. This is especially true if you heat them for too long.
