Styrofoam, also known as polystyrene, is a lightweight and inexpensive material that is commonly used for food packaging. However, it is important to note that microwaving food in styrofoam containers can pose potential health risks.
Chemical Leaching
When styrofoam is heated to high temperatures, such as in a microwave oven, it can begin to melt or break down. This process can cause toxic chemicals, including styrene, to leach into the food. Styrene is a known carcinogen and has been linked to a range of health problems, including cancer, reproductive issues, and developmental disorders.
Other Health Concerns
In addition to styrene leaching, microwaving food in styrofoam containers can also release other harmful chemicals, such as benzene and toluene. These chemicals have also been linked to a variety of health problems, including cancer, respiratory issues, and neurological damage.
What to Do if You’ve Microwaved Food in Styrofoam
If you have accidentally microwaved food in a styrofoam container, it is important to discard the food and the container immediately. Do not eat the food, as it may have been contaminated with harmful chemicals.
Safer Alternatives to Styrofoam
There are several safer alternatives to styrofoam containers that are available for microwaving food. These alternatives include:
- Glass containers
- Ceramic containers
- Plastic containers that are labeled “microwave-safe”
- Paper plates or bowls
While styrofoam containers may be convenient for food packaging, it is important to be aware of the potential health risks associated with microwaving food in these containers. To protect your health, it is best to avoid microwaving food in styrofoam containers and opt for safer alternatives instead.
Reheating food in a microwave is the most convenient way to reheat food. However, as you are already aware, not everything is suitable for microwave use. Takeout and leftover food from your restaurant are frequently packaged in plastic foam containers. Not every foam container is the same, nor are they all safe to use in the microwave.

Can Styrofoam go in the oven?
Individuals should not put EPS foam in the oven. The material may warp and soften at very high temperatures. Similar to using a microwave, heating EPS foam in an oven can also release harmful substances into the food.

Is Styrofoam toxic when heated?
What does heat do to Styrofoam?
What chemical does Styrofoam release when heated?
Is it OK to microwave Styrofoam?
Does styrofoam melt?
Yes, though Styrofoam will eventually deform and then melt, it’s reasonably heat resistant. That’s why they put hot coffee and hot food in it- it stays warm and insulated inside, but won’t burn your fingers on the outside (in theory, at least – always be cautious when picking up a hot coffee or meal, even in Styrofoam packaging).
Is Styrofoam heat resistant?
Yes, styrofoam is heat resistant. Styrofoam is composed of a lot of little air bubbles. These air bubbles trap heat, making it impossible for heat transfer to happen. Since styrofoam is lined with aluminum foil on one side, the foil reflects and absorbs heat. A poor heat conductor, air makes up nearly 95% of Styrofoam.
Can you burn styrofoam?
As it turns out, you can burn Styrofoam—but you probably shouldn’t. When burned, Styrofoam emits a number of harmful chemicals. Inhaling these chemicals can cause a variety of health problems, including headaches, dizziness, and respiratory irritation.
Why does styrofoam burn so fast?
The tiny particles that make up styrofoam need much oxygen to burn. In controlled environments like fireplaces, styrofoam will burn quickly. Styrofoam burns slowly in uncontrolled environments due to a lack of enough oxygen. Polystyrene, a material from the plastic family, forms styrofoam.
