You should avoid microwaving Styrofoam, as it’s generally not considered safe. While some types of foam are labeled as microwave-safe, the professionals at Mr. Appliance® recommend against it.
Using foam vessels for reheating food in a microwave oven can be risky, and even if the Styrofoam is marked as safe, there’s always a chance of chemicals leaching into your food.
It’s better to use alternatives when heating food to ensure it’s truly safe to put in the microwave.
The best solution about Can you microwave styrofoam? is existing here. Microwaving styrofoam is a topic often met with confusion and concern. Many are unsure whether expanded polystyrene (EPS) foam is safe for such use. The debate revolves around the potential risk of chemicals leaching into food, with some fearing a link to cancer.
In both the building and food industry, materials labeled as styrofoam are often used interchangeably for different purposes, from disposable containers to safe drink cups.
However, health and safety concerns linger. This article discusses in detail whether microwaving styrofoam is safe and provides tips for heating food in containers made of this material.

What is Styrofoam?
Styrofoam, also known as EPS foam, is widely used across different industries. In construction, it’s used to keep things warm or cool. In the food and drink industry, you’ll find it in things like coffee cups and takeout containers because it’s light, inexpensive, and keeps food warm.
But some places, like Seattle and San Francisco, have stopped using it because it’s hard to break down and can hurt marine animals. It’s made from styrene, which can be harmful to humans too.
Is Styrofoam Safe for Food Storage?
Food containers made of polystyrene, commonly known as styrofoam, are widely used for storing hot and cold items.
They are considered safe by the U.S. Food and Drug Administration (FDA) for storing leftovers in the refrigerator.
These containers can be resealed to prevent leaks and contamination. One primary concern is to prevent air from entering the container, which could lead to food spoilage.

Is it safe to microwave Styrofoam?
Microwaving Styrofoam containers raise safety concerns. The FDA regulates plastic and polystyrene products, including EPS foam, commonly found in plates and cups. While FDA-approved products display a microwave safety label, research suggests potential hazards.
When heated, foam may leak or migrate harmful substances into food. Several studies have explored links between styrene, a compound in Styrofoam, and cancer. The CDC notes high levels of styrene exposure can affect the nervous system and classify it as a carcinogen.
Long-term exposure to styrene presents an association with various cancers, as indicated by human studies and occupational data.
For instance, a 2017 study suggested a higher risk of myeloid leukemia and Hodgkin lymphoma, while a 2018 study found an association with acute myeloid leukemia.
Additionally, a 2019 study linked exposure to increased mortality from non-Hodgkin lymphoma, pancreatic, and esophageal cancer. A systematic review calls for further research to understand the connection fully.
Factors Influencing Safety
Several factors influence the safety of microwaving Styrofoam:
- The type of container, temperatures, and length of microwave exposure are crucial.
- Storage conditions and food content also play roles.
- Microwaving Styrofoam can crack its structural integrity, leading to leakage and burns.
- Hot foods, in particular, may exacerbate substance transfer.
- Personal experience and expertise suggest cautiousness, opting for alternative containers when possible.
- While FDA-approved products may seem safer, it’s prudent to minimize microwave use with Styrofoam to mitigate potential risks.

Is It “Bad” to Put Styrofoam in the Microwave?
Styrofoam
Not all foam is the same, so it might not be so bad to use Styrofoam in the microwave sometimes, but you need to be careful. First, learn about the differences between the two kinds of foam containers you can buy.
Traditional Styrofoam
Styrofoam, a material commonly used for packaging, isn’t microwave-safe. When exposed to high temperatures, it can melt or break down, causing visible damage. This foam releases toxic chemicals, including styrene, which can leach into food.
Styrene is classified as a carcinogen, posing a threat to health and the reproductive system. In my experience, I’ve witnessed the importance of avoiding microwaving Styrofoam due to its potential risks.
Microwave-safe Styrofoam
While less common, some Styrofoam types meet FDA requirements for being microwave-safe. These alternative materials are constructed to be safer and contain lower levels of hazardous chemical compounds. Their stability when heated makes them suitable for packaging. Look for a clear label indicating microwave safety before use.
However, it’s crucial to play it safe and inspect for visible signs of damage before microwaving. If you notice any cracks or damage, discard the container to avoid potential leakage of foam into food. In my experience, it’s best to only use microwave-safe Styrofoam containers once to ensure safety.
How to Reheat Food Safely?
When reheating food, whether on the stove, oven, or microwave, it’s essential to follow general food safety guidelines. In the microwave, place food on a microwave-safe plate or bowl and cover it with a damp paper towel to prevent splattering.
For conventional oven reheating, use an oven-safe container and cover it with foil. On the stove, use a skillet or saucepan, adding a bit of water and covering it with a lid. This method works well for pizza, soups, stews, and sauces.
Don’t forget to check the internal temperature of the food before reheating. If your appliance shows signs of failure, consider reaching out to Mr. Appliance, your local appliance repair expert, for speedy service. You can schedule a service online or by calling their team.

Can you microwave styrofoam for 1 minute?
Microwaving styrofoam is generally not recommended. Here’s why:
- Potential for Melting or Warping: Styrofoam, which is a type of polystyrene, can melt or warp when exposed to high temperatures. A microwave can generate enough heat to cause this, especially if the container is empty or contains only a small amount of food.
- Chemical Leaching: When heated, styrofoam can release harmful chemicals into the food or drink it contains. These chemicals, such as styrene, are not safe for consumption and can pose health risks.
- Fire Hazard: In some cases, microwaving styrofoam can pose a fire hazard, particularly if the styrofoam is thin or contains any metal elements.
If you need to reheat food in the microwave, it’s safer to transfer it to a microwave-safe container made of glass, ceramic, or microwave-safe plastic. Always check the packaging of any container to ensure it’s labeled as microwave-safe before using it in the microwave.
