Microwaving with Plastic: A Guide for Safe Food Heating and Storage
Plastic containers and bags offer convenience in our kitchens, but it’s crucial to understand which ones are safe for heating food in the microwave. Using the wrong type of plastic can leach harmful chemicals into your food.
Microwavable Plastics:
- Look for the microwave-safe symbol on the container. This usually consists of wavy lines inside a rectangle.
- Opt for containers made from polypropylene (PP) or high-density polyethylene (HDPE). These plastics are generally considered safe for microwave use.
Non-Microwavable Plastics:
Avoid containers with no microwave-safe symbol or those labeled “PET” or “PS.” These can melt or warp when heated, releasing potentially toxic chemicals.
- Steer clear of thin, flimsy plastics, as they may not withstand high temperatures.
- Never microwave plastic bags, even if they’re labeled for food storage. They can easily melt and contaminate your food.
- Dishwasher Safety and Regulations:
The safety of plastics in the dishwasher can differ depending on the type of plastic.
- Look for the dishwasher-safe symbol on the container.
- Even dishwasher-safe plastics may degrade over time, potentially leaching chemicals. Consider replacing them periodically, especially if they become warped or scratched.
The Role of Regulations:
- Regulatory agencies like the U.S. Food and Drug Administration (FDA) set guidelines for the safety of food-contact plastics.
- These guidelines address factors like migration of chemicals from plastic containers into food.
- Staying informed about the latest regulations can help you make informed choices about the plastics you use in your kitchen.
Safety Reminder for Parents:
- When packing lunches or snacks for your kids, prioritize safety over convenience.
- Use microwave-safe containers whenever possible and avoid plastic bags altogether.
- Teach your children about microwave safety and to never heat unknown plastic containers.
Remember:
When in doubt, throw it out! It’s better to be safe than risk exposing yourself or your family to harmful chemicals.
Choose glass or ceramic containers for ultimate microwave safety and reusability.
By following these tips, you can ensure safe and healthy microwave practices for yourself and your family.
Safety First: The AAP emphasizes prioritizing safety in all aspects of child care, including food preparation and storage.
Microwaving with Caution: While the AAP doesn’t have an official stance on microwaving, they likely recommend caution, especially when reheating formula or breast milk. They might advise using alternative methods whenever possible to avoid potential hot spots.
Reusable Containers: The AAP promotes environmentally friendly practices, and reusable containers made from glass or stainless steel align with that goal.
Parental Guidance: The AAP stresses the importance of parental involvement in ensuring children’s safety. Educating kids about safe food handling practices is crucial.

There are several regulations regarding labelling for safe use of plastics in the US, enforced by different agencies depending on the context:
Microwavable Labeling: The Federal Drug Administration (FDA) doesn’t mandate a specific symbol for microwavable plastics. However, manufacturers are required to ensure their labels don’t mislead consumers. This often involves using the microwave-safe symbol (wavy lines in a rectangle) but other clear indications are acceptable.
Plastic Type Identification: The FDA does require plastic containers to have a recycling symbol with a number inside (1-7) indicating the type of plastic. This helps identify materials generally considered safe for microwaving (PP – Polypropylene #5, HDPE – High-Density Polyethylene #2)
Dishwasher Safety: Similar to microwaves, there’s no federally mandated symbol for dishwasher-safe plastics. However, manufacturers can use a symbol (multiple racks and water droplets) or a clear statement indicating dishwasher safety.
Overall Safety and Chemical Leaching: The FDA regulates the safety of all food-contact substances, including plastics. They establish guidelines for acceptable levels of chemicals that might migrate from containers into food. This helps ensure overall safety of the plastics used for food storage and heating.
Here’s how you can stay informed about the latest regulations:
FDA Website: The FDA website provides a wealth of information on food safety and food contact substances, including plastics. You can find resources on their website https://www.fda.gov/medical-devices/medical-device-databases/code-federal-regulations-title-21-food-and-drugs.
Look for Updates: Regulations can evolve over time. Checking the FDA website periodically or subscribing to their updates ensures you have the latest information.
By understanding these regulations and the role of agencies like the FDA, you can make informed choices about the plastic containers you use for food storage and microwaving.
