Are Rubbermaid Containers BPA Free? Exploring the Truth About Food Storage Safety
**Yes, most *modern* Rubbermaid containers are **BPA free. Rubbermaid phased out BPA from its food storage containers several years ago, although *older* containers manufactured before this change may still contain the chemical.
The History of BPA in Food Storage
Bisphenol A (BPA) is an industrial chemical that has been used to make certain plastics and resins since the 1950s. It’s commonly found in polycarbonate plastics, which are clear and shatter-resistant, and epoxy resins, which are used to coat the inside of metal products like food cans. BPA leaches into food and beverages, particularly when heated, raising health concerns and prompting manufacturers to seek alternatives.
Rubbermaid’s Shift to BPA-Free Materials
Rubbermaid, a household name in food storage, recognized growing consumer concerns about BPA exposure. In response, they transitioned to using BPA-free materials like polypropylene (PP) and Tritan. This move reflects a broader industry trend towards safer food storage options.
Identifying BPA-Free Rubbermaid Containers
How can you tell if your Rubbermaid container is BPA-free? Here are a few clues:
- Check the bottom of the container: Many BPA-free containers are marked with a recycling symbol number 5 (indicating polypropylene) or another resin code specifically stating it’s BPA-free. Look for labels that explicitly state “BPA-Free.”
- Consider the manufacturing date: Containers made before the transition to BPA-free materials may still contain BPA. If you’ve had a container for many years, it’s best to replace it.
- Appearance: While not foolproof, older polycarbonate containers are often harder and more brittle, whereas newer polypropylene containers tend to be more flexible.
Benefits of Using BPA-Free Food Storage
Switching to BPA-free food storage containers offers several advantages:
- Reduced Exposure to BPA: Minimizes the risk of BPA leaching into your food, potentially reducing exposure to its associated health concerns.
- Peace of Mind: Provides reassurance that you’re storing food in a safer environment, especially important for families with young children.
- Environmental Considerations: Many BPA-free plastics are also more recyclable, contributing to a more sustainable lifestyle.
Exploring Materials Used in BPA-Free Rubbermaid Containers
Rubbermaid uses a variety of BPA-free materials, each with its own properties:
- Polypropylene (PP): A durable and heat-resistant plastic.
- Tritan: A clear, shatter-resistant plastic known for its glass-like appearance.
- High-Density Polyethylene (HDPE): Often used for lids.
Potential Concerns with All Plastics
While BPA-free, it’s important to understand that all plastics can potentially leach chemicals into food under certain conditions, especially when exposed to high temperatures. Therefore:
- Avoid microwaving food in plastic containers, even if they are labeled as microwave-safe. Use glass or ceramic instead.
- Do not put very hot foods directly into plastic containers. Allow food to cool slightly before storing.
- Regularly inspect containers for damage. Discard any containers that are cracked, scratched, or discolored.
Comparison of Rubbermaid Container Materials
| Material | BPA-Free | Heat Resistance | Clarity | Durability | Common Uses |
|---|---|---|---|---|---|
| Polypropylene | Yes | Good | Opaque | Excellent | Food storage containers, lids |
| Tritan | Yes | Moderate | Very Clear | Good | Premium food storage containers, water bottles |
| Polycarbonate | No (Older) | High | Very Clear | Excellent | Older food storage containers (now phased out) |
| HDPE | Yes | Low | Opaque | Good | Lids |
Cleaning and Maintenance
Proper cleaning and maintenance can extend the life of your Rubbermaid containers:
- Wash with soap and water: Most containers are dishwasher safe (top rack recommended), but hand washing can be gentler.
- Avoid harsh chemicals or abrasive cleaners: These can damage the plastic and potentially cause chemicals to leach.
- Dry thoroughly: To prevent mold or mildew growth.
Frequently Asked Questions (FAQs)
Are all Rubbermaid containers made before a certain date unsafe?
Not necessarily. While older containers are more likely to contain BPA, it’s impossible to say definitively without knowing the specific material. The best practice is to replace older, worn containers as a precaution.
How can I tell if my Rubbermaid container is microwave-safe?
Look for the microwave-safe symbol (usually a picture of a microwave with a container inside) on the bottom of the container. However, even if microwave-safe, it’s best to use glass or ceramic for heating food to minimize any potential chemical leaching.
Does freezing food in plastic containers pose any risks?
Freezing generally slows down the rate of chemical leaching. However, extremely low temperatures can make some plastics brittle, leading to cracks. Avoid dropping frozen containers.
Can I put my Rubbermaid containers in the dishwasher?
Most Rubbermaid containers are dishwasher-safe, but it’s generally recommended to place them on the top rack to avoid direct heat from the heating element. Refer to the specific product instructions.
What are the health concerns associated with BPA exposure?
Studies have linked BPA exposure to potential health problems such as hormonal disruption, reproductive issues, and an increased risk of certain cancers.
Are there any alternatives to plastic food storage containers?
Yes! Excellent alternatives include glass containers, stainless steel containers, and reusable silicone bags.
Are Rubbermaid’s replacement lids BPA-free?
Yes, replacement lids sold today are also BPA-free, following the same standards as their containers.
Is the color of a Rubbermaid container an indicator of whether it contains BPA?
No, the color is not a reliable indicator. The presence or absence of BPA depends on the type of plastic used and the manufacturing date, not the color.
What should I do with my old Rubbermaid containers that might contain BPA?
Check your local recycling guidelines. Some recycling programs may accept certain types of plastic. If not, consider repurposing them for non-food uses or disposing of them properly.
Does heating food in the microwave in BPA-free plastic still pose a risk?
While BPA is not a concern with BPA-free plastics, other chemicals can still potentially leach when heated. It’s best to use glass or ceramic in the microwave whenever possible.
Are all Rubbermaid products besides food storage containers BPA-free?
Not necessarily. The transition to BPA-free materials primarily applies to food and beverage containers. Other Rubbermaid products, such as certain toys or outdoor items, might use different plastics. Check the labeling for specific products.
Where can I find more information about BPA and food safety?
Reliable sources of information include the U.S. Food and Drug Administration (FDA), the Environmental Protection Agency (EPA), and reputable consumer advocacy groups. Always consult trusted sources for the most up-to-date information.
