The question of whether our food storage containers are safe is a common concern. We want to protect our food from spoilage, but we also want to protect ourselves from harmful chemicals. Rubbermaid, a household name in food storage, has faced scrutiny regarding the presence of Bisphenol A (BPA) in its products. Let’s delve into the history, science, and current practices of Rubbermaid to understand the truth about BPA and its containers.
Understanding BPA and Its Concerns
Bisphenol A, or BPA, is an industrial chemical used to make certain plastics and resins. It’s found in polycarbonate plastics, often used for water bottles, food containers, and other consumer goods. Epoxy resins containing BPA are used to line the inside of metal products, such as food cans and bottle tops.
The concern around BPA stems from its potential to leach into food and beverages. This leaching is exacerbated by heat, repeated use, and harsh detergents. Once ingested, BPA can mimic estrogen, a natural hormone, and disrupt the endocrine system.
Studies have linked BPA exposure to a range of health problems, including:
- Reproductive issues: Infertility, early puberty, and other developmental problems.
- Cardiovascular disease: Increased risk of heart disease and high blood pressure.
- Metabolic disorders: Type 2 diabetes and obesity.
- Neurological effects: Behavioral problems in children and cognitive impairment.
While regulatory agencies like the FDA maintain that low levels of BPA exposure are safe, many consumers remain cautious and prefer BPA-free alternatives. The debate continues, with ongoing research exploring the long-term effects of even small amounts of BPA on human health. This uncertainty has driven demand for products explicitly labeled as BPA-free.
Rubbermaid’s Stance on BPA
Rubbermaid has addressed the concerns surrounding BPA. The company states that many of its food storage containers are BPA-free. This wasn’t always the case, however. Historically, some Rubbermaid products, particularly those made from polycarbonate plastic, did contain BPA.
Rubbermaid has evolved its manufacturing processes to offer a wider range of materials. Now, their product line includes containers made from polypropylene, polyethylene, and Tritan, all of which are inherently BPA-free. The specific material used will determine whether a particular Rubbermaid container contains BPA.
It’s crucial to check the product labeling or the manufacturer’s website to confirm whether a specific Rubbermaid container is BPA-free. Look for markings or descriptions that explicitly state “BPA-free” or identify the plastic as polypropylene (PP), polyethylene (PE), or Tritan.
Identifying BPA-Free Rubbermaid Containers
How can you be sure that your Rubbermaid containers are BPA-free? Here’s a breakdown:
- Check the Product Label: The easiest way is to look for a “BPA-free” label on the container itself or its packaging. This is the most reliable indicator.

Are all Rubbermaid containers BPA-free?
No, not all Rubbermaid containers are BPA-free. While Rubbermaid has transitioned to manufacturing most of its food storage containers without BPA, it’s essential to check the product labeling or packaging before purchasing. Look for labels indicating “BPA-Free” to ensure the container doesn’t contain this chemical. Older Rubbermaid containers, especially those purchased before the company’s widespread BPA removal efforts, may still contain BPA.
Rubbermaid made a commitment to remove BPA from its food storage containers, and most of their current product line reflects this change. However, it is still possible to encounter older products on store shelves or in your home that do contain BPA. The company generally states that if a product is not explicitly marked BPA-free, it may contain BPA, especially if it’s an older product.
How can I tell if my Rubbermaid container is BPA-free?
The easiest way to determine if your Rubbermaid container is BPA-free is to check the bottom of the container or its packaging for a “BPA-Free” label. This label is usually prominently displayed. You can also look for a symbol of a recycling triangle with a number inside; recycling codes 3 or 7 (with “Other” or “PC” for polycarbonate) are often associated with plastics that may contain BPA. However, the absence of these codes doesn’t definitively guarantee the absence of BPA.
If your container is older and lacks clear labeling, you can try contacting Rubbermaid’s customer service with the product’s model number (if available). They may be able to provide information about the materials used in its construction. As a general rule of thumb, if you’re unsure and concerned about BPA exposure, it’s best to replace unlabeled or older containers with newer, clearly labeled BPA-free options.
What is BPA, and why is it a concern?
BPA, or Bisphenol A, is an industrial chemical used to make certain plastics and resins. It’s primarily found in polycarbonate plastics and epoxy resins, which are used in food and beverage containers, such as water bottles, baby bottles, and the lining of canned foods. The concern surrounding BPA arises from its ability to leach into food and beverages, particularly when exposed to heat or acidic conditions.
BPA is considered an endocrine disruptor, meaning it can interfere with the body’s hormones. Studies have linked BPA exposure to various health concerns, including reproductive problems, increased risk of certain cancers, and developmental effects in children. While research is ongoing, many consumers and health organizations advocate for minimizing BPA exposure as a precautionary measure, especially for vulnerable populations like pregnant women and young children.
Are glass Rubbermaid containers also BPA-free?
Yes, Rubbermaid glass containers are inherently BPA-free. Glass is a naturally BPA-free material, so there’s no need to worry about BPA leaching from the container itself. Rubbermaid’s glass containers offer a safe alternative to plastic containers for food storage, heating, and serving.
However, it’s still essential to consider the lids or any other components that might be made of plastic. While the glass portion is undoubtedly BPA-free, make sure that the lid is also labeled as BPA-free if it is made of plastic. Rubbermaid typically uses BPA-free plastics for the lids of their glass containers, but always double-check to be certain.
Can I still use my older Rubbermaid containers even if they might contain BPA?
Whether you continue to use older Rubbermaid containers that might contain BPA is a personal decision based on your risk tolerance. If you’re concerned about potential BPA exposure, especially if you are pregnant, have young children, or are otherwise sensitive, it’s generally recommended to replace those containers with BPA-free alternatives. Minimizing exposure is the most cautious approach.
If you choose to continue using older containers, avoid using them for heating food in the microwave or storing highly acidic foods like tomatoes or citrus fruits. Heat and acidity can increase the likelihood of BPA leaching into your food. Handwashing is also preferable to dishwashing, as the high temperatures in dishwashers can also contribute to BPA release. Regularly inspect older containers for any signs of wear and tear, such as scratches or cracks, as these can also increase the potential for leaching.
What other types of plastics are used in Rubbermaid containers besides those containing BPA?
Rubbermaid utilizes various types of plastics in its container manufacturing, and many are BPA-free. Common plastics include polypropylene (PP), polyethylene (PE), and Tritan copolyester. Polypropylene is often used for lids and some containers due to its durability and heat resistance. Polyethylene is another common plastic used for various applications.
Tritan copolyester is a BPA-free plastic known for its clarity, durability, and resistance to shattering. It’s often used in reusable water bottles and some food storage containers. Rubbermaid may also use other proprietary plastic blends, always aiming to meet food safety regulations and consumer demands for BPA-free products. Always check product labels for specific material information.
Does microwaving Rubbermaid containers affect their BPA content or safety?
Microwaving Rubbermaid containers can potentially affect their safety, especially if the containers are not explicitly labeled as microwave-safe and BPA-free. Heat can cause some plastics to degrade and leach chemicals, including BPA if it is present, into the food. Even some BPA-free plastics may release other substances under high heat.
To minimize any potential risks, always use containers that are specifically labeled as microwave-safe. Look for symbols indicating microwave suitability. If you’re unsure about a container’s safety for microwave use, it’s best to transfer the food to a glass or ceramic dish before heating. This eliminates the risk of chemicals leaching from the plastic into your food.
