Yes, for the vast majority of peanut butter, the plastic jars are safe as they are made from FDA-approved, BPA-free materials.
The safety of plastic jars used for food, including peanut butter, depends heavily on the type of plastic utilized. While some plastics have raised concerns due to chemicals like bisphenol A (BPA), the industry standard for peanut butter packaging prioritizes consumer safety.
Understanding Plastic Types and Safety
Not all plastics are created equal, especially when it comes to food contact. Concerns often arise around chemicals like bisphenol A (BPA), an industrial chemical found in some polycarbonate plastics, which has been known to seep into foods and beverages. However, this is largely not the case for most peanut butter jars.
The vast majority of peanut butter is sold in jars made of polyethylene terephthalate (PET). This type of plastic is widely recognized for its safety and suitability for food packaging.
Key Characteristics of PET Plastic
- BPA-Free: PET plastics do not contain BPA, addressing a significant concern for many consumers.
- FDA-Approved: The U.S. Food and Drug Administration (FDA) has approved PET for safe food contact, signifying that it meets stringent safety standards.
- Recyclable: PET is commonly recyclable, often identified by the recycling symbol #1, making it an environmentally friendlier choice.
- Durable and Lightweight: It provides an excellent barrier against oxygen and moisture, helping to maintain the freshness and quality of peanut butter.
Here's a quick comparison of common plastic types in food packaging:
| Plastic Type | Common Use Case | BPA Status | FDA Approval for Food Contact |
|---|---|---|---|
| Polyethylene Terephthalate (PET) | Peanut butter jars, soda bottles, water bottles | BPA-Free | Yes |
| High-Density Polyethylene (HDPE) | Milk jugs, detergent bottles | BPA-Free | Yes |
| Polypropylene (PP) | Yogurt containers, medicine bottles | BPA-Free | Yes |
| Polycarbonate | Some reusable water bottles, food storage containers | May contain BPA | Yes (with specific regulations) |
Regulatory Oversight and Consumer Confidence
Regulatory bodies like the FDA play a crucial role in ensuring the safety of food packaging materials. Their approval process involves rigorous testing to confirm that substances do not migrate from the packaging into food at levels that could pose health risks.
The FDA's stance on food contact substances, including PET, provides a strong foundation for consumer confidence. They continuously review scientific data to ensure that current regulations protect public health.

Practical Tips for Consumers
While peanut butter in PET jars is safe, consumers can take a few extra steps for general food safety and plastic care:
- Check Recycling Codes: Look for the recycling symbol (usually a triangle with a number inside) on the bottom of plastic containers. A #1 indicates PET, while #7 can sometimes indicate polycarbonate or other plastics, some of which may contain BPA.
- Avoid Heating Plastics: Do not microwave plastic containers unless they are specifically labeled "microwave-safe." Heating can sometimes increase the likelihood of chemical leaching from certain plastics.
- Inspect for Damage: Avoid using plastic containers that are scratched, cracked, or discolored, as these can harbor bacteria or degrade the plastic over time.
- Follow Storage Instructions: Store peanut butter in a cool, dry place as recommended on the label to maintain freshness and product integrity.
In conclusion, you can confidently enjoy peanut butter stored in its plastic jar. The industry's widespread adoption of PET plastic, which is BPA-free and FDA-approved, ensures the safety and quality of your favorite spread.
