In December 2024, the European Commission officially banned bisphenol A (BPA) from all food contact materials, marking a significant regulatory shift based on updated health research. This decision followed the European Food Safety Authority's (EFSA) 2023 reassessment, which dramatically lowered the safe daily intake level for BPA. The ban reflects growing scientific concern about how chemicals in food storage containers migrate into the foods and beverages we consume daily.

What Changed in the Science Behind BPA Safety?

For years, regulatory agencies relied on a tolerable daily intake (TDI) standard set in 2015, which allowed 4 micrograms per kilogram of body weight per day. In April 2023, EFSA published a comprehensive re-evaluation of BPA's safety that significantly reduced this threshold based on new toxicological data. The agency's scientists reviewed emerging studies on how BPA affects the immune system and other biological processes, concluding that previous safety margins were too generous.

Bisphenol A is a chemical used to manufacture polycarbonate plastics and epoxy resins found in food and beverage containers, water dispensers, and can linings. Even in tiny amounts, these substances can migrate from the container into food and drinks, which is why regulators assess their safety so carefully. The EFSA's stricter assessment prompted the European Commission to act, implementing the ban to protect consumers from cumulative exposure over a lifetime.

How Does BPA End Up in Your Food?

Chemical migration from food contact materials happens naturally during storage, especially when containers hold warm or acidic foods. Bisphenol A leaches from polycarbonate plastics and epoxy-lined cans at low levels, but because people use these containers repeatedly throughout their lives, exposure accumulates. The EFSA's revised risk assessment took this lifetime exposure into account, which is why the agency lowered the safe intake threshold so dramatically.

The European Union had already taken preliminary steps to restrict BPA before the full ban. In February 2018, the EU introduced stricter limits on BPA in food contact materials based on EFSA's 2015 temporary safety standard. Additionally, BPA has been banned in thermal paper receipts since January 2020, recognizing that receipts are another significant source of consumer exposure.

What About BPA-Free Alternatives and Other Bisphenols?

While the BPA ban addresses one chemical, the regulatory landscape for food storage is becoming more complex. Manufacturers have increasingly turned to alternative bisphenols, such as bisphenol S (BPS), to replace BPA in products labeled "BPA-free." However, EFSA is now evaluating whether these alternatives pose similar health risks. In April 2020, EFSA published a technical report reviewing toxicological studies on BPS and recommended further data collection on its use, occurrence, and migration into food.

The European Commission has recognized this gap and is preparing new safety guidance. EFSA is developing a scientific statement detailing the information necessary for assessing hazardous bisphenols other than BPA and their derivatives when used in food contact materials. This work is part of requirements under Commission Regulation (EU) 2024/3190 and is being developed in collaboration with the European Chemicals Agency (ECHA). The statement is expected to be published by January 2027, which will provide clearer safety standards for BPA alternatives.

Steps to Reduce Your Exposure to Chemicals in Food Storage

• Choose Glass or Stainless Steel: Glass food storage containers do not leach chemicals into food and are durable enough for repeated use, freezing, and heating. Stainless steel is another non-reactive option for certain applications.
• Avoid Heating Plastic Containers: If you use plastic storage containers, do not microwave them or place them in the dishwasher, as heat accelerates chemical migration. Transfer food to glass or ceramic dishes before reheating.
• Check Labels for Recycling Codes: Polycarbonate plastics are typically marked with recycling code 7 or labeled "PC." Avoid these for food storage, especially for items stored long-term or at warm temperatures.
• Reduce Canned Food Consumption: Epoxy resin linings in metal cans can also leach BPA and related chemicals. Fresh, frozen, or glass-packaged foods may reduce exposure compared to canned alternatives.
• Be Cautious with "BPA-Free" Labels: Until EFSA completes its assessment of alternative bisphenols, "BPA-free" does not guarantee safety from all hormone-disrupting chemicals. Glass remains the safest verified option.

What Does This Mean for Consumers and Manufacturers?

The European BPA ban will reshape the food packaging industry across the EU and potentially influence global manufacturers. Companies that produce food storage containers, beverage bottles, and food packaging will need to reformulate products or switch to alternative materials. This regulatory action sends a clear signal that chemical safety in food contact materials is a priority for European health authorities.

For consumers, the ban reinforces the importance of understanding what materials touch their food. While the European Commission's decision applies to the EU, it reflects a broader scientific consensus that BPA poses health risks at lower exposure levels than previously thought. Consumers in other regions may want to adopt similar precautions, particularly for items used by children or pregnant individuals, who are more vulnerable to chemical exposure.

The ongoing evaluation of BPA alternatives highlights a key challenge in food safety: replacing one problematic chemical often introduces another that may carry similar risks. This is why material-based solutions, such as glass and stainless steel, remain the most thoroughly tested and safest options for long-term food storage. As EFSA continues its work on alternative bisphenols through January 2027, consumers and manufacturers alike will benefit from clearer guidance on which chemicals are truly safe for food contact.
