What Does BPA-Free Mean? What the Label Promises (and What It Doesn’t)

First, What Is BPA?

BPA stands for bisphenol A. The FDA describes it as an industrial chemical used to make polycarbonate, “a hard, clear plastic,” and in epoxy resins that line some metal food and drink cans. NIEHS, the US government’s environmental health institute, adds a few more places: shatterproof windows, eyewear, water bottles, bottle tops and water supply pipes.

Why do people care about it in the kitchen? Because, as NIEHS explains, food and drinks are the main way BPA gets into our bodies. It can move into food from the coating inside cans and from polycarbonate products such as tableware, food storage containers and water bottles. How much moves into a drink may depend more on the temperature than on the age of the container, according to NIEHS.

The Catch: BPS and BPF

When BPA got a bad name, some makers switched to other bisphenols, such as bisphenol S (BPS) and bisphenol F (BPF). A product made with those can still honestly say “BPA-free.”

Are those better? Not necessarily. A 2015 systematic review in Environmental Health Perspectives, the journal of NIEHS, looked at 32 studies and concluded: “BPS and BPF are as hormonally active as BPA, and they have endocrine-disrupting effects.” All of those studies were lab and animal studies (25 in the lab, 7 in animals), so they don’t tell you what happens at the levels in your kitchen. Worth knowing: the EU’s new ban also covers “other harmful bisphenols,” not BPA alone.

What to look for instead: a maker that says the material is free of all bisphenols, not just BPA. Eastman, the company that makes Tritan plastic, says Tritan “is not only BPS-free but also free of all bisphenols.” That’s the maker’s own claim, but it’s the kind of claim to look for.

Is BPA Dangerous? Why the FDA and EFSA Assess It Differently

This is where it gets confusing, because two big food safety agencies looked at the same chemical and came to different conclusions. Here are both, in their own words:

What the EU did next: the European Commission adopted Regulation (EU) 2024/3190 (December 19, 2024), which bans BPA and other harmful bisphenols in food contact materials such as can coatings, reusable drink bottles and kitchenware. After an 18-month transition, most food contact articles made with BPA may no longer be placed on the EU market for the first time since July 20, 2026. A few exceptions, such as some can coatings and professional equipment, run into 2028 and 2029, and a correction in February 2026 (Regulation (EU) 2026/250) clarified those transition rules.

I’m not going to pick a winner here; I write about storing food, not toxicology. The practical point doesn’t depend on who’s right: BPA can migrate into food from some food contact materials, such as can coatings and polycarbonate (NIEHS). That gives you choices if you’d rather keep your exposure low.

How to Avoid BPA in Your Kitchen

These steps come from NIEHS, which offers them as a personal choice, especially for infants and children:

1. Don’t microwave polycarbonate plastic containers. NIEHS says polycarbonate can break down over time from use at high temperatures.
2. Check the recycling code, but know its limits. NIEHS says some, but not all, plastics marked with code 3 or 7 may be made with BPA. So a 7 isn’t proof of BPA, and another number isn’t proof of BPA-free.
3. Use fewer canned foods, because of the BPA-based coatings inside some cans.
4. For hot food and liquids, use glass, porcelain or stainless steel when possible.
5. Use baby bottles that are BPA free.

My tip: the simplest switch is reheating leftovers in a glass dish instead of a plastic box. Glass storage containers with oven-safe bases do both jobs, which is one reason I included a glass set in my airtight container picks.

How Can You Tell if a Container Is BPA-Free?

• Look for the words on the product or packaging: “BPA-free,” or better, “bisphenol-free.” Remember that it’s the maker’s claim, and check whether it covers the lid and seal too.
• Check the maker’s own page for the material name. Tritan, for example, is a copolyester that Eastman says contains no bisphenols.
• Don’t rely on the recycling number alone. NIEHS says only that some plastics with code 3 or 7 may be made with BPA.
• No label and no information? If you can’t find out, use it for dry food or cold food rather than for reheating (my advice).
• Glass, porcelain and stainless steel aren’t plastic at all. Lids often are, so check those too (my advice).
