What on Earth Does BPA-Free Actually Mean?
Last Updated: 28 March 2025
If you’ve been shopping for baby bottles, food containers, or even water bottles recently, you’ve probably noticed a little label that says “BPA-free” popping up everywhere. It’s almost become a badge of honour for plastic products. But what’s the deal with BPA? Why is everyone talking about it, and more importantly, why are we so eager to avoid it? Let’s dive into what BPA actually is, why it’s been making headlines, and what you need to know to keep your family safe from the oh-so evil BPA!
What is BPA?
BPA, or Bisphenol-A, is an industrial chemical widely used since the 1960s to manufacture strong and durable plastics. It was commonly found in products like food containers, water bottles, and baby bottles. BPA is an organic synthetic compound used to produce polycarbonate plastics, which are known for their resilience and transparency.
In addition to plastics, BPA is also found in epoxy resins. These resins are often used as liners in metal products, such as food cans, bottle tops, and water supply pipes, to prevent corrosion and maintain durability.
Why are some parents concerned by BPA?
Since the 1960s, BPA has been widely used to produce strong and durable plastics, especially for food packaging and household items. However, concerns have arisen about its ability to leach into food and beverages, particularly when these containers are exposed to heat—such as during the sterilisation of baby products like bottles and dummies.
Research indicates that prolonged or increased exposure to BPA may contribute to various health issues, raising questions about its safety in everyday products.
How could BPA impact your families health?
BPA (Bisphenol-A) is a chemical that has raised significant health concerns due to its ability to mimic the hormone estrogen. By binding to estrogen receptors in the body, BPA can disrupt essential processes such as growth, cell repair, energy regulation, fetal development, and reproduction. It may also interfere with thyroid hormone receptors, further altering critical hormonal functions.
For babies, the risks of BPA exposure are particularly alarming. When BPA leaches into milk or other liquids from bottles or containers, it acts as an artificial hormone, disrupting hormonal development. This can lead to issues such as hormonal disorders, premature puberty, childhood obesity, and even long-term health risks like breast and prostate cancer. Research also indicates that BPA exposure may affect brain development, behavior, and the prostate gland in fetuses, infants, and children.
Beyond developmental concerns, BPA has been linked to broader health issues in adults. Studies suggest that exposure may contribute to increased blood pressure, type 2 diabetes, and cardiovascular disease. The widespread use of BPA in food packaging, combined with its ability to leach into food and beverages, has made it a persistent concern for public health.
While regulatory bodies have responded differently to BPA concerns, significant steps have been taken globally. In 2012, the U.S. Food and Drug Administration (FDA) banned BPA in baby bottles and sippy cups and is continues to monitor its presence in other food containers. On the other hand, the European Union has taken stricter measures. The EU approved a ban on BPA in food contact materials like can coatings, reusable plastic bottles, and kitchenware after the European Food Safety Authority (EFSA) linked BPA to harmful effects on the immune system. Similarly, countries like China and Malaysia have implemented bans on BPA due to its hormone-disrupting properties.
BPA-free doesn’t always mean safe
Products labeled as “BPA-free” do not contain Bisphenol-A. However, some may contain alternative chemicals like Bisphenol-S (BPS) or Bisphenol-F (BPF), which have similar hormone-disrupting properties.
What are the South African Regulations on BPA?
South Africa made a significant step in addressing BPA concerns by banning its use in baby bottles. This ban was officially published in the Government Gazette on October 21, 2013, and took immediate effect. South Africa was the first African country to implement such a ban, joining nations like Canada, Denmark, France, China, Malaysia, Colombia, and Brazil, which have already prohibited BPA in baby bottles.
Fortunately, nearly all baby bottles sold in South Africa are manufactured in countries where BPA in baby bottles is banned. As a result, most bottles available locally are BPA-free, especially when purchasing from well-known, reputable brands.
However, just because they should be BPA-free doesn’t mean they always are. It’s still wise to double-check. To ensure safety, research the brand online or look for a clear “BPA-free” label on the packaging. Trusted brands often highlight this certification to provide peace of mind for consumers. And avoid buying baby bottles from unverified sources.
How do I know if a product contains BPA?
If the bottle has a number 7 and the letters PC or OTHER underneath it, replace it immediately! PC stands for “polycarbonate”. BPA is a basic constituent of polycarbonate plastic, which means it can never be “BPA free”.
If the bottle has the number 7 and a T, PA or PES underneath it, it is a BPA free plastic and is fine.
If it has a 5 and the letters PP underneath it, the bottle is made of polypropylene and is BPA free and safe.
If there is no number on the bottle at all, and it’s made of clear hard plastic, rather play it safe and replace the bottle.
Is PP (Polypropylene) free from BPS & BPF?
Yes, PP (Polypropylene) is free of Bisphenol-S (BPS) and Bisphenol-F (BPF). Polypropylene (labeled as recycling code 5) is a simple polymer that does not require the use of bisphenols during its manufacturing process. PP is resistant to heat and chemical leaching, making it a safe option for food storage and baby bottles.
How do I minimise my babies exposure to BPA ?
Minimising your baby’s exposure to BPA is crucial for their health and well-being. Here are practical steps to reduce BPA exposure:
Opt for Glass Baby Bottles and Food Storage:
Glass is naturally free of BPA and other harmful chemicals, making it a safe choice for storing milk, baby food, and liquids.
Use Porcelain or Ceramic Dishes for Baby Food:
These materials are free of BPA and other plastics, providing a safe alternative for serving meals.
Choose Silicone Baby Products:
Silicone is BPA-free, durable, and heat-resistant, making it ideal for items like teethers, bibs, and spoons.
Stick to PP (Polypropylene) Plastic:
Look for plastic products labeled with recycling code 5 (PP), which are BPA-free and considered safe for baby use.
Avoid Heating Plastic in the Microwave:
Never microwave single-use plastic utensils, containers, or cling film. Heating plastic can increase the likelihood of chemicals like BPA leaching into food.
By following these steps and being mindful of the materials you use, you can greatly reduce your baby’s exposure to BPA and create a safer environment for them.
Here’s the thing—there’s no perfect way to parent. It’s literally impossible. The stuff that was considered totally fine when you were a baby might now be flagged as unsafe, and that’s just how it goes as we keep learning more about the products we use. The good news? Most of the heavy lifting has already been done for you. BPA has been removed from nearly all baby products, so you don’t need to lose sleep over it.And if your baby has been exposed to BPA, there is absolutely no need to panic. Just stop using that product, toss it in the bin, and move on. BPA is only harmful with prolonged exposure, and your baby will likely be just fine. No need to rush them to the hospital!
Our advice? Don’t sweat the small stuff. BPA exposure isn’t a death sentence, and stressing over every little thing isn’t worth your energy. Just stay aware, make informed choices, and if you’re unsure, give it a quick Google. At the end of the day, you’re doing your best, and that’s what matters most.
