You’re reheating last night’s pasta in a plastic container when you notice those faded recycling symbols on the bottom. Should you be worried? Spoiler: possibly yes. What is BPA in plastic? BPA (Bisphenol A) is a chemical used to make certain plastics harder and more durable. It’s been in commercial use since the 1960s, and it’s now in everything from water bottles to receipt paper. The problem? BPA doesn’t stay put—it leaches into your food, drinks, and ultimately, your body.
Here’s what every Aussie parent and eco-conscious household needs to know.
What Is BPA in Plastic? The Science Made Simple
BPA is an industrial chemical that acts as a building block for polycarbonate plastics and epoxy resins. Think of it as the glue that makes plastic hard and clear.
You’ll find it in rigid plastic containers like some drink bottles and food storage container, the lining of tin cans, and even thermal receipt paper. The recycling code to watch for? Number 7, though not all #7 plastics contain BPA.
The real issue is that BPA is an endocrine disruptor. That means it mimics estrogen in your body and can interfere with hormones—particularly concerning for pregnant women, babies, and young children.
Why BPA Is a Problem for Your Family’s Health
Multiple studies have linked BPA exposure to health concerns including reproductive issues, developmental problems in children, increased cancer risk, and metabolic disorders like obesity and diabetes.
Australian research from the CSIRO found detectable BPA levels in the urine of most Australians tested. While regulatory bodies maintain that current exposure levels are “safe,” many experts argue we simply don’t know the long-term effects—especially for vulnerable groups.
Kids are particularly at risk because their bodies are still developing and they’re proportionally exposed to higher doses. That sippy cup or plastic lunchbox? Worth a second look.
Where BPA Hides in Your Home (You’ll Be Surprised)
Beyond the obvious plastic water bottles, BPA lurks in unexpected places:
Kitchen: Canned foods (especially tomatoes and coconut milk), plastic food containers, coffee machine parts, and even some “microwave-safe” dishes.
Bathroom: Toothbrushes with conventional plastic bristles, dental sealants, and various personal care product containers. The good news? Our bamboo toothbrushes come with BPA-free bristles, and our dental floss is completely BPA-free.
Around the house: Thermal receipts, CDs and DVDs, some electronics, and even eyeglass lenses.
Even “BPA-free” products aren’t always the solution—manufacturers often replace BPA with similar chemicals like BPS or BPF, which may have similar health effects.
How to Go BPA-Free Without Losing Your Mind
Going completely BPA-free overnight isn’t realistic (or necessary). Start with high-contact items and work your way through the house gradually.
Phase out plastic food containers: Replace them as they wear out with glass or stainless steel alternatives. Don’t microwave plastic anything, even if it says you can.
Rethink your drinks: Ditch plastic water bottles for reusable glass or stainless steel. If you buy bottled water occasionally, at least avoid leaving it in a hot car.
Check your kids’ stuff: School lunchboxes, drink bottles, and teething toys should all be BPA-free. Look for products that specifically state this on the packaging.
Handle receipts carefully: Decline receipts when you don’t need them, and never let kids play with them. Wash hands after handling thermal paper.
Pro-Tips for Busy Families Making the Switch
- Start small: Replace your most-used plastic items first (water bottle, coffee cup, main food containers)
- Read the bottom: Look for recycling codes #2 (HDPE), #4 (LDPE), or #5 (PP)—these are BPA-free
- Say no to canned: Buy tomatoes in glass jars and coconut milk in cartons when possible
- Pack your own: Skip the plastic produce bags and bring reusable mesh ones instead
- Upgrade oral care: Switch to our BPA-free dental floss and bamboo toothbrushes with BPA-free bristles
- BYOC (Bring Your Own Cup): Most Aussie cafés happily fill reusable cups—some even offer a discount
The Bottom Line on BPA
You can’t eliminate every chemical exposure, and that’s okay. The goal isn’t perfection—it’s reducing unnecessary exposure where it’s practical.
Focus on the items your family uses daily, especially anything that touches food or goes in mouths. Small swaps add up to big differences over time.
