Food Standards Australia New Zealand (FSANZ) has worked closely over the last few years with other Government agencies and food regulators overseas to look into any possible risks from the plastic Bisphenol A (BPA) in baby bottles and food packaging.

 

Introduction

Food Standards Australia New Zealand (FSANZ) has worked closely over the last few years with other Government agencies and food regulators overseas to look into any possible risks from the plastic Bisphenol A (BPA) in baby bottles and food packaging. We keep a close eye on issues relating to the migration of chemicals from packaging and into food, and are aware of a number of reports claiming that chemicals in plastic containers may contaminate the food or liquid inside.

Recently, the United States Food and Drug Administration (USFDA) announced a review of the safety of BPA in baby bottles and food packaging. However, these products will remain on the market in the United States and the USFDA is not recommending that families change the use of infant formula or foods, as the benefit of a stable source of good nutrition outweighs the potential risk from BPA exposure.

FSANZ has assessed the studies that led to the USFDA decision to undertake a review and further research, and our view remains that BPA in baby bottles and food packaging in Australia and New Zealand is still safe. For example our dietary modelling shows that a 5 kg baby would need to drink around 80 bottles of formula a day every day for many years before it would get up to the safety limit.

However, given recent developments in the United States, we are working with other regulators and the food industry to review these developments and to re-examine BPA levels in Australia and New Zealand.


 

What is BPA?

BPA is an industrial chemical used as the starting material for the production of polycarbonate plastics and synthetic resins. BPA is found in items or containers that come into contact with foodstuffs such as drinking vessels, baby bottles, plastic tableware and the internal coating on tins for tinned-food.   In some circumstances, chemicals in food packaging can migrate into the food product, and vice versa, depending on the nature of the packaging and the food contained within.  


 

What are the health effects of BPA?

Bisphenol A does not cause cancer. BPA belongs to a group of substances which can act in a similar way to some hormones and, as such, are sometimes called ‘endocrine disruptors’. Some studies in laboratory animals suggest that low levels of (consumed) BPA may have an effect on the reproductive system.   Similar consequences in consumers at these low concentrations are considered unlikely because  BPA is rapidly inactivated and then excreted in the urine.


 

Are very low levels of BPA in food of a concern?

FSANZ has evaluated the safety of BPA and plasticisers in food, including that consumed by infants from baby bottles and concluded that levels of intake of BPA or plasticisers are very low and do not pose a risk t o public health for any age group.   For example, a 5 kg baby would need to consume around 80 large (240 mL) baby bottles full of infant formula a day, every day over a lifetime, before reaching the daily safety limit for Bisphenol A of 50 micrograms/kilogram bodyweight per day. This would be around fifteen to twenty times more than a baby would eat.
