Epidemiology studies

Epidemiology studies   We monitor all research on BPA and have prepared responses to some of the studies relating to epidemiology. The table below lists the studies from newest to oldest. Study Key findings/claims FSANZ response Association Between Bisphenol A Exposure and Risk of All-Cause and Cause-Specific Mortality in US Adults Bao et al. (2020) JAMA Network Open 3(8):e2011620. doi:10.1001/jamanetworkopen.2020.11620

• In a cohort study of 3883 US adults enrolled in the National Health and Nutrition Examination Survey (NHANES), higher urinary BPA levels (measured in 2003-2008) were associated with an increased risk of death from all causes during approximately 10 years of observation.
• Urinary…

Studies in experimental animals

Studies in experimental animals   We monitor all research on BPA and have prepared responses to some of the studies relating to experimental animals. The table below lists the studies from newest to oldest. Study Key findings/claims FSANZ response 'Bisphenol A affects early bovine embryo development and metabolism that is negated by an oestrogen receptor inhibitor' Choi et al (2016) science Reports, 6:29318.

• In vitro incubation of bovine embryos with BPA resulted in (i) a decreased percentage (by up to 20%) in embryos considered to be suitable for subsequent transfer into a host, and (ii) an up to 50% increase in glucose consumption rate by the embryos.

• This is an in…

Cassava and bamboo shoots

Cassava and bamboo shoots Cassava and bamboo shoots available in Australia and New Zealand are safe to eat provided you prepare them properly. These foods contain cyanogenic glycosides; chemicals that can be broken down to release hydrogen cyanide, which can be harmful to consumers. Under the Food Standards Code cassava and bamboo shoots must be labelled with (or if unpackaged accompanied by) a statement indicating they must be fully cooked (and peeled in the case of cassava) before eating. Cassava The simplest method of detoxifying cassava roots is the wetting method1:

• Peel the tubers, chop them and grind them into flour
• Mix the flour with water in a ratio of 1 part cassava flour to 1.25 parts water, by weight
• Spread the mixture of flour and water in a layer not more than 1…

Dioxins

Dioxins (February 2012) What are dioxins? Dioxins are chemicals produced when household and industrial waste is burned and as by-products from some industrial chemical processes. They persist in the environment for a long time and can get into food but assessments show the amounts are tiny so the risk to our health is minimal. Dioxins also break down in our bodies and we excrete them. Where do dioxins come from? More than 96 per cent of dioxins in the environment come from air emissions. Dioxins then fall to the ground and occur in trace amounts on soil, plant and water surfaces. In Australia, the major sources of dioxin emissions in the air are bushfires and burning agricultural stubble. Plants do not generally absorb dioxins. However, dioxins can enter the food chain when animals eat plants on which…

Fluoride in bottled water

Fluoride in bottled water (June 2016) The Food Standards Code allows between 0.6 and 1.0 milligrams of fluoride (including naturally occurring and added fluoride) per litre of bottled water. This is the same level recommended for drinking water to provide benefits for dental health. A FSANZ risk assessment (Application A588 - Final Assessment Report) found there is a history of safe use of fluoride in tap water at this level. Fluoridated bottled water (at the approved levels) is nutritionally equivalent to fluoridated tap water. Not all bottled water contains fluoride. However, all bottled water with fluoride added must be clearly labelled. Bottled water with added fluoride is safe for everyone and plain bottled water (but not…
