On Thursday 25 June, researchers behind an AUT study examining sand products containing asbestos shared some of their high-level results with the Ministry of Health and other agencies.
The results confirm that some of the recalled sand products can release asbestos fibres into the air. We recognise that the new information in this study may be concerning for the public, particularly for parents and caregivers.
The Ministry of Health reconvened a cross-agency Technical Advisory Group of scientists, doctors and environmental health experts to rapidly assess whether the study’s results materially change our understanding of the health risk posed by these products.
Since these sand products containing asbestos were identified in November last year, health authorities have been taking a precautionary approach and assuming all identified products can release fibres into the air.
The study confirms that assumption and supports our approach taken to date.
The Group has reconfirmed both that asbestos in these recalled sand products presents a potential health risk and that current health advice for households remain appropriate.
The existing health advice for households can be found on Health New Zealand’s website.
The Ministry will continue to monitor any emerging evidence and will reconvene the Group if needed.
Health risks from asbestos in sand
Exposure to asbestos does not cause any immediate health problems. Health conditions linked to asbestos develop over a long period.
When asbestos fibres are breathed in, they can become stuck in the lungs and damage the lung tissue. Over a long period of time, this can occasionally lead to conditions such as asbestosis and mesothelioma.
The risk of developing asbestos-related health conditions is linked to the nature and quantity of asbestos and the length of time a person was exposed to it.
There is no safe level of exposure and therefore we try to avoid all exposure.
However, for most people who had these products at home, the quantities involved would likely be small. That is very different to the greater risk for people who might be exposed in an occupational setting.
Actions if you have these products at home
- If you or your child has used the product, there is no need for urgent medical attention. Discuss any concerns with Healthline on 0800 611 116, who will advise if you or your child needs to see a healthcare professional for review.
- Avoid further exposure by removing the product safely. Removal advice can be found on Health New Zealand’s website.
