Asbestos Contamination: How a Podcast Interview Uncovered a Shocking Discovery (2025)

A chilling revelation emerged from an Australian laboratory, where asbestos contamination in children's play sand was uncovered purely by chance. This accidental discovery, featured in a podcast, sparked a chain reaction that led to a national safety recall. But here's where it gets controversial—the lab that initially tested the sand was not even aware of the potential asbestos presence, and the findings were only shared after a lab manager disclosed them in an interview.

Josh Robertson and Michael Atkin from ABC News shed light on this story, revealing that the contaminated colored sand was tested in one lab and then sent to COHLABS in Brisbane for confirmation. During a podcast interview, Michael Shepherd, the lab's co-owner and manager, casually mentioned the asbestos contamination to Robert McAllister, a director at the Faculty of Asbestos Management of Australia and New Zealand (FAMANZ).

McAllister's quick action led to a series of events that exposed the issue. He notified NZ workplace safety authorities on November 5, who then alerted their Australian counterparts. The Brisbane lab, bound by client confidentiality, was compelled to share the positive asbestos tests.

The Australian Competition and Consumer Commission responded swiftly, announcing a national safety recall for several brands of children's sand on November 12. Schools in the ACT, Queensland, and South Australia were closed as a result. Interestingly, it was the NZ authorities who informed their Australian colleagues about the contamination, as the Australian regulators were unaware until then.

The original lab testing was not intended to detect asbestos but was part of staff training and machine testing. The ACCC clarified that they first learned about the sand products through their involvement in a working group with workplace health and safety and asbestos authorities. Once alerted, they acted promptly, leading to voluntary recalls by the suppliers.

Corey Sinclair, deputy chief executive of operations at WorkSafe NZ, corroborated McAllister's account, confirming that they were notified of the potential issue on November 6 and immediately alerted Australian authorities. The sand products, imported from China by two Victorian suppliers, were sold by major retailers, including Officeworks.

Education Colours, one of the suppliers, emphasized product safety and quality as their top priorities and pledged to cooperate with regulators. However, Shamrock Australia, the other supplier, has not provided any comments.

McAllister's discovery came at the end of the podcast interview with Shepherd, where they discussed transmission electron microscopy (TEM) and its ability to identify a rare form of asbestos called tremolite. Shepherd revealed that he had tested sand products designed for children and found asbestos in the form of tremolite, a disturbing revelation.

Shepherd was bound by client privilege and could not disclose further information, but McAllister took it upon himself to investigate. He raised the issue with an NZ WorkSafe official on November 5, who shared his concern. The gravity of the situation became clear—children were at risk in educational facilities and private homes.

Australian authorities, including NSW Education, downplayed the risks, claiming that the asbestos fibers were not in a respirable form. However, McAllister challenged this, arguing that the necessary testing to prove this had not been conducted. He emphasized the vulnerability of young children to asbestos fibers and the potential hazards of playing with the contaminated sand.

The ACCC has advised the public to immediately stop using the identified sand products, secure them in sealed bags, and dispose of them safely. This incident highlights the importance of thorough testing and the potential dangers lurking in everyday products.

And this is the part most people miss—how many other products might have similar issues that remain undiscovered? The discovery of asbestos in children's sand raises questions about the safety of other consumer goods. Should there be more stringent testing regulations to protect the public, especially vulnerable populations like children? Share your thoughts in the comments below, and let's spark a discussion on consumer safety and the role of regulators.
