Ninety-nine eggs were received for this study through collaboration with the ACBPS and the DEWHA. Sixty-two eggs were received from the ACBPS after being autoclaved for 30 min at 121 °C (∼15 psi), as per the Australian Quarantine and Inspection Service (AQIS) requirements. Thirty-seven eggs were received from DEWHA, which had not been autoclaved. All samples received were stored in our secure and quarantine approved facility at Murdoch University. Samples in this study have been stripped of case details as they have been, or are being, used in legal proceedings.
