Audit of Fumigation by third party provider

The operation of a fumigator undertaking work on behalf of the biosecurity service has to be audited by officers. This procedure is also applicable for the fumigation of commodities/goods for export.

Key points to note are that the audit should ensure that treatments are conducted as required and that action is taken to rectify any operation that is not in accordance with the 31 steps that are outlined in the previous section.

Since documentation is an important component of any audit, two forms are used, one for the fumigator (Figure 10) and the other for the auditing officer (Figure 11).
