Fumigation treatment:
All loose, bulk stock feed consignments and all meal products must be fumigated prior to or during shipment to ensure that subsequent infestation from holds, containers or other chance pest presence does not occur.

Fumigation must be with phosphine or methyl bromide at the following prescribed rates. The fumigation certificate must state the fumigant used and the rate used. Fumigation given prior to shipment must be carried out no more than 21 days prior to shipment.

Phosphine: (prior to shipment or in transit):
Fumigation can be carried out prior to shipment or may be carried out with phosphine generating products e.g. tablets, pellets, sachets or blankets introduced with the product into the sealed container or ships' hold to be effective during the journey (the ships' master must be notified).

The table below gives the rates to be used when using phosphine generating products. Three days must be added if the fumigant is surface applied in trays. One day less may be subtracted for cylinderised phosphine gas application completed prior to shipment. The fumigation certificate must state the method of application and clearly state whether the consignment was exposed to the fumigant before the voyage with the fumigant removed, or whether the application was with tablets, pellets, sachets or blankets introduced with the product into the sealed container or ships' hold to remain there for the journey.

Phosphine application is based on the internal volume of the enclosure.

• 32grm/m3 for 24 hours at 21+ degrees Celsius.
  

Note: 

Meal products in bags only may be given an increased inspection on arrival in lieu of fumigation.

If treatment is undertaken onshore exporter to provide evidence attesting to the treatment and to present to the Department of Agriculture Authorised Officer at time of inspection.
