Brown seaweed

All biosecurity requirements must be met before Imported Food Inspection Scheme requirements apply.

Check our Biosecurity Import Conditions system (BICON) for biosecurity import conditions.

We classify imported food that presents a potential medium or high risk to public health as risk food. All risk food is listed in the Imported Food Control Order 2019.

Brown seaweed in the Phaeophyceae class is classified as risk food

This includes brown seaweed belonging to the scientific class Phyophyceae or Phaeophyceae, that is dried, fresh or frozen.

Exclusions

All other scientific classes of seaweed.

Community Protection (CP) question

You will need to answer these CP questions when lodging your full import declaration:

IFIS: Are the goods seaweed of the Phyophyceae or Phaeophyceae class (brown seaweed)? Search ‘brown seaweed’ at www.awe.gov.au for more information
IFIS: Are the goods seaweed of the Sargassum fusiforme genus and species (also known as Hijiki seaweed)?

Inspection and testing

We refer consignments of brown seaweed for analytical testing. Additional testing applies to Hijiki seaweed. During inspection, we will also conduct a visual and label assessment.

Table 1 shows the tests that will be applied and permitted results to the food type.

**Table 1, Food type, test applied and permitted result**
Food type	Test applied	Permitted result
All brown seaweed	Iodine	Maximum level 1000 mg/kg dry weight
Hijiki seaweed (Sargassum fusiforme) only	Inorganic arsenic	Maximum level 1 mg/ kg calculated at 85% hydration

Food safety risks

Food Standards Australia New Zealand (FSANZ) has given us advice about the risk of brown seaweed. This food presents a potential medium or high risk to public health for iodine. FSANZ has also advised that Hijiki seaweed presents a potential medium or high risk for inorganic arsenic.
