The mystery of how hemp found its way into breakfast cereal imported into Australia from the United States has been solved.
The presence of the prohibited plant was discovered by the Department of Agriculture, Fisheries and Forestry (DAFF) during an inspection in May and noted in DAFF's 2012 'Failing Food Report'.
Tasmanian Liberal senator Richard Colbeck raised the mystery at a senate estimates hearing in Canberra on Monday, asking the department how the hemp managed to get into the cereal.
On Tuesday, the department responded saying the product was in fact a so-called superfood cereal, produced by US company LivingIntentions called Hemp and Greens.
'Full credit to the staff who picked up on the product,' Senator Colbeck said in a statement on Tuesday.
'We are still waiting to find out how much came in to Australia and where it ended up.'
The plant is from the same family as marijuana and contains a small amount of the active ingredient that gets marijuana users high.
Hemp is widely used for its seeds and its fibre is woven into bags, rope and other materials.
According to the LivingIntentions website the cereal is enhanced with hemp protein, spirulina, chlorella, alfalfa and dandelion greens.
