A biosecurity breach has authorities on high alert and they are recalling the Buzzy branded Strawberry Mini Grow Kits.

The kits are sold by The Warehouse, including those in the Bay of Plenty, and other retail outlets.

Federated Farmers vice-president Dr William Rolleston says the kits pose an environmental risk.

He says unused kits should be returned for a refund while any resulting seed or plant material should be securely disposed of in household rubbish.

'What consumers need to look for is a strawberry seed kit with the Buzzy brand.

'These were sold through The Warehouse between September 1 and November 12.”

William says these contain imported strawberry seeds, a clay pot and compressed potting mix.

'If anyone has an unused kit, maybe intended as a gift, we're asking them to please take it back to The Warehouse.

'They will apparently get a full refund so will not be out of pocket.”

People who may have used the kit are being asked to pull seeds or germinated plants from the garden with some of the surrounding soil.

William says this should then be placed in a second plastic bag, sealed and put out with normal household rubbish.

'Whatever people do, it's vital they don't compost or try to use this material as green waste.

'The safest thing to reduce the risk of a biosecurity incursion is to bury it in a landfill.”

He says while the products are being recalled, it's also essential for MAF to start testing imported items for diseases which could've hitched a ride from China, which may pose a credible risk.

'Biosecurity underpins half of all export receipts New Zealand earns from trade and services.

'We genuinely need all Kiwis on the biosecurity first XV to keep it that way.”
