Khapra beetle larvae found in Woolworths nappies have triggered an urgent biosecurity response as authorities race to contain what NSW Farmers president Xavier Martin described as "the foot-and-mouth of grains."

The pest was detected in Little One's Ultra Dry Nappy Pants (Walker Size 5, 42-pack) on September 7, with national distribution through Woolworths stores. Agriculture Minister Julie Collins said about 1,500 of 2,000 cartons have been traced, with some still in circulation.

"If these pests establish in Australia, they could cost the grain industry an estimated $15.5 billion over 20 years," said DAFF's Chief Plant Protection Officer.

Container Hitchhikers

The larvae likely arrived as "hitchhikers" in shipping containers rather than from the manufacturing facility.

DAFF's Chief Plant Protection Officer Dr Gabrielle Vivian‑Smith said Spain is not a khapra beetle country and described khapra as a hitchhiker pest that can persist in contaminated containers with minimal food.

Ontex, the importer, has suspended facility operations at Eastern Creek for checks and confirmed no evidence of introduction during production. Woolworths has removed and quarantined all affected products from shelves.

Don't Bin Those Nappies

DAFF instructs consumers who purchased the affected product:

  • Don't open or dispose of packages
  • Double-bag, seal, and freeze if possible
  • Call DAFF hotline: 1800 798 636
  • Report through the official DAFF portal

While the beetle can cause skin irritation in some people, the primary concern remains agricultural biosecurity.

Trade Implications

NSW Farmers have highlighted potential trade ramifications if khapra establishes in Australia; detection and establishment can lead trading partners to reject affected stored products and impose restrictions.

Grain Producers Australia advises a fact-guided approach, emphasizing that Australia currently remains officially khapra beetle free.

DAFF continues coordinating with state agencies, retailers, and importers to trace all potentially affected products. The national priority status means significant resources have been deployed for containment.
