Contaminated loads

CBH is committed to quality assurance and food safety across the supply chain. We implement and maintain accreditations for ISO9001 (Quality Management System) and HACCP Codex (Food Safety).

Deliveries found to be contaminated will not be accepted at CBH sites, and where the contamination is found at the discharge point, the grain will be returned to the grower. If a load containing contaminants is knowingly delivered, then the grower will be charged under the provisions of the Bulk Handling Act 1967 (WA). We will issue contaminated load charges post-harvest to recover the cost of managing contaminated loads delivered or tendered for delivery.

Loads rejected for contaminants must not be re-tendered or blended for later delivery.

Contaminants classification

  • Level One contaminants

    Level One contaminants cannot be removed and constitute a significant food safety or quality risk. These include, but are not limited to:

    • Chemical residues. See more information on Chemical Residue Management
    • Fertiliser
    • Ball smut (wheat)
    • Pickled grain
    • Dyed grain
    • Tainted grain (including eucalyptus)
    • Dryacide treated grain
    • Glass/hard plastics.

    Delivery of a Level One contaminant automatically stops all future deliveries until an on-farm visit and investigation has been conducted by CBH and the grower/deliverer has been cleared to recommence deliveries. Detection of Level One contaminants will incur contaminated load delivery charges.

  • Level Two contaminants

    Level Two contaminants pose a food safety or processing hazard and can have a significant impact on the integrity of the supply chain. These include, but are not limited to:

    • Animal residue or excreta
    • Musty grains (oats, barley)
    • Live grain insects
    • Stock feed pellets

    Detection of Level Two contaminants will incur contaminated load delivery charges.

  • Level Three contaminants

    Level Three contaminants present a food safety or processing risk and can be managed on-farm. These include, but are not limited to:

    • Coriander
    • Declared weeds
    • Crow garlic
    • Sticks
    • Metal

    Level Three contaminants will not incur a charge. However, loads with Level Three contaminants detected will be rejected for delivery.
