Chemical residue management
Role of CBH in managing chemical residues
To help maintain our reputation for supplying clean and safe grain, CBH tests for chemical residues both during and after harvest. CBH works with local industry and destination markets to understand requirements and changes in this dynamic environment.
In addition, through the National Residue Survey (NRS), DAWE conducts chemical residue testing on every shipment of grain exported from Australia. Grain buyers also conduct independent chemical residue testing on export shipments from WA.
CBH’s chemical residue testing process
Grain samples are collected in the sample shed in secure, tamper-evident packaging and sent to CBH’s Australian Grains Centre, before being tested by a National Association of Testing Authorities (NATA) accredited laboratory.
If a chemical residue is detected above the Australian MRL, the sample is re-tested by a third-party laboratory.
Outcome and discussion
If the re-tested sample contains chemicals above the relevant MRL, our Country Quality team will contact the grower to provide details of the contaminated loads. When chemical residues are detected, and the result is not disputed or stands following dispute and consultation with CBH, the following contaminated load delivery charges will apply:
- Where detections are not made in consecutive years, the charge structure restarts from the first year.
- These charges may vary if the dispute process is applied.
- Detections are measured against maximum residue limits (MRLs), with reference to the Australian MRL as set by the APVMA.
If growers would like to dispute the chemical detection in their load, they must do so within 30 days of being contacted by the CBH Country Quality team in line with CBH’s Post-harvest Dispute Process.
For queries regarding the use of chemicals on your grain, please seek expert advice from your local agronomist or chemical supplier. You can also view the relevant Australian MRL from the Australian Department of Agriculture, Water and the Environment.
