Viterraâ€™s harvest receival standards reflect industry codes of practice and are based on the industry standards set by Grain Trade Australia (GTA), the Australian Oilseeds Federation (AOF) and Pulse Australia. Industry conducts annual reviews of these standards and implements changes where appropriate.
For 2017/18 season various definitions have been revised for greater clarity. References to the cause of grain defects have been replaced with reference to the visual effect. Some quality parameters have been amended to better reflect customer requirements.
From time to time, Viterra will offer additional grade segregations that reflect particular customer specifications and may be for specific sites only.
Glyphosate use on barley
For each load of barley, growers will be required to use the Delivery Advice and Declaration Form to declare any application of glyphosate.
The Australian Pesticides and Veterinary Medicines Authority (APVMA) approved a permit that allows the use of glyphosate on barley (except malting barley) from 2 November 2016. If glyphosate is applied to malting varieties, the highest grade achievable is Feed Barley.
The permit is restricted to two Nufarm glyphosate products (Weedmaster DST and Weedmaster Argo). Under the permit, only one application of glyphosate can be made to the crop and a seven-day withholding period applies until harvesting can commence.
Viterra has modified its receival process for barley to reflect growers’ use of glyphosate while still protecting Australia’s market access.
For each load of canola, growers will be required to declare on the Delivery Advice and Declaration Form, that none of the canola in the load is a genetically modified variety. This declaration replaces the separate declaration form required in previous years.
As South Australia has a moratorium on GM canola, Viterra only offers non-GM segregations and can only accept varieties of canola from the Australian Oilseeds Federation (AOF) approved list for non-GM varieties.
As part of the quality testing program, Viterra collects samples from all grower loads of canola delivered to site for GM and chemical residue testing. This is essential to ensure that canola quality meets the expectations of customers as well as state and federal legislation.
Varietal identification program
Each variety has different physical quality, processing performance and end-product quality for customers and end-users.
Viterra has a varietal identification program where grower load samples will be randomly selected at sites across the Viterra network and tested to ensure varietal declarations have been correctly recorded.
This information is forwarded to relevant industry research groups and is used to establish appropriate codes of practice for the delivery of grain.
Chemical Residue Testing
Viterra subscribes to the National Residue Survey (NRS) – a crucial part of the Australian system for managing risks of chemical residues in Australian food products. To support this program, during harvest Viterra conducts chemical residue testing on composite partition samples. Viterra may also collect individual grower load samples for chemical residue traceability.
Commodity classification transfer procedure
The commodity classification transfer procedure allows for a load classified at one site to be received at a second site while retaining its original classification (subject to nil tolerance contaminants or defects).
This transfer procedure applies when a commodity is presented to a site but the load is classified as a grade not being received at the site. A transfer is then given to deliver the load to an alternate site accepting that grade.
Growers can utilise the commodity classification transfer procedure for port terminal deliveries where shipping grades are being accepted from upcountry sites. This will ensure that the load is within specification and will not be declined at port due to the lower grade not being accepted.
Loads being transferred do not have priority over other loads in the sampling queue.
If a nil tolerance contaminant or defect is found in the load at any stage of the receival process, the load will be declined.
Classification dispute resolution procedure
The classification dispute resolution procedure is used when a grower or their representative disputes the classification of their load at the point of receival.
If any test results are disputed by a grower, or their representative, whilst at the receival site, another sample will be drawn from the original Grower Load Composite (GLC) sample and retested. Only the tests which are the subject of dispute will be repeated and will override the initial results.
If results continue to be in dispute, the grower, or their representative, may elect to resubmit the load for another GLC sample to be taken and tested again, if still in dispute, a secondary sample will be drawn from this GLC sample.
If the results continue to be in dispute, the grower may elect to have the sample sent for independent analysis. Only disputes for subjective tests will be referred for independent classification.
Where a nil tolerance contaminant or defect is found, the load will be declined without further dispute settlement.
All dispute samples will be retained for future reference for three months.
Shot or Sprouted Grain Classification Procedure
The Shot or Sprouted Grain Classification Procedure is to be used if the classifier finds one shot barley kernel or one sprouted wheat kernel. The load will then be assessed using a Falling Number or Rapid Visco Analyser (RVA) machine and the result used to determine the grade.
