The GRDC is aiming to improve the quality of grain being delivered from farm through encouraging best practice, reminding farmers an appropriate post-harvest management strategy is essential to preserve grain quality during storage.

Agri-Science Queensland grain storage expert Philip Burrill said the four key factors for pest control and grain quality were hygiene, aeration cooling, monitoring and correct fumigation.

Meanwhile, WorkCover NSW urged farmers and farm workers to think about the risks associated with storing grain on-farm.

With the harvest season near completion and many farmers deciding to store grain on-farm, WorkCover Work Health and Safety Division general manager John Watson said this could introduce new risks to farmers and farm workers.

"Many farmers have turned to flat bed storage and bunkers with tarps to store excess grains from harvest while they wait for prices to increase," Mr Watson said.

"This storage method comes with inherent safety risks.

"When tarping grain in a bunker and climbing on top of the pile, take caution to avoid becoming engulfed in the grain as this can lead to suffocation.

"Also be conscious of weather conditions, because if the wind catches the tarp it can throw a farmer into the air. This occurred just last year in Victoria, with fatal consequences."

It is not just storage under the microscope, but also harvesting practices.

Sheila Payne, executive officer of Farmsafe WA Alliance, said during long shifts under pressure, growers should be mindful of the increased risk of accidents, which can cause injury to operators or damage to equipment and set harvest further back.

"Growers should practice ways of dealing with tiredness to prevent fatigue, which is a hazard in the workplace," Ms Payne said.

"Encouraging staff to do the same will promote a safety culture and could also prevent expensive damage to equipment and downtime getting it fixed."
