In April, thousands of rockmelons were left to rot in paddocks near Geraldton on the Western Australian coast, record low prices and lost markets meant they were simply not worth picking.
Grower Carol Metcalf said the rows of rotting melons were the result of the listeria outbreak on a rockmelon farm more than 3,500 kilometres away in New South Wales.
Under a new plan released this week, all rockmelon farms in Australia will be inspected and work will be undertaken on each individual farm to ensure that the highest standards are implemented and maintained.
At the time of the outbreak on February this year, the NSW Food Authority speculated that the most likely cause of the listeria outbreak was contaminated soil possibly not being properly washed off the skin of the fruit.
In addition it was thought that a weather event may have increased the listeria bacteria on the product.
But the formal investigation into the cause of the outbreak has not been completed by the NSW Food Authority and therefore the official report on the cause has still not been released.
