The rockmelon farm linked with the listeria outbreak that resulted in six deaths has been cleared to supply fruit again.
Rombola Family Farms has issued a statement which confirms that the NSW Food Authority has given it approval to resume production, packing, and the sale of rockmelons.
The farm, which is based at Nericon near Griffith, has met all the requirements of the authority's clearance program, according to ABC News.
While a link between the contamination and the rockmelons was established, the farm's statement said neither the authority nor an independent microbiologist were able to identify any specific source associated with Rombola or with the farm's rockmelon washing, storage or packing facilities.
The Australian Melon Association (AMA) has expressed concerns, however, that the cause of the outbreak had not been "traced or adequality addressed".
The association's industry development manager Dianne Fullelove said growers were anxious to understand what went wrong, adding that they had not received a report on the outcomes of the Food Authority's investigation.
The farm said it will undertake mandatory testing as part of the authority's clearance program as well as voluntary testing on a daily basis.
