Punnets of sliced white and brown mushrooms are being recalled nationwide due to potential plastic contamination from the packaging.
The recall is "due to the potential presence of large pieces of white plastic" which pose a hazard if swallowed.
The mushrooms were manufactured by pre-packed mushrooms supplier Costa Group, which said it issued the recall following the discovery of damage to plastic rollers on a packaging line at its Victorian mushroom production facility.
"As soon as the issue was detected, even though there were no reported incidents, Costa advised food safety authorities of the intention to conduct a recall, and retailers were notified to withdraw the product from sale," the company said on Facebook.
"While the probability of consumer impact is extremely low, and the large pieces of white inert plastic would be highly visible, consumers who have not used the sliced mushrooms are advised to return the product to the store of purchase to receive a full refund."
The recalled products include mushrooms sold under the Woolworths, Coles, Karidale (Aldi) and Costa Mushrooms brands in Victoria, New South Wales, Queensland, Tasmania and the ACT.
Food Standards Australia and New Zealand (FSANZ) said products affected were 200g, 375g and 500g punnets with best before or use by dates up to and including 19 July 2018.
They have been available for sale in Coles, Woolworths, Aldi and independent supermarkets and greengrocers in Victoria, New South Wales, Queensland, Tasmania and the ACT.
Costa said its sliced mushrooms sold in plastic bags were not affected by the alert.
The recall is being conducted by Mushroom Exchange, a Costa group company.
