Punnets of sliced white and brown mushrooms are being recalled from across the country due to the potential presence of large pieces of white plastic.
Food Standards Australia and New Zealand (FSANZ) says 200 gram, 375g and 500g punnets with best before or use by dates up to and including July 19, 2018 are affected.
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.
FSANZ says there is a potential hazard for people if plastic pieces are swallowed.
The mushrooms were manufactured by Costa Group, Australia's largest supplier of pre-packed mushrooms.
Costa 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."
It said its sliced mushrooms sold in plastic bags were not affected by the alert.
The affected products are:
FSANZ says only products with the relevant vendor number displayed on the punnet label are affected:
| Brand | Vendor number |
| Woolworths brand | 30274 |
| Coles brand | 922646 |
| Karidale (ALDI brand) | VN 01102 |
| Costa Mushrooms | All |
FSANZ says anyone who has purchased an affected punnet of mushrooms should return them to the store of purchase for a full refund.
Earlier this week FSANZ issued a recall for a number of brands of frozen vegetables sold in Aldi, Woolworths and IGA stores across the country over fears of potential contamination by deadly listeria bacteria.
