Eight butter products sold through major supermarkets across Australia have been urgently recalled amid fears of contamination.

Food Standards Australia announced that Devondale and Woolworths butter and butter blend products had been pulled from shelves.

Producer Saputo Dairy Australia said there were concerns about potential microbial contamination – contamination with pathogenic microorganisms such as bacteria, viruses or parasites – in the popular spreads.

The dairy spreads are sold nationwide at a host of outlets, including Woolworths, Coles, Aldi, Costco and independent supermarkets.

The affected products are:
