Guinness is recalling cans of its non-alcoholic stout because of contamination fears, just two weeks after they were launched.
The brewer described the recall as “precautionary”, but said “microbiological contamination” might mean some products were unsafe.
The company urged anyone with cans of Guinness 0.0 not to drink them.
It said it was working with supermarkets and other shops to remove all of the products from the shelves.
The recall only affects customers in Great Britain, as the product was not yet on sale in Ireland or Northern Ireland.
Guinness 0.0 was only launched in supermarkets and online on 26 October.
In a statement the brand, which is owned by Diageo, apologised to customers.
“We wanted to let you know that as a precautionary measure we are recalling Guinness 0.0 in Great Britain because of a microbiological contamination which may make some cans of Guinness 0.0 unsafe to consume.
“If you have bought Guinness 0.0 do not consume it. Instead, please return the product to your point of purchase for a full refund.
“Alternatively, contact the Diageo Consumer Careline… with details of your purchase to receive a refund voucher before disposing of the product.”
On its website, the brewery also says its team is “working hard to investigate and determine the root cause” of the contamination.
The new product was created in response to what Guinness said was growing consumer demand for lower-calorie and non-alcoholic drinks.
Other Guinness products are not affected by the recall.
