US energy bar maker Lärabar has recalled a number of its snack bars on sale in the UK due to possible salmonella contamination.

The Food Standards Agency has issued a food alert on the company's own-brand Peanut Butter Cookie flavoured snack bar (51g) and Peanut Butter Cookie flavoured mini snack bar (21g), due to the possible presence of Salmonella Typhimurium.

No other Lärabar products or flavours are known to be affected. The company has withdrawn the affected products from sale and issued a product recall notice in the national press yesterday (21 January).

The company is urging who has bought an affected product to return it to the store for a refund.

The Peanut Butter Cookie bars have a batch code: 0807021 and best before date of 30 June 2009. The mini snack bars have a batch code: 0806202 and best before date of May 2009 and 11 November 2009.

Yesterday (21 January), US grocery giant Kroger expanded its recall of ice cream products as a result of the peanut butter salmonella scare affecting manufacturers and retailers nationwide.

The US Food and Drug Administration has confirmed that the source of the salmonella outbreak is peanut butter and peanut paste made at Peanut Corporation of America's Blakely site in Georgia.

To date, 485 people have been infected across 43 states and in Canada. Six deaths have been linked to the outbreak.
