Whole Foods Market has become the latest US company to be caught up in the peanut butter salmonella outbreak with the recall of a line from stores in four states.

The natural and organic retailer has pulled its Carob Energee Nuggets from stores in California, Oregon, Washington, and Nevada due to possible contamination with salmonella.

Whole Foods said on Friday (23 January) that it had taken the action after Peanut Corporation of America (PCA), the bulk peanut butter supplier at the heart of the scandal, issued a recall of the peanut butter used to make the retailer's product.

No illnesses have been reported to date in connection with the problem, Whole Foods said.

The company is urging anyone who has purchased the product to return them to the store for a refund.

Some 491 people in 43 US states and one person in Canada have fallen ill following the salmonella outbreak.

Seven deaths have also been linked to the outbreak, which has been traced back to a plant in Georgia owned by PCA.

Over 125 products have been recalled in the US peanut butter salmonella food scare, with goods ranging from crackers to ice cream.

PCA has supplied over 70 companies and the likes of food manufacturers General Mills and Ralcorp Holdings and retailers Kroger and Safeway have recalled products made with ingredients from the firm.
