US nut firm Diamond Foods has recalled its Emerald in-shell pistachios in the wake of the pistachio salmonella scare.

The company yesterday (8 April) issued the recall of the product, which, it claimed, was in “very limited distribution”.

Diamond said it had sourced 400 cases from Setton Pistachio of Terra Bella, the California-based firm at the centre of the latest food scare to hit the US.

The company said it had received no reports of illness related to the recalled line, which has a UPOC code of 1030068389 and best-before dates of 30 January, 2010 to 10 February, 2010.

Earlier this week, the US Food and Drug Administration said an inspection had indicated salmonella was present in “critical areas” of the Setton Pistachio of Terra Bella facility in California.

The FDA said the investigation had found the “potential for cross-contamination between raw and roasted peanuts”.

Once Setton heard of the inspection’s findings, the company expanded its recall of pistachios processed at the plant.
