The US Food and Drug Administration (FDA) has warned consumers to avoid two brands of pistachios tied to a salmonella recall.

Consumers are being urged not to eat California Prime Produce and Orange County Orchards brands of pistachios repacked by Orca Distribution West, as they may have been repackaged and sold in airports and hotels, the FDA said on Tuesday (23 June).

The companies had received and repacked pistachios recalled by Setton Pistachio of Terra Bella, which issued a nationwide recall of its products in late March after salmonella was found in some nuts.

The FDA visited Orca as part of its audit checks to follow up on Setton Pistachio's recall. The FDA found that products subject to Setton Pistachio's recall had been repacked and distributed by Orca under the California Prime Produce and Orange County Orchards brands.

Orca however, had not made a public announcement regarding the products, the FDA said.

The products were distributed to retail locations in airports and hotels nationwide. The California Prime Produce and Orange County Orchards brands of pistachios were packaged in clear 6oz flexible plastic Ziploc bags, UPC Number: 8 10826 01116 2 with sell by dates of 7/30/09 and 8/30/09.

Consumers who have purchased these products are being urged not to eat them. They can also report problems, including adverse reactions, to the FDA district office consumer complaint coordinator in their area of the country.

To date, more than 660 product entries have been included in the FDA's list of recalled products because of their association with the recall by Setton Pistachio of Terra Bella Inc.
