The recall of salmonella-contaminated pistachios has drawn in a number of other companies, with PepsiCo’s Frito-Lay, Kraft Foods and Kroger forced to issue consumer recalls.

After the detection of salmonella in its products, Setton Pistachio of Terra Bella, the second-largest pistachio processor in the US, ceased all distribution of processed pistachios this week. The company also issued a voluntary recall involving around one million pounds of its products.

The recall affects certain bulk roasted inshell and roasted shelled pistachios shipped on or after 1 September 2008.

As a consequence, Frito-Lay issued a recall for 1.75-ounce packages of Frito-Lay Salted Pistachios with sell-by dates between 14 July 29 December 2009. The UPC code is 0 28400 03888 1. The date is on the front of each package.

No other date codes are known to be affected.

Meanwhile, Kraft initiated a nationwide recall of Planters and Back to Nature Products containing pistachio nuts – more than 23 products in all. A full list of recalled products is available on the company’s website.

US retailer Kroger has also announced a recall of Private Selection Shelled Pistachios with the following UPC codes: 11110 73615 and 1111073615.

The FDA recommended yesterday (31 March) that consumers avoid eating pistachio products until further information is available about the scope of affected products.

The FDA and the California Department of Public Health (CDPH) are investigating the contamination, which involves multiple strains of salmonella.
