Authorities looking into the nationwide pistachio recall say they're investigating a California nut processor's sister company in New York where officials last month found cockroaches and rodent droppings.

The Food and Drug Administration said Thursday that Commack, N.Y.-based Setton International Foods Inc. shares key staff and packages food with Setton Pistachio of Terra Bella Inc., the second-largest pistachio processor in the nation,

The central California firm earlier this week recalled 2 million pounds of nuts over fears of possible salmonella contamination.

Last month, New York agricultural authorities found live and dead cockroaches and rodent droppings inside the Commack plant, which failed its state health inspection.
