Don’t even think about eating a pistachio right now. And that goes for pistachio ice cream, pistachio candy and anything else that contains the tasty little nuts.

The U.S. Food and Drug Association says to wait until a report comes back as to whether the treat is responsible for the recent spread of salmonella. The inquiry comes after last week’s notification to the FDA that it found salmonella during routine testing. The source: nuts from Setton Farms in Terra Bella, Calif., about 75 miles south of Fresno.

Setton announced a recall, Kraft removed its Back To Nature Trail Mix from store shelves, and Kroger -- a grocery chain with stores in 31 states -- recalled Private Selection shelled pistachios from its retail stores.

Ultimately, the question is what should consumers do, and our advice to consumers is that they avoid eating pistachio products and keep checking the FDA Web site for the latest information," Acheson said.

An investigation is under way into how the pistachios came to carry the bacteria. Salmonella can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems.
