March 30, 2009 (Washington D.C.)--The FDA and the California Department of Public Health (CDPH) are investigating Salmonella contamination in pistachio products sold by Setton Pistachio of Terra Bella Inc, Calif. The company has stopped all distribution of processed pistachios and will issue a voluntary recall involving approximately 1 million pounds of its products. Because the pistachios were used as ingredients in a variety of foods, it is likely this recall will impact many products and consumers are advised to avoid all pistachios. The investigation at the company is ongoing and may lead to additional pistachio product recalls.
