The Food and Drug Administration (FDA) has issued a request for comments, scientific data and information to use in risk assessment of human salmonellosis associated with the consumption of tree nuts, including almonds, cashews, pistachios, pine nuts, Brazil nuts, macadamia nuts, and walnuts.

The risk assessment seeks to quantify the public health risk associated with eating tree nuts potentially contaminated with Salmonella and evaluate the impact of interventions to prevent contamination with the bacterium or to reduce contamination levels. FDA said an assessment is necessary in light of “outbreaks of human salmonellosis linked to tree nuts during the past decade, by product recalls, and by Salmonella isolation from tree nuts during surveys.” Comments will be accepted until October 16, 2013. See Federal Register, July 18, 2013.
