Risk Assessments: Salmonella on Tree Nuts
Risk and Safety Assessment Main Page
Salmonella contamination on tree nuts has led to outbreaks and recalls of tree nuts and tree nut products in the United States.
In support of a food safety system based on prevention, the FDA is conducting quantitative microbial risk assessments to estimate the risk of human salmonellosis arising from the consumption of almonds, pecans, pistachios and walnuts in the United States.
The objectives of the risk assessments are to
- estimate the impact of microbial reduction treatment levels on the risk of human salmonellosis arising from the consumption of tree nuts in the United States.
- estimate the impact of microbial reduction treatment levels on the risk of human salmonellosis as a result of an atypical situation in the production system.
The risk assessments for Salmonella on tree nuts provide information for FDA, the nut industry, consumers and other stakeholders to use in development of risk management strategies to reduce illness from tree nuts contaminated by Salmonella.
