Food Security Research:The Race to Protect the U.S. Consumer
A New Way of Thinking • Dealing with intentional contamination requires consideration of • New agents • New routes of introduction
Food Security Challenge • Has required FDA to rapidly enhance its capabilities • At the core is FDA’s strong science base Food Security Enhancements ` Sound Science Food Safety Programs
Four Primary Food Security Research Needs • Knowledge of Agents • Oral pathogenicity and toxicity • Most information available is via inhalational route of exposure • Ingestion can increase or decrease potential toxicity/pathogenicity • Matrix effects largely unknown • Behavior in foods
Four Primary Food Security Research Needs • Prevention, “Shields” • Inactivation - neutralization technologies • Security technologies • In-line sensors
Four Primary Food Security Research Needs • Response and Recovery • Laboratory support • Rapid response research team • Facility clean-up
Four Primary Food Security Research Needs • Detection Methodology • Deployable, rapid field tests • Laboratory-based screening tests • Laboratory-based confirmatory tests • Forensics • Technology transfer • Methods Validation

$5M Supplement • Provided us with additional funds to get through the next lap of the race to protect the food supply
CFSAN Research Program • Within weeks of the tragedy of 9/11, CFSAN redirected 30% of its intramural research program and most of its extramural program to food security
“Foods” Research Program • Center for Food Safety and Applied Nutrition • Center for Veterinary Medicine • Feed Safety • Animal Health/Protection • Office of Regulatory Affairs • Detection method adaptation • Methods validation • FERN • National Center for Toxicological Research
“Foods” Research Program • Center for Food Safety and Applied Nutrition • Methods development • Agent characterization • Pathogencity/toxicity • Behavior in foods • Intervention technologies • Toxicity/Pathogenicity • Attempted to enhance food safety while advancing food security
“Foods” Research Program • Leverage research performed by medical, agricultural, and defense research agencies and the academic community • DHHS NIH and CDC • USDA ARS and CREES • DOD
Meeting Critical Laboratory Infrastructure Needs • Training of research to work with non-traditional agents • Upgrading of laboratory security • Upgrading of critical instrumentation • Renovation of laboratories to perform BL-3 level research • Compliance with CDC and APHIS Select Agent Regulation
CFSAN Microbiology Laboratories • First FDA laboratory to join LRN • Developed and disseminated methods for non-traditional pathogens in foods • Trained LRN and FERN members in analysis of foods • Evaluation of methods in foods
Evaluation of Detection Methods • Kits developed for clinical and microbiological samples often do not work in foods • Examining rapid methods for non-traditional agents for applicability
Microbial Forensics • Take advantage of the evolution and genetics of enteric bacteria to be able to uniquely fingerprint individual strains • Cooperating with the FBI, CIA, DHS, and DTRA
Microbial Forensics • Single nucleotide polymorphisms (SNPs) • DNA sequence based • Assigns unknowns into established clusters • Reveals “siblings”
