FARAD – Resource for Residue Problem Avoidance

FDA Veterinarian Newsletter July/August 2003 Volume XVIII, No 4

The Food Animal Residue Avoidance Databank (FARAD) is a computer-based decision support system originally designed to provide livestock producers, extension specialists, and veterinarians with practical information on how to avoid drug, pesticide and environmental contaminant residue problems. However, FARAD also offers emergency response assistance for accidental or deliberate chemical exposures to food animals. Since 1982 the FARAD has provided emergency hotline assistance to State and Federal agencies dealing with chemical contamination in food animals.

FARAD is a collaboration between USDA, FDA, and three Universities (North Carolina State University, University of Florida, and University of California, Davis). FARAD was authorized by Congress in 1998 (Public Law 105-185). Dr. Jim Riviere, Professor, North Carolina State University, College of Veterinary Medicine says one of FARAD’s functions is “to provide withdrawal time guidance in support of extra-label drug use under AMDUCA.” Dr. Riviere adds, “They also provide such information to the FDA-supported Veterinary Antimicrobial Decision Support System (VADSS) program on Prudent Antimicrobial Use and internationally to the Commonwealth Agricultural Bureau, International (CABI), which is a global storehouse and disseminator of agricultural databases.”

FARAD personnel at the University of California, Davis and the University of Florida comb through numerous sources of residue avoidance information and extract information that will be of greatest use. These data are reviewed by residue experts to ensure accuracy and consistency, and further analysis is done by FARAD personnel at North Carolina State University to explore novel ways in which the data may be used to prevent residue problems. FARAD maintains an up-to-date computerized compilation of:

  • Current label information including withdrawal times on all drugs approved for use in food animals in the United States and on hundreds of products used in Canada, Europe and Australia.
  • Official tolerances for drugs and pesticides in tissues, eggs and milk.
  • Descriptions and sensitivities of rapid screening tests for detecting residues in tissues, eggs and milk.
  • Data on the fate of chemicals in food animals.

FARAD maintains the largest database of animal pharmacokinetic data in the world. These data describe the time-course of chemical (drugs, pesticides, environmental contaminants and toxins) depletion in the tissues and products of animals. FARAD is also sanctioned to provide these estimates to the United States Pharmacopeia-Drug Information (USP-DI) Veterinary Medicine Advisory Committee. As a cooperative multi-state program, FARAD is available nationwide to offer advice about residue avoidance.
