from different countries are difficult for the FDA to oversee, leading to redundant inspections and conformity assessments. The unbundled supply chain is a logistical and regulatory problem for the FDA; it is also a failure from the trade perspective because lack of cooperation hinders free trade. Promoting regulatory cooperation and convergence in this context can help advance both U.S. trade and regulatory objectives.
U.S. bilateral and regional trade agreements can establish the structures and incentives necessary to develop and adopt common standards, policies, and assessment procedures for emerging or persistent food and drug regulatory challenges. The WTO SPS and Technical Barries to Trade (TBT) committees convene officials from 157 member countries to discuss regulations, standards, testing, and certification procedures in connection with food and drugs. The mandates of these committees include sharing information, promoting the adoption of international standards, and providing technical assistance to developing country members.,7,8 These committees provide potentially useful venues for building consensus for common regulatory approaches on difficult food and drug safety challenges.
The FDA should work harder to make the adoption of international food and drug safety standards a priority in the United States. The consistent use of standards in the U.S. market could motivate trading partners to do the same (Roberts and Josling, 2011). Even where the FDA cannot adopt an international food safety standard, it should work with other industrialized countries to streamline the means by which low- and middle-income countries can demonstrate conformity or comparability (Horton and Wright, 2008). The USTR should work with the FDA to use trade negotiations and forums such as the WTO TBT and SPS committees to promote the adoption of international, risk-based, commodity-specific performance standards for food and medical products.
EXPANDING ONE-UP, ONE-BACK TRACK AND TRACE
Counterterrorism requires that food companies be able to identify the immediate previous and immediate subsequent recipient of all the products in their supply chains (Gessner et al., 2007). This is called one-up, one-back traceability. The committee recognizes that expanding the
