8. 8 Cloning: Summary  No threat to human health (EFSA, FDA)  Negative impact on animal welfare  High cost, so confined to animals for breeding  Possible “no clone” product lines  Possible consumer resistance (GM parallel?). Kroger Safeway Dean Foods Wholefoods.

9. 9 FDAUSDA Regulates the safety and labelling of all food products except traditional meats, poultry and egg products. Regulates the safety and labelling of traditional meat, poultry and egg products and has a role in promoting American food products. The Washington Post, January 16 th, 2008 “We have no further safety concerns…We conclude that meat and milk from cattle, swine and goat clones are safe as food we eat every day.” “USDA has encouraged technology providers to maintain their voluntary moratorium on sending milk and meat from cloned animals into the food supply chain during this transition time.” Stephen Sundlof, Director, FDA Centre for Food Safety and Applied Nutrition Bruce I. Knight, Undersecretary of agriculture for marketing and regulatory programmes. What they say… Responsibility

14. 14 Why Traceability #1? CORN FED? CLONED?

15. 15  Consumer protection: “What you pay for is what you get”  Retailer protection: “Guarantee of authenticity of products”  Brand protection: for producer, packer, retailer  Brand enhancement: “Adds value to added value”. Why Traceability #2?

16. 16 Why DNA Traceability?  Unique animal identity (“God’s barcode”)  DNA the ONLY tamper-proof method  Independent  Traces product, not labels  Tracing clones is straight-forward  Tracing progeny of clones also possible i.e. paternity testing  Competitive in cost.
