The review, led by UC-Davis animal scientist Alison Van Eenennaam, examined nearly 30 years of livestock-feeding studies that represent more than 100 billion animals.
“Studies have continually shown that the milk, meat and eggs derived from animals that have consumed GE feed are indistinguishable from the products derived from animals fed a non-GE diet,” Van Eenennaam said. “Therefore, proposed labeling of animal products from livestock and poultry that have eaten GE feed would require supply-chain segregation and traceability, as the products themselves would not differ in any way that could be detected.”
Food-producing animals such as cows, pigs, goats, chickens and other poultry species now consume 70 to 90 percent of all genetically engineered crops, according to the UC-Davis review. In the United States alone, 95 percent of food-producing animals consume feed that contains genetically engineered ingredients.
Sync biotech approvalsNow that a second generation of genetically engineered crops that have been optimized for livestock feed is on the horizon, there is a pressing need to internationally harmonize the regulatory framework for these products, she said. “To avoid international trade disruptions, it is critical that the regulatory approval process for genetically engineered products be established in countries importing these feeds at the same time that regulatory approvals are passed in the countries that are major exporters of animal feed,” Van Eenennaam said.
