Review finds no sign of health or nutrition problems from GMO livestock feed

A newly published review of the prevalence and impacts of genetically engineered (GE) feedstuffs on livestock populations has concluded that there are no signs of health or nutrition problems as a result of these feeds.

The scientists collated information from the scientific literature on the performance and health of animals fed with feedstuffs containing GE ingredients, and on the products derived from GE fed animals. The data was taken from 1983, before the introduction of GE crops in 1996, and from 2011 when there was a high level of GE animal feeds in the US. In total the data represented 100 billion animals after the introduction of GE crops.

According to the review the data “did not reveal unfavorable or perturbed trends in livestock health and productivity. No study has revealed any differences in the nutritional profile of animal products derived from GE-fed animals. Because DNA and protein are normal components of the diet that are digested, there are no detectable or reliably quantifiable traces of GE components in milk, meat, and eggs following consumption of GE feed.”
