Lead researcher Todd Callaway with USDA's Agricultural Research Service found that dietary orange peel and pulp reduced Salmonella populations in the intestinal tract of sheep.
Callaway expects the next phase of the study to yield similar results for reducing E. coli O157:H7. This ongoing study is looking at these natural byproducts, created by making juice, as a potential feed ingredient for cattle. The citrus research is one of 13 safety studies funded by cattle farmers and ranchers in 2009.
