BELTSVILLE, Md.New research from USDAs Agricultural Research Service reveals that essential oils in orange peel and pulp have the ability to kill E. coli O157:H7 and Salmonella in the intestinal tract of sheep. The second phase of the study examines whether the natural byproducts can be used as a potential feed ingredient in beef cattle.
According to the researchers, their results indicate that citrus products included in ruminant rations decreased ruminal populations of E. coli O157:H7 and Salmonella Typhimurium without causing a significant change in fermentation end products. Based on the data, it appears that orange pulp provides an antipathogenic activity in a vehicle that is amenable to current production practices, is palatable to the consumer as a "green" solution, is economically feasible, and is available to the producer currently.
