The safety of a refined arachidonic acid-rich oil (RAO) was evaluated for reverse mutation, chromosome aberration and gene mutation, and in a 90-day Wistar rat feeding study with in utero exposure. The results of the genotoxicity assays were all negative. The in utero phase of the 90-day study involved dietary exposure to 0.5%, 1.5% and 5% RAO and two controls diets, a standard feed low-fat diet and a high-fat diet supplemented with 5% corn oil. This exposure covered four-weeks prior to mating, through mating, gestation and lactation until offspring (F-1) weaning. A subsequent 90-day feeding study in the F, rats evaluated the same test and control diets. Statistically significant effects were seen for selected histopathology, clinical chemistry and organ weight endpoints; however, other than increased absolute and relative monocytes seen in both sexes of high-dose rats, the observations were not attributed to treatment for one or more reasons. Based on these findings, no adverse treatment-related effects for RAO were seen at up to 5% in the diet, equivalent to an overall average RAO intake of 3170 mg/kg bwt/day. These and similar findings for other refined ARA-rich oils establish a strong body of evidence for the safety of this RAO. (C) 2009 Elsevier Ltd. All rights reserved.
