Long-term safety was inferred through a 90-day subchronic toxicology study using adult rats. Dose levels were selected with expected human intake levels of NFT (120\u00a0mg\/kg\/day), with an acceptable safety factor, for preclinical safety and tolerability. Sprague Dawley rats were fed diets targeting dietary intakes (doses) of 0, 125, 350, or 700\u00a0mg\/kg\/day of BPE for 90\u00a0days, an NFT dose level equivalent to 68, 190, and 380\u00a0mg\/kg\/day.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In vitro Ames test up to 5000\u00a0\u00b5g\/plate with and without S9 metabolic activation showed no BPE-related increases in revertant colony numbers and was non-mutagenic. There were no BPE-related changes in viability, clinical signs, body weight, food consumption, and organ weights.
