All animals survived following oral gavage doses of 15.8, 31.6 or 63 mg/kg. Two of three died within 2 hours after ingesting 126 mg/kg and all died within 1 hour after ingesting 252 mg/kg. Using the probit model, the LD50 is approximately 120 mg/kg bw. No signs of toxicity other than death were seen in these animals. One animal from each of the three lowest dose levels was necropsied 24 hours after exposure. No visible lesions were found. The surviving animals surpassed their pre-exposure body weight by the end of the two week observation period.
