What is the danger associated with accidentally drinking rotenone treated water?
A. The hazard associated with such an event is very low because of the low concentration of active ingredients used in treatments and the rapid breakdown of rotenone. Estimates of oral toxicity to humans are 300 to 500 mg rotenone per kg of body weight. Thus, a 132 pound person would have to drink over 60,000 liters (15,790 gallons) of treated water at one sitting to receive a lethal dose. When a 1,000 X safety factor is included, a person could drink 14 liters of treated water per day and still be well below the most conservative safe intake level.
