Although saponins in tea seed meal have low acute oral and dermal toxicity for vertebrates, including mammals and birds (13), high concentrations of saponins are toxic to fish. However, with sensible guidelines (e.g., buffer zones around ponds and streams, and not treating saturated soils where runoff could occur), it should be possible to use a tea seed meal-based product without harming aquatic organisms.
