Package of tetramine-based rodenticide brought to New York by vacationers returning from a visit to China in 2002. After coming into contact with the powder, a 15-month-old child was permanently injured from tetramine intoxication. The name of this brand, Yisaoguang (roughly translated as “one fell swoop”), is a fairly common name for this rodenticide in the PRC. It is also illegal.
