The effects of faecally excreted ivermectin on the survival and growth of the common Korea earthworm Eisenia fetida (Savigny), have been studied in the laboratory. Cow dung was collected 1, 2, 3 and 7 days after ivermectin subcutaneous injection. The mortality of the worms provided with untreated dung was 0% whereas mortality within a week was high as 73.7%, 98.3% in dung which were excreted 1 and 2 days from dosing, respectively. The growth rate of the worms fed dung from 1 day excreted dung from cattle given ivermectin was 75% lower than that recorded on the control.
