Carbarsone in the form of a proprietary formulation containing 33.6 w/v p ‐ureidobenzene arsonic acid was fed to turkey poults at dietary levels of up to 0.075%. There was a slightly increased mortality among the birds that had received the 0.075% level from the first day after hatching, but there was no evidence of any adverse effect upon food consumption or upon bodyweight gain among the survivors up to the time of killing at 24 weeks, and no macroscopic evidence of any organ damage. Tissue arsenic residues at 24 weeks were higher with a “zero withdrawal” period than when the Carbarsone was withdrawn 4 days before slaughter, but were still of a low order: the highest individual arsenic residue was 0.4 part/million in a sample of breast muscle from a poult that had received 0.075 part/million throughout, with a “zero withdrawal” period.
