A tolerance of 0.05 part per million is established for negligible residues of monensin in the edible tissues of cattle and goats.
A tolerance for residues of monensin in chickens, turkeys and quail is not needed.
Tolerances for total residues of combined arsenic (calculated as Arsenic) in food are established as follows:
a. Chickens and turkeys (edible tissues): (1) 0.5 part per million in uncooked muscle tissue. (2) 2 parts per million in uncooked edible by-products.
b. Chicken and turkey eggs: 0.5 part per million
c. Swine (edible tissues): (1) 2 parts per million in uncooked liver and kidney. (2) 0.5 part per million in uncooked muscle tissue and by-products other than liver and kidney.
The tolerance for residues of bacitracin from zinc bacitracin or bacitracin methylene disalicylate in uncooked edible tissues of cattle, swine, chickens, turkeys, pheasants, and quail, and in milk and eggs is 0.5 part per million
