Sec. 73.12  Ivermectin.\1\

    (a) Cattle affected with scabies or which just prior to movement 
were affected with or exposed to scabies may be moved interstate from a 
nonquarantined area after being treated with ivermectin under the 
supervision of an APHIS inspector or State inspector in accordance with 
the directions on the label of the drug if the following conditions are 
met:
---------------------------------------------------------------------------

    \1\ Tissue residues remain following treatment with ivermectin. 
Cattle treated with ivermectin are not allowed to be slaughtered for 
food purposes until the expiration of such period as may be required 
under the Federal Meat Inspection Act (21 U.S.C. 601 et seq.). Further, 
the animal drug regulations in 21 CFR parts 522 and 556 promulgated 
under the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 301 et seq.) 
contain limitations on the use of ivermectin and contain tolerances for 
ivermectin in edible cattle tissue. With respect to the limitations 21 
CFR part 522 provides the following: ``For subcutaneous use only. Not 
for intramuscular use. Do not treat cattle within 35 days of slaughter. 
Because a withdrawal time in milk has not been established, do not use 
in female dairy cattle of breeding age. Federal law restricts this drug 
to use by or on the order of a licensed veterinarian.''
---------------------------------------------------------------------------

    (1) Such cattle are kept physically separated for 14 days following 
treatment from all cattle not part of the group treated together with 
ivermectin (regardless of whether the cattle are moved interstate before 
the end of the 14-day period); and
    (2) If such cattle are moved interstate before the end of the 14th 
day following treatment, at the time of interstate movement they are 
accompanied by a certificate issued and signed by an APHIS inspector or 
State inspector identifying the group of cattle treated with ivermectin 
and stating the date on which the cattle were treated with ivermectin; 
and
    (3) If such cattle are moved interstate before the end of the 14th 
day following treatment, at the time of interstate movement the means of 
conveyance carrying them is placarded and the billing marked in 
accordance with Sec. 73.6.
    Note: Cattle from nonquarantined areas which are not affected with 
scabies or which just prior to movement were not affected with or 
exposed to scabies may be moved

interstate without restrictions under this part. Accordingly, cattle 
from nonquarantined areas which had been treated with ivermectin more 
than 14 days before movement interstate may be moved interstate without 
restriction under this part unless following treatment they become 
affected with scabies or just prior to movement become affected with or 
exposed to scabies.
    (b) Cattle may be moved interstate from a quarantined area after 
being treated with ivermectin under the supervision of an APHIS 
inspector or State inspector in accordance with the directions on the 
label of the drug if the following conditions are met:
    (1) Such cattle are moved interstate within 21 days following 
treatment with ivermectin; and
    (2) Such cattle are kept physically separated for 14 days following 
treatment from all cattle not part of the group treated together with 
ivermectin (regardless of whether the cattle are moved interstate before 
the end of the 14 day period); and, if such cattle are moved within the 
15- to 21-day period following treatment, they remain kept physically 
separated from all cattle not a part of the group treated together with 
ivermectin until after they are moved interstate; and
    (3) Such cattle are accompanied at the time of interstate movement 
by a certificate issued and signed by an APHIS inspector or State 
inspector identifying the group of cattle treated with ivermectin and 
stating the date on which the cattle were treated with ivermectin; and
    (4) If such cattle are moved interstate before the end of the 14 day 
period following treatment, at the time of interstate movement the means 
of conveyance carrying them is placarded and the billing marked in 
accordance with Sec. 73.6.
