6. Description of content:  The Pest Management Regulatory Agency (PMRA) of Health 
Canada has recently approved an application to  amend the registration of clopyralid in 
order to allow its use for the control of broadleaf weeds and Canada thistle in timothy grass 
for forage and hay production as a post-emergent treatment. This proposed regulatory 
amendment would establish Maximum Residue Limits (MRLs) for residues of clopyralid 
in eggs, in fat, kidney, meat and meat by-products of cattle, goats, hogs, horses, poultry and 
sheep, and in milk to cover residues in f ood derived from animals fed with crops treated 
with clopyralid.  
After the review of all available data, the PMRA has determined that MRLs for clopyralid 
of 0.36 p.p.m. in kidney of cattle, goats, horses and sheep, 0.2 p.p.m. in kidney of poultry, 
0.05 p.p.m. in eggs, fat, meat and meat by-products of cattle, goats, hogs, horses, poultry and sheep, and in kidney of hogs, and 0.01 p.p.m. in milk would not pose an unacceptable 
health risk to the public. This proposed regulatory amendment would also amend the 
chemical name of clopyralid in order to  comply with international nomenclature 
conventions.
