6. Description of content:   
Under authority of the Pest Control Products Act , the Pest Management Regulatory Agency 
(PMRA) of Health Canada has approved an a pplication for the registration of the pest 
control product (pesticide) topramezone as a herbicide for the control of  a variety of weeds 
in field corn grain as a post-emergent treatment.  
This proposed regulatory amendment would establish Maximum Residue Limits (MRLs) 
under the Food and Drugs Act  for residues of topramezone re sulting from this use in field 
corn grain, in order to permit the sale of food containing these residues.  This proposed 
amendment would also establish MRLs in fat, meat and meat by-products of cattle, goats, 
hogs, horses and sheep, in liver of cattle, goats, horses and sheep, and in milk to cover residues in food derived from animals fed with crops treated with topramezone.  
After the review of all available data, the PMRA has determined that MRLs for 
topramezone of 0.15 parts per million (p.p.m.)  in liver of cattle, goats, horses and sheep; 
0.05 p.p.m. in fat and meat by-products of cattle, goats, hogs, horses and sheep; and 0.01 
p.p.m. in field corn grain, meat of cattle , goats, hogs, horses and sheep, and milk would not 
pose an unacceptable health risk to the public.
