Penicillin^{Table 1 - Footnote b}	0.01	0.003

Sulfonamide drugs^{Table 1 - Footnote b} ^{Table 1 - Footnote d}	0.1	0.03

Chloramphenicol	Banned substance	No WRL
5-Nitrofuran compounds	Banned substance	No WRL
Table 1 - Footnote a Abbreviations: AMRL; Administrative Maximum Residue Limit; MRL, Maximum Residue Limit; and WRL; Working Residue Level. Since oxytetracycline has an established AMRL, a WRL was not considered. Return to Table 1 - Footnote a referrer Table 1 - Footnote b Penicillin and sulfonamide drug residues are of concern due to their higher potential for causing hypersensitivity reactions in susceptible consumers. To address this concern, in case where residue levels of penicillin and sulfonamide drugs exceed five (5) times the respective WRL a Health Risk 2 classification is recommended. Return to Table 1 - Footnote b referrer Table 1 - Footnote c The MRL is established only in milk. Return to Table 1 - Footnote c referrer Table 1 - Footnote d Only refers to the sulfonamide drugs listed in the "Table of Approved Administrative Maximum Residue Limits and Maximum Residue Limits" posted on Health Canada's Web site, which includes sulfacetamide, sulfabenzamide, sulfachloropyridazine, sulfadiazine, sulfadimethoxine, sulfadoxine, sulfaethoxypyridazine, sulfaguanidine, sulfamerazine, sulfamethazine, sulfanilamide, sulfanitran, sulfapyridine, sulfaquinoxaline, and sulfathiazole.
