Antibiotic Residues in Food  
Due to their availability and low cost, antibiotics have been widely used in the dairy, livestock, poultry, aquaculture and honey production industries in various countries around the world. Some antibiotics have been prohibited for use in food animal production by a number of countries including Australia, Canada, USA and EU member states. This is due to concerns about possible carcinogenicity and mutagenicity.

Aminoglycosides. - Streptomycin, Neomycin, Dihydrostreptomycin, Apramycin, Gentamycin.
Beta lactams. - Ampicillin, Penicillin G, Amoxicillin, Cloxacillin.
Carbadox.
Chloramphenicol.
Macrolides. - Erythromycin, Tylosin, Lincomycin, Tilmicosin.
Nitrofuran metabolites. - Furazolidone (AOZ), Furaltadone (AMOZ), Nitrofurazone (SEM), Nitrofurantoin (AH).
Nitrofuran parents. - Nitrofurantoin, Furazolidone, Furaltadone, 5-Nitro-2-Furaldehyde.
Oxolinic acid.

Sulphonamides. - Sulfamethazine (SMZ), Sulfathiazole (STZ), Sulfamerazine (SMR), Sulfadoxin (SDX),Sulfaquinoxaline Sodium Salt (SQX), Sulfameter (SMT), Sulfafurazol (SFZ), Sulfadiazine (SDZ), Sulfapyridine (SPY), Sulfamethizole (SMZL), Sulfaphenazole (SPZ), Sulfamonomethoxine (SMM), Sulfanilamide (SNL), Sulfamethoxypyridazine (SMP), Sulfisoxazole (SIZ), Sulfachloropyridazine (SCP) Sulfadimethoxine.
