Sulfonamides (formerly sulphonamides), also known as sulfa (sulpha) drugs, are synthetic antimicrobial agents. They were widely used in food-producing animals to treat bacterial diseases because of their relatively low cost and ease of administration.

There are five compounds in the sulfonamides group approved for use in food-producing animals in Australia: sulfadimidine, sulfadiazine, sulfadoxine, sulfaquinoxaline and sulfatroxazole.

Sulfonamides Review

Status: review completed

The APVMA reviewed the use of sulfonamide antibiotics in food-producing animals because of concerns over the potential for unacceptable residues in food.

In August 2000 the APVMA released the Sulfonamides Review Final Report (PDF, 202kb). In the report the APVMA cancelled the registration of one anticoccidial product containing sulfadimidine and established Maximum Residue Limits (MRLs) for each of the five sulfonamides. Read a full history of the review.
