Sulfonamides provide broad-spectrum antimicrobial activity and protect against both Gram-positive and Gram-negative bacteria. In addition, they inhibit bacterial dihydropteroate synthase, a key enzyme in folate synthesis. As a result, this disruption prevents bacteria from producing essential nucleic acids and stops growth, replication, and infection progression.
Due to their strong efficacy, veterinary medicine has widely used sulfonamides to treat a range of infectious diseases in livestock. Furthermore, beekeeping practices have also applied them in apiculture to prevent and control bacterial diseases in honeybee colonies. In particular, beekeepers use them against American foulbrood and European foulbrood, both of which can significantly damage colony health and productivity.
However, concerns about antimicrobial resistance have led regulators to impose stricter controls on their use, especially in food-producing animals. Consequently, resistant bacterial strains continue to emerge and threaten both animal and human health. Therefore, authorities now prioritise controlled and responsible use of these compounds.
Moreover, recent detections of sulfonamide residues in commercial honey have increased concern about contamination pathways. These may include environmental exposure, poor beekeeping practices, or illegal veterinary use. As a result, these findings highlight the need for strong monitoring systems and effective regulatory enforcement.
To address these risks, stakeholders must adopt an integrated and interdisciplinary approach. Specifically, regulators must combine strong legislation with advanced analytical testing methods. In this way, they can ensure honey safety, protect consumer health, and maintain confidence in apiculture products across global food supply chains.
