RIDASCREEN® Sulfamethazin

General information:

Sulfonamides are widely used as feed additives, mainly for fattening of calves and pigs. Combined with inhibitors of dihydrofolate reductase such as trimethoprim, tetroxoprim, or pyrimethamine sulfonamides are also used in veterinary medicine for the treatment of intestinal infections, mastitis, pneumonitis and other (systemic) diseases. Sulfonamide residues may therefore occur in food of animal origin such as meat and milk. Particularly the transmission of the carcinogenic sulfamethazine represents a threat to human health.  The EU established a maximum residue limit (MRL) for all substances of the sulfonamide-group of 100 μg/kg (ppb) in muscle, fat, liver, kidney and milk.
