PremiReg.Test - screening test for detection of sulfadimidine residues in eggs of laying hens.

摘要

The study investigated the presence of sulfadimidine residues in eggs after per oral administration of Sulfadimidin PG plv. sol. ad us. vet. (120 mg/hen/day) to laying hens (n=35). PremiReg.Test, a four-plate microbiological method, and HPLC were used to detect sulfadimidine residues. The positive findings of the Four-plate test (FPT) were confirmed by the results of PremiReg.Test. The absence of sulfadimidine residues was confirmed 72 h after the last sulfadimidine administration by FPT. The presence of sulfadimidine residues was detected by PremiReg.Test within 8 days and by the FPT within 3 days after the last administration. The FPT test reported false negative results for 5 days (kappa <0.6) when compared with the results of PremiReg.Test. The study confirmed the agreement of results obtained by both PremiReg.Test and HPLC (kappa=0.6). The PermiReg.Test is an important tool for monitoring the residues of inhibitory substances in a concentrations exceeding the normal limits..
