Abstract:An ELISA method was developed for the determination of tetracycline,chlortetracycline,oxytetracycline
and deoxycycline residue in swine,cattle and fish tissues based on the multi—residue test kit for tetracyclines made
in our laboratory.The limit of detection was not more than 13 kg.Recoveries ranged from 47.5% to 119.4%
for swine,cattle and fish tissue sample fortified with Tetracyclines at the MRL of each tissue.The intra-and inter—
precision values were within 25% o The cut-0ff value of swine meat。swine liver,cattle meat,cattle liver and fish
meat were 49.2,138.7,52.1,124.4 and 44.1 kg respectively.
