Analyzing 42 specimens taken from pork, liver, kidney, we<br /> found that the average residual antibiotic rate was 23.80%), in which the highest was found in the<br /> sample of liver (35.71%)) and the lowest was in the sample of pork (7.14%)). The pig fed by the<br /> industrial food had a higher rate of residual antibiotics than the pig fed by semi-industrial food<br /> (38.09%) and 9.25%), respectively). The specimen rate of residual Oxytetraxycline of 19.04%) was<br /> higher than the residual Tetracycline specimens and the residual Oxytetraxycline + Tetracycline<br /> specimens (2.38%) and 4.76%), respectively). The amount of residual antibiotics in pork and kidney<br /> specimens was in the permitted standard. However, the amount of residual antibiotics in liver<br /> specimens was 1.05 - 5.65 times higher than the standard of JECFA and this was not safe for<br /> consumers.<br /> Key words: knowledge, attitude, practice, resident antibiotics, pork<br /> <br /> <br /> <br /> <br /> KIEN THU'C, THUC HANH CUA NGUCII T R U C TIEP CHE BIEN<br /> THtrC AN DUCiNG PHO TAI THANH PHO YEN BAI NAM 2009<br /> <br /> Loc Thi Mai' vd Cong sw<br /> <br /> Mgt cugc dieu tra cat ngang dugc thuc hien tren 224 ngudi tai cac xa, phudng cua thanh pho Yen<br /> Bai ve kien thiic, thuc hanh ciia ngudi true tiep che bien thiic an dudng phd (TADP).
