Abstract
Using of antibacterial effected in the animal farms without control,
this using not only for protection or treatment but also to increase the
growth rate to get much money by illegal ways. Recent studies proved that
these residues have many hazards if consumed by man now public health
authorities in different countries have established different regulation for
veterinary use of the drugs in food of animal origin.
Therefore, this study was carried out to investigate the presence of
antibacterial residues in beef meat and meat products using microbiological
inhibitory assay and effect these residues on microbial quality of meat and
meat products using microbiological examination.
PART 1:
Detection of antibacterial residues in samples of meat and meat
products:
80 samples representing (20 samples each of fresh meat, minced
meat, beef burger and fresh sausage) were collected from different shops at
Sharkia govemorate for detection of antibacterial residues using microbial
inhibition test. The results revealed that 6 samples of meat and meat
products were positive for antibacterial residues with a percentage of 7.5%.
The prevalence of residues was obtained in sausage samples, (6) 30%,
which non of antibacterial residues were detected in meat samples, burger
samples and minced meat samples.
