Abstract

A total of 234 randomly selected milk samples from different sources (110, 50, 34 and 40 samples) from
each of (market milk, collecting centers, bulk tank and UHT milk samples; respectively) were analyzed
for detection the quinolones residues by rapid quinolones detection strip test. Results revealed that
17.3%, 14% and 20.6% of milk samples were positive for the quinolones residues for market milk,
collecting centers and bulk tank milk samples; respectively, while not detected in UHT milk samples.
The positive milk samples were subjected to HPLC analysis for quantitative detection of enrofloxacin
residues, which were not detected in market milk and collecting centers milk samples while detected in
one sample from bulk tank milk samples. The mean value of 2.94 ppb that not exceeded the maximum
residual limit set by different international standards. Public health importance of enrofloxacin residues
was discussed
