Abstract:
This study was aimed to determining antibiotic residues contamination and the presence of penicillin and oxytetracycline in dairy milk ,in River Nile state.The study depending on previous survallence had been done since 2017 by department of veterinary public health and food safety incollaboration with Sudanese standards and metrology organization (Atbara branch).This study involved analysis of the data gathered in that survallance, all samples randomly collected from small-scale dairy farms ,local markets, selling milk and mobile venders in all six localities, that tested by using Ballya test in Central Veterinary Research Laboratory (CVRL)in Atbara for the presence of antibiotics residues.Thirty seven(20%)samples were collected from Aldammarlocality,seventyeight(47.03)samplesfromAtbara,eighteen(9.7%)samplesfromShandi,twelve(6.5%)samplesfromAlAlmatama,towenty(10.8%)samples from Barabar and twenty(10.8%)samples from Abohamad locality.Chi- square test was used for comparison between different localities and between farms , markets and venders samples at 5% probability level , to determine the percentage of antibiotic residues.Out of the 185milk samples , seven(3,8%)samples were positive to antibiotic residues , asfollows 2 ( 28,6 %) samples found in Aldamar locality , 2 ( 28,6%) samples one of them from farm and the other was bought from venders in Atbara locality and 3 (42,8%) samples were bought from market and vender in Shandi localitywith p-value <0.055..The study Recommends a further screening for residues at the milk collection centers and investigation of the milk production practices among small-scale dairy farmers. This will provide a standing ground for designing appropriate and effective small scale milk production practices which will reduce milk contamination and help to protect the health of consumers in River Nile state.
