BACTERIOLOGICAL QUALITY OF INDOOR AIR ENVIRONMENT IN PRIVATE AND GOVERNMENT OWNED ABATTOIRS IN BENIN CITY, NIGERIA

The airborne bacterial load of two abattoirs, private and government abattoirs in Benin City was studied using the settled plate methods. air samples were collected during after slaughtering operations monthly for a period six months, between October, 2011 March, 2012. temperature relative humidity determined each sampling time. plasmid DNA profile isolated alkaline lysis method. reading ranged 25 0C 34 abattoir 26 35 abattoir. 46 % 67 65 mean counts on nutrient agar blood from 17.55 x 102 ± 3.77cfu/m3 to 108.0 10.35cfu/m3 12.84 1.51 cfu/m3 49.71 3.61 slaughtering. 24.63 3.75cfu/m3 58.30 6.49 15.62 2.97 114.13 19.75 grown eosine methylene blue 1.057 2.58 22.54 5.70 2.44 1.41 9.87 1.05 5.62 24.40 4.66 1.06 4.24 21.08 3.94 result revealed isolation seven isolates which include Staphylococcus aureus, epidermidis, Streptococcus sp., Bacillus Pseudomonas Klebsiella Escherichia coli. frequency occurrence distribution Staphylococcus. aureus (48.75%) sp.

Hence, measures taken checkmate this menace caused poor hygienic systems
