Abstract
A total of 125 sample were investigated in the following order: 25 each of fish samples were collected before and after adding of (organic material) poultry droppings to fish farm, 25 water samples of fish farm were collected before and after addition of poultry droppings as well as 25 poultry droppings sampls. The collected samples were examined for APC at 35°C and 5°C, Enterobacteriaceae and Pseudomonas / Aeromonas counts. The counts in fish muscle were 5 x 103 ± 1.5 x 102, 9.4 x 102 ± 1.23 x 102, 7 x 102 ± 2.3 x 102 and 2x102 ± 4.3 x 10 before addition of poultry droppings respectively. Such counts were significantly increased at p< 0.05 each constituting, after addition of the droppings 9 x104 ± 3.64 x 103,9.5 x 103 ± 2.2 x 103, 6.75 x 103 ± 2 x 103 and 1.3 x 103 ± 1.4 x 102 organisms/gm fish muscle respectively. Water samples showed that the counts were 8.6 x 103 ±2 x 103, 4 x 103 ± 9 x 102 , 2.1 x 102 ±5 x 10 and 4.0 x 102 ± 8.0 x 10 or- ganisms/ml before adding of poultry droppings. respectively while such counts were significantly increased at p<0.05 to 9 x 106 ± 2 x 106, 6 x 105 ± 1.5 x 105, 4.3 x 105 ± 1.4 x 103 and 7.2 x 104 ± 1.3 x 103 organisms/ml respectively after addition of poultry droppings to fish farm water. While the counts in poultry droppings were 4.2 x 109 ± 1 x 109, 6.0 x 106 ± 2 x 106, 1.3 x 106 ± 5.0 x 105 and 8 x 104 ± 2 x 104 organisms/gm respectively. Salmonellae, Yersinia enterocolitica, Pseudomonas aerugenosa, Aeromonas hydrophila and Campylobacter jejuni could be isolated from fish after add of poultry droppings with percentages 28, 36, 40,16 and 28 respectively. The public health risks of the isolated organisms were also discussed.
