ABSTRACT
Microbiological quality of vegetables cultivated
in soils treated with poultry manure was determined. Four vegetables:
waterleaf, pumpkin, cucumber, and tomatoes were used. Samples were examined for
microbial contamination and bacterial isolates: Escherichia coli,
Staphylococcus aureus, Klebsiella spp., Bacillus subtilis, Salmonella spp. and
Shigella spp. were recovered from the soils and vegetables. The total bacterial
count of the soil samples ranged from 75x10cfu/ml (S3) to 5.9x10cfu/ml (S4) while
the total bacterial count for the vegetable samples ranged from 2.65x 10cfu/ml
(P) to 1.50x10°cfu/ml (W). The total coliform count of the experimental soil
samples ranged from 1.65x 10'cfu/ml (S3) to 6.9x10cfu/ml (S4) while that of
vegetable samples ranged from 1.20x10cfu/ml (P) to 7.2x10cfu/ml (W). S1 was
significantly different from S2 and S4 for the total bacteria count for the
soil samples while P and W were significantly different for the vegetable
samples (P< 0.05). For Salmonella-Shigella plate counts, SI and S4 were
significantly different and S2 and S3 were same (P< 0.05); while the
vegetable samples, P, W, C and T were significantly different (P< 0.05). S
1, S2, S3, and were significantly different for the total coliform count for
the soil samples and same for P, W and C (P<0.05). Sensitivity screening for
the isolates showed that Bacillus subtillis was most sensitive to Ofloxacin
(25mm) while Staphylococcus aureus was most sensitive to Ofloxacin (22mm).
Shigel/a was most sensitive to Ciprofloxacin (25mm) while E. coli showed
highest sensitivity to Ciproflacin (25mm) and Ofloxacin (25mm). In addition,
Klebsiella was most sensitive to Ciprofloxacin (23mm) and Ofloxacin (23mm) and
Salmonella showed resistance to the antibiotics. This study demonstrated that
there is a high level of microbial contamination associated with the
cultivation of vegetables in soils in which organic manure has been applied to
which is of risk to the consumers
