|Abstract: ||In this study, thirty water samples obtained from nvers. streams and ponds used for
irrigation of vegetables at thirty different sites in Jos, Plateau state, Nigeria were analyzed for the
presence Listeria monocytogenes and other Listeria species using the two-step enrichment method.
Ten samples each spinach lettuce and cabbage, which are common vegetables grown in Jos were
analyzed for the presence of Listeria monocytogenes. The results obtained showed that out of the
30 water samples screened 10(33.3%) were positive for Listeria monocytogenes. Ponds accounted
for 50% of the positive samples, followed by streams (33.3%) and rivers (27.2%). Of the ten
samples of vegetables analyzect only two spinach samples were positive for Listena
monocytogenes. Other bacteria species isolated from the water samples include L. onnocue. L.
ivsnovit. L. gray< Bacillus spp, Streptococcus .70, Aeromcoes SPIJ, Pseodorrcnes sJp. Klebsiella
Spp Escherichia coii and Staphylococcus aureus. Dry season farmers and vegetables handlers in
the irrigated fields should be educated on measures aimed at minimizing or eliminating the hazard
associated with Listeria monocytogenes.|
