This present study was designed to evaluate the occurrence of Escherichia coliO157:H7 from Nigerian currency notes (Naira) collected from butchers at the meat market in Karu Abattoir, Abuja. A total 189 currency notes sampled from the eight currency denominations were subjected to cultivation and isolation using Eosine methylene blue (EMB) and Sorbitol-MacConkay(SMAC) agar respectively, in which isolates were obtained. All the 189 (100%) naira notes sampled were contaminated with bacteria, andout of the 189 samples, 12 (19.7%) were contaminated with E. coli, of which5 (41.7%) were confirmed to beE. coli O157:H7. Currency notes can potentially serve as fomite in transmitting microorganisms such as E. coliO157:H7 which causes enteric diseases in humans. Also poor handling practices of currency notes poses a critical threat to public health.

A total of 500 gall bladders were harvested from 227 (45.4%) cattle, 10 (2.0%) sheep and 263 (52.6%) goats after slaughter from the abattoir and slaughter slabs within Zaria metropolis. Out of the animals sampled, 240 (48.0%) were positive for eggs of liver flukes. There was a significantly higher level of infection in cattle (39.2%) than small ruminants (8.8%). Among the infected animals, 99 (50.51%) of the infected cattle had mixed infections with eggs of F. gigantica and D. hospes (p<0.05). A non-statistically significant higher rate of infection was observed in cows 47 (88.68%) than bulls 149 (85.63%) (p> 0.05). Season-specific prevalence showed a significantly (p<0.05) higher rates of infections during the rainy season than during the dry season. This study therefore confirms a high prevalence of liver fluke infections among animals slaughtered in Zaria for consumption, therefore adequate measures needs be taken to control the infection in order to reduce the economic losses accruing to this infection.
