Bacteriological assessment of Abattoir facilities and environment in Keffi, Nigeria

Abstract

The abattoir industry is a vital constituent of the livestock industry because it makes available domestic meat to over 150 million people and makes jobs available for a large number of people in Nigeria. The study is aimed at the assessment of bacteriological of abattoir facilities and environment in Keffi. Standard microbiological methods were used in isolation and identification of different bacteria species. The overall bacteria isolated were 80.0%, where the Slaughter floor and wastewater had the highest (100%) and butchers hands had the lowest (55.0%). From butchering knives, the highest recorded was Escherichia coli (50.0%) and lowest was Entercocci sp (5.0%). From butchers hands Escherichia coli were highest (30.0%) isolated. From the wastewater the highest was Pseudomonas sp (55.0%). Salmonella sp had the highest haemolysin production with 100% from butchering tables and 92.3% from slaughter floor. From butchering knives Salmonella sp, Staphylococcus aureus, Salmonella sp, Proteus sp and Entercocci sp had the highest haemolysin production (100%). Highest percentage Congo red dye binding observed was from Salmonella sp from slaughter floor (92.3%), Pseudomonas sp (100.0%). From butchering knives survival rate in low pH the highest recorded was Escherichia coli (73.6%) from Slaughter floor, from butchering knives, the highest was Staphylococcus aureus and Pseudomonas sp (100%). The antimicrobial susceptibility showed that E. coli was highly susceptible to gentamicin (75.9%), and low susceptible to chloramphenicol (36.8%). S. aureus was highly susceptible to gentamicin (81.1%), and low susceptible to Trimethoprim (27.2%). From findings of this assessment it was recorded that most of bacteria isolated were pathogenic bacteria. There is need for developing a good disposal of waste from the abattoir to avoid spread of pathogenic bacteria in the community.
