Isolation and Characterization of Bacteria Associated With Hawked Suya Meat

ABSTRACT

This project work is carried out with the isolation and characterization of pathogenic bacteria from hawked suya meat, which was bought in full from the sellers and was collected in raps of aluminum foil. It was then taken to the laboratory for analysis the samples were homogenized and serial dilution of the sample was made out using a 5 ml sterile pipette and test tubes. The dilution was then cultured on different media, McConkey agar, nutrient agar, and blood agar end later incubated at 370c for 24 hours. Discrete bacteria colonies were observed and each colony was gram stained and examined microscopically. Biochemical tests were carried out to confirm the particular bacteria present. Bacteria isolated were Staphylococcus aureus, Bacillus, lactobacillus, streptococcus, and Escherichia coli. Most of these microorganisms isolated are pathogenic and are toxic when ingested in contaminated suya meat. They are capable of causing illness. For instance, Staphylococcus aureus produces air exotizcin and can withstand the temperature of 1000c for 30 minutes. When ingested, if cause intoxication manifesting in 4-5 hours with acute diarrhea vomiting and gastroenteritis lasting 6-8 hours.
