This project work is carried at the isolation and characterization of pathogenic bacteria from hawked suya meat, were 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 5 ml sterile pipette and test tubes. The dilution were then cultured on different media, macconkey agar, nutrient agar and blood agar end later incubated at 37⁰c for 24 hours. Discrete bacteria colonies were observed and each colomy was gram stained and examined microscopically. Biochemical test were carried out to confirm the particular bacteria present. Bactering isolated were Staphylococcus aureus, Bacillus, lactobacillus, streptococcus and Escherichia coli. Most at this microorganisms isolated are pathogenic and are toxic when ingested in contaminated suya meat. They are capable of causing illness. For instance staphylococcus aureus produce air exotizcin and can with stand temperature of 100⁰c for 30 minutes. When ingested, if cause intoxication manifesting in 4-5 hours with acute diarrhoes vomiting and gastroertrities lasting 6-8 hours.

INTRODUCTION

Meat is an animal product. It is that part of animal that provides major source of protein in west African food.

There are different types of meat from different types of animals, eg pork meat (pig) multon (goat) beef (cow).

Meat can be served as prepared meat product eg corn beef, fried meat, cooked meat and suya, meat (smoke meat). Meat is perishable food and its composition is ideal for the growth of wide range of spoilage bacteria. Public concern has vison due to numerous food scandals such as those surrounding bovine spongiform encephalopathy and roof and mouth disease epidemics and food borne disease which remain substantial burden . we can meet those challenges with an improved and global food safety control system. One possible improvement would be a repid and accurate detection system for microbial spoilage. This technique should ideally also be non destructive and give result in real time for application in highly automated food processing environment.

Suya meat is produced by smoking the raw beet with the addition of some syices, salt, oil, groundnut cake and flavors. The meat is first sliced into smaller pieces and the spices are rubbed onto it, it is later oven driedor over local source of heart. This allows the meat to get dried properly with the right taste before is gold to the consumers.

This is gold at a specific joint or howked when it is Gold at joint it is constantly kept warm over fire source. The hawked saya meat is carried about in open basin from place to place thereby exposing it to dust and other effects of the environment so doing harmful organisms find their ways into the meat there by coursing for poisoning.

Food poisoning is an illness with acute gastro ertritis as a major symptom caused by the ingestion of food counting my harmful micro organizer or harmful substances. Tomatari (1983).

Some of the micro organisms present in suya causes food poisoning when consumed are Salmonella typhi staphylococcus aureus clostridum butilinum, clostridium preferring Bacillus cereces streptococcus progenies.

Some of these micro organisms in meat cause off shavours which make the meat to be unfit for eating and also reduce the taste value.

AIMS OF OBJECTIVE

This project research is designed to isolate and identify the common spoilage organisms of suya meat often production thereby ensuring the safety of the population at risk in eating containineted suya meat
