Adetunde L. A., Glover R. L. K., Oliver A. W. O. and Samuel T..

Abstract
The study was to determine the source, distribution and the level of contamination in Chevon (goat meat) and beef processed by butchers in slaughter house and open market, considering various body regions such as the neck and thigh during the period of April to June 2010 in Navrongo in the Kassena Nankana. A total of 20 samples of meat were sampled from the open market and slaughter house. Ten (10) samples of Chevon from the neck and thigh were collected. Same sample were collected for beef. Bacteriological analysis of the samples such as total and faecal coliform; total viable bacteria counts and salmonella counts were determined using multiple tube fermentation method and standard plate count method respectively. The mean TVBC per gram of goat meat sample from the neck and thigh were 1.58107 and 3.62107 respectively for the goat meat from the slaughter yard. Goat meat sampled from the open market also had the neck and thigh as 5.18107 and l7.0107 respectively. The Mean TVBC of beef per gram of meat sample from the neck and thigh were 2.12107and 3.26107 respectively for the beef from the slaughter yard. Beef sampled from the open market also had the neck and thigh as 4.16107 and9.97107 respectively. The mean values of total coliform counts in neck and thigh of goat meat and beef processed at the slaughter yard and open market were >1600. The mean values of faecal coliform counts in neck and thigh of beef and chevon processed at the slaughter yard and open market were >1600.The values of salmonella counts in neck and thigh of goat meat processed at the slaughter yard were 0.22102and 1.36102 respectively. Whereas goat meat sampled from the open market also had the neck, thick as 1.86102 and 1.98102 respectively. The mean values of Salmonella counts in the neck and thigh of beef processed at the slaughter yard were 0.86102 and 0.44102 respectively. Beef sampled from the open market also had the neck and thigh as1.64102 and 1.42102 respectively.

Key words: Chevon, Navrongo, Kassena-Nankana, Slaughter house, Open-market place, Total Viable Bacteria Counts (TVBC), Total Coliform Counts (TCC), Fecal Coliform Counts (FCC)
