ABSTRACT

Evaluation of microorganisms on garri milling machine was evaluated for the presence of bacteria in garri milling machine was evaluated. In the Total Viable Bacteria Count for samples from environment and swab samples (Site 1), Plate P3 for enviroment sample had the highest count of 5.6x104cfu/ml while plate P2 had least count of 3.9x104cfu/ml for morning.  Plate P2 for enviroment sample had the highest count of 4.7x104cfu/ml while plate P1 had least count of 4.0x104cfu/ml for evening Plate P3 for swab sample had the highest count of 4.3x104cfu/ml while plate P1 had least count of 3.0x104cfu/ml for morning.  Plate P3 for enviroment sample had the highest count of 2.9x104cfu/ml while plate P2 had least count of 1.6x104cfu/ml for evening.  Lactic Acid Bacteria Count for samples from environment and swab samples (Site 1), Plate P2 for enviroment sample had the highest count of 3.0x106cfu/ml while plate P1 had least count of 2.6x106cfu/ml for morning.  Plate P1 for enviroment sample had the highest count of 7.0x103cfu/ml while plate P2 had least count of 4.5x103cfu/ml for evening Plate P3 for swab sample had the highest count of 1.5x103cfu/ml while plate P1 had least count of 1.0x13cfu/ml for morning.) shows Plate P3 for enviroment sample had the highest count of 2.2x103cfu/ml while plate P1 had least count of 1.9x103cfu/ml for morning.  Plate P3 for enviroment sample had the highest count of 0.72x103cfu/ml while plate P2 had least count of 0.64x103cfu/ml for evening Plate P2 for swab sample had the highest count of 0.70x103cfu/ml while plate P3 had least count of 0.60x103cfu/ml for morning. Plate P2 for enviroment sample had the highest count of 4.0x104cfu/ml while plate P1 had least count of 2.8x104cfu/ml for evening Plate P3 for swab sample had the highest count of 5.5x104cfu/ml while plate P1 had least count of 4.7x104cfu/ml for morning.  Plate P1 for enviroment sample had the highest count of 0.91x104cfu/ml while plate P2 had least count of 0.61x104cfu/ml for evening. Lactic Acid Bacteria Count for samples from environment and swab samples (Site 2) shows that Plate P2 for enviroment sample had the highest count of 4.2x106cfu/ml while plate P3 had least count of 3.4x106cfu/ml for morning.  Plate P1 for enviroment sample had the highest count of 0.83x103cfu/ml while plate P3 had least count of 0.75x103cfu/ml for evening Plate P1 for swab sample had the highest count of 1.8x103cfu/ml while plate P3 had least count of 1.6x13cfu/ml for morning.  Plate P2 for enviroment sample had the highest count of 3.6x103cfu/ml while plate P1 had least count of 2.2x1063cfu/ml for evening. The Total Coliform Count for samples from environment and swab samples (Site 2) Plate P2 for enviroment sample had the highest count of 0.85x103cfu/ml while plate P3 had least count of 0.81x103cfu/ml for morning. Nine (9) bacteria species were isolated from this study and they includes, Bacillus sp., Micrococcus sp., Pseudomonas sp., Serratia sp., Klebsiella sp., Leuconostoc sp., Lactococcus sp.,S. aureus and Lactobacillus sp. Three (3) yeast species were isolated from this study and they includes, Saccharomyces cerevise, Candida sp and Pichia sp. One (1) mold specie, Fusarium sp., were isolated from this study. Occurrence of bacterial isolates from swab and environment samples Shows that Lactobacillus (15%) and Bacillus sp (15%) had the highest bacterial occurrence in this study. Serratia sp (8%), Pseudomonas sp (9%) and Klebsiella sp (9%), had the least occurrences. Other bacteria had percentage occurrence of Lactococcus sp (12%), Leuconostoc sp (12%), S. aureus (10%). Saccharomyces cerevisae (37.83%) had the highest percentage occurrence, while Fusarium sp (10.81%) had the least occurrences. Candida (27.02%), and Pichia sp (24.32%) had their own occurrences in this study.
