BACTERIAL CONTAMINANTS ASSOCIATED WITH POULTRY FEEDS FROM 3 DIFFERENT COMPANIES (VITA FEED, GUINEA FEED, TOP FEED)
Abstract
Bacterial contamination associated with poultry feeds from three different companies (Vital, Guinea, and Top) was investigated using the streak plate technique. Nutrient agar and MacConkey agar were used as culture media for the isolation of bacteria. The aim of the study was to determine the microbial safety of poultry feeds, identify the bacterial species present, and assess the microbial load of the feeds. The results showed that the highest mean microbial count was recorded in Vital feed (1700 cfu/ml), followed by Guinea feed (1490 cfu/ml), while Top feed had the lowest mean microbial count (1070 cfu/ml). The predominant bacterial organism isolated was Staphylococcus aureus, followed by Salmonella typhi and Bacillus cereus, while Pseudomonas aeruginosa was the least isolated organism. Vital feed recorded the highest occurrence of Staphylococcus aureus. The study revealed that poultry feeds were generally contaminated with bacteria, although microbial load decreased with increasing acidity. This finding indicates that acidity plays a role in reducing bacterial growth in poultry feeds.
