Food poisoning and infection by bacterial and fungal genera pose obvious health threat to both
animals and humans. Pfizer, Guinea, Extra, Top, NOM and Master brands of feed sold in Owerri Metropolis were
analysed for their bacterial and fungal quality. The genera of bacteria and fungi isolated and their percentage
occurrence were
Listeria
spp (10.4%),
Staphylococcus
spp. (50%),
Bacillus
spp (27.1%),
Pseudomonas
spp.
(12.5%),
Escherichia coli
(29.2%) and
Salmonella
spp. (25%),
Aspergillus
spp (56.3%),
Fusarium
spp (58.3%),
Penicillium
spp. (62.5%) and
Rhizopus
spp (89.6 %). The mean bacterial and fungal counts vary with samples
while statistical analysis for the goodness of fit revealed no significant difference between the observed and
expected values at 1.0% level.
