Microbiological Assessment of different species of apples (Granny smith, Red delicious and Goldrennette) sold in Owerri Metropolis, Imo State
Abstract
The microbiological assessment of different species of apples (Granny smith, Red delicious and Gold rennette apples) sold in Owerri Metropolis, Imo Slate was carried out using standard microbiological procedures. Three species of apples were bought from four different vendors at different locations within Owerri. Total viable bacterial counts recorded ranged from 1.0 x 103cfu/g to 1.32 105cfu/g. Total coliform counts recorded ranged from 1.0 x 103cfu/g to 1.6 x 104cfu/g. Total fungal counts recorded ranged from 2.0 x 103cfu/g to 1.4 x 104cfu/g. Bacterial isolates from the apples were; Staphylococcus aureus 3(9.68%), Pseudomonas aeruginosa 4(12.90%), Corynebacteriumspecies 8(25.81%). Bacillus species 5(16.13%), Proteus species 4(12.90%), Micrococcus species 5(16.13%) and Klebsiella species 2(6.45%). Fungal species isolated from the apples were; Penicilliumspecies 6(35.29%), Saccharomyces species 4(23.53%), Kluyveromycesspecies 3(17.65%) and Mucor species 4(23.53%).The prcsenceof pathogenic organisms on the fruits is of public health concern. The fruits should be properly washed before consumption.
