A brand of commercially available juice products was purchased from the main market of Ado-Ekiti
metropolis, Ekiti State, South-West of Nigeria.
A total of three fruit juices of multi fruits juice, orange juice, and coconut-pineapple juice, which are
commonly consumed were screened for the survival rate of Escherichia coli, Salmonella species, and
Shigella species and the growth pattern of these organisms were also observed. In the fruits analysed; the
total plate count were 2.35 × 104 Log cfu/ml, 2.44 × 104 Log cfu/ml, and 2.57 × 104 Log cfu/ml.
Escherichia coli range between 0.68 × 104 Log cfu/ml, to 0.01× 104 Log cfu/ml, Salmonella species range
between 0.86 × 104 Log cfu/ml, to 0.01× 104 Log cfu/ml,, and Shigella species range between 0.84 × 104
Log cfu/ml, to 0.03 × 104 Log cfu/ml. Among the pathogenic microorganisms used, only Escherichia coli
was able to survive after five days, Shigella Species died off after three days, while Salmonella species
died off after four days. Many of these organisms can cause diseases in humans which indicate that the
fruit juices must full fills the guidelines for the microbiological quality of juices and steps must be taken
to improve the microbial quality of products and prompt consumption is recommended not to keep it after
lid has been removed.
