About 600 million people worldwide develop an illness after ingesting a contaminated food or drink and 420 000 die every year. Random samples of zobo drink and calyces were collected from Idah and Ugwolawo communities and analysed for their microbiological safety and quality criteria, such as Total Viable Count (TVC) of bact, oreria, Total Mould and Yeast Count (TMYC), Total Coliform Bacterial Count (TCBC) and Escherichia coli detection. Safety and quality indicators were isolated on/in nutrient agar (TVC), sabouraud dextrose agar (TMYC), MacConkey broth (TCBC) and eosin methylene blue agar (E. coli). The results from the study showed that the samples had TVCs of 5.01 to 5.32 log CFU/mL, which exceed the acceptable limit of <104 CFU/mL for ready to eat foodstuff. The highest TMYC (log 3.24 CFU/mL) was obtained from dry zobo calyces while the high TCBCs recorded fo.. View More»
