Abstract
Aim:
To assess the bacteriological quality of ice creams
marketed in Thrissur town, Kerala.
Materials and
Methods: Twenty seven ice cream samples randomly
collected from selected retail outlets and street
vendors in the town over a period of two months were
analyzed for total viable count and for the presence
of coliforms, Escherichia coli, Staphylococcus
aureus, Salmonella spp. and Listeria monocytogenes.
Results: Total Viable Count ranged from 1.2 x
102 to 8.2 x 103 cfu/g in industrial brands whereas
in street vendor samples it was high in the range of
5.2 x 105 to 6.6 x 106 cfu/g. Coliform counts were
high in 30 % of the samples. 27 % of the samples had
high Staphylococcal count. E coli were isolated from
two samples from street vendors and Salmonella spp.
from one of the samples. Listeria spp. was not
isolated from any of the samples. Conclusion: The
presence of potential pathogens in the ice cream
samples reveals the significance of implementation
of quality control measures in marketing ice creams
thus reducing the public health hazards.
