Survey of the Microbiological Quality in Ice Cream

Abstract

       In fiscal year during 2011-2013, Bureau of Quality and Safety of Food has successfully performed the microbiological quality testing on 375 samples, which were taken from manufacturers and randomly collected from the market in Bangkok and suburb by Food and Drug Administration of Thailand (Thai FDA). The samples were divided into two groups : edible ice. (92 samples) and milk ice cream, modified ice cream and mixed ice cream (283 samples).The results showed that 27 samples (7.20%) did not comply with the Notification of the Ministry of Public Health No. 354 B.E. 2556 (2013), Ice Cream, and No. 364 B.E. 2556 (2013), Food Standard as regards pathogens, due to the quantitation of total bacteria count and Bacillus cereus and the detection of Escherichia coli, Staphylococcus aureus and Salmonella spp. (Salmonella serovar Weltevreden) were 7, 9, 7, 3 and 1 samples or 1.87, 2.40, 1.87, 0.80 and 0.27 percent respectively. When classifying these samples according to ice cream types, edible ice was 8 times better in microbiological quality than milk ice cream, modified ice cream and mixed ice cream, but the statistical evaluation was not significantly different at 0.05 (p>0.05). The relation between senders was found that the samples collected by Thai FDA higher in microbiological quality than those sent from manufacturers, the quality also was not statistically significant different at 0.05 (p>0.05).
