Abstract

In the present paper, efforts have been made to evaluate microbial contaminants in term of  CFU/g of three sealed Bournvita samples (B1, B2, B3) and three sealed Horlicks samples (H1, H2, H3) at interval of one month for 120 days (4 months) under controlled laboratory conditions. Further to find out the effect of consumer’s handling on microbial load, these packs after 120 days were distributed to consumer A, B and C respectively and were examined for extended period of 28 days at interval of 7 days. The results revealed that microbial contaminants were present since beginning (when opened) in all the energy food samples. Maximum microbial load in Bournvita sample was recorded in B2, followed by B3 and B1 respectively and in Horlicks, it was maximum in H2 followed by H3 and H1 respectively. In general the microbial contaminants were more in Bournvita than Horlicks. No significant change occurred in their CFU till 120 days but handling process enhanced the contaminants significantly both in their quality and quantity in term of microbial group. Fungi and Actinomycetes were recorded in sampling from the samples of consumers A, B and C. Total CFU enhanced from both energy food and reached in several lakhs. Total Bacterial species isolated and identified were Staphylococcus aureus, Bacillus cereus, Enterococcus, Escherichia coli, and Pseudomonas aeruginosa.  After 2 and half years (Feb 2010) the bacterial count was found 3, 00000 CFU/g of Horlicks and fungal count was 250CFU/g.
