Abstract

Background: Milk is one of the most nutritious drinks in the world which is suitable for people of all ages. The quality and safety of such drink are of utmost importance for public health issues. Residual antibiotics and microbial quality of milk have thus become as major concerns to consumers. Therefore, present study was conducted to detect antibiotic residues and assess microbial quality of fresh bovine milk samples both at origin and vendors level in Dhaka city and nearby areas of Bangladesh.

Materials and Methods: A total of 150 milk samples were aseptically collected from randomly selected farmers and retailer. Antibiotic residues in milk was detected by streak plate techniques on nutrient agar plate using Bacillus subtilis as test organisms. Total bacterial counts and coliform counts were determined following the pour plate technique using nutrients agar and MacConke’s agar, respectively.

Results: Antibiotic residues were detected in 10.67% of total milk sample while 18% of farmers’ milk and 7% of retailers’ milk were positive for the same. The mean standard plate count of raw milk collected from farms and retailer were 7.63 ± 0.14 log10 cfu/ml and 8.46 ± 0.23 log 10 cfu/l of milk, respectively. In contrast, total coliform count in fresh milk samples collected from farms and retailer were 2.64 ± 0.21 log10 cfu/ml and 3.92 ± 0.05 log10 cfu/ml of milk, respectively.

Conclusion: Milk produced and sold in the study areas could be considered as of fair quality in terms of microbial load. However, presence of antibiotic residues in milk could pose human health risk. Therefore, awareness should be created on the sensible use of antibiotic and obedience to drug withdrawal period.
