Abstract:
Agro-based products are primary to all human food sources. Contamination in these is also the easiest way of human health getting affected in large scale. Among the myriad of agro-based products, commercially produced milks and eggs were sampled. Chicken eggs were sampled from Dhaka and its nearby other seven districts covering the central region of Bangladesh. Dhaka, Narsingdi, Kishoreganj, Mymensingh, Tangail, Gazipur, Narayanganj, and Munshigonj were selected for the study. Twelve eggs were randomly sampled from each district’s egg stock market. In Dhaka, Gazipur, and Tangail’s market both brown and white colored eggs were found. Six eggs from each type were sampled from these three districts. In the rest five districts only brown colored eggs could be found. Commercial liquid milks of 13 prominent milk producers have been sampled with replication.

Chicken eggs are the most commonly eaten eggs, and are highly nutritious (FAO, 2007). They supply a large amount of complete, high-quality proteins (which contains all essential amino acids for
