In many developing countries around the world and in India, milk cans play an essential role in transporting milk from various productions / collection centers to the dairy or the processing centers. Since these cans also act as storage vessel by having raw milk in them for hours together, they were found to be among the prime source of microbial contamination to the milk, which has got direct implication on the quality of processed milk and other end products and further on the public health.
These facts call for proper research on the effects of milk cans on microbial quality of milk kept in them. A study, hence conducted on two major types of materials used for milk cans, Aluminum alloy and Stainless Steel, with reference to cleaning and sanitation efficiency gave some alarming results.

These results support all public awareness and preference for Stainless Steel against aluminum alloy for milk cans and even house-hold utensils.It's time for policy makers to think.All these above discussion accentuates the utility of Stainless steel over other conventional materials in food handling and processing industry.
