A Warning to Beer Drinkers!!

A Warning to Beer Drinkers
Recent research report found that, arsenic has been added in the beer filtration process. It is known that, In 2008, Italian beer withhold high level of arsenic. It is very important to note that, arsenic is highly dangerous element to the human beings.
