EurekAlert: Coelhan pointed out that beers produced in at least six other countries had higher arsenic amounts than German beers, according to a report published four years ago. He said that breweries, wineries and other food processors that use kieselguhr should be aware that the substance can release arsenic. Substitutes for kieselguhr are available, he noted, and simple measures like washing kieselguhr with water can remove the arsenic before use.
