The Brazilian government and FIFA have been condemned by a German health lobby for lifting the ban on the sale of beer in World Cup stadiums.
"It is a health, political and security scandal," said Raphael Gassmann, director of the German Centre for Addiction Issues (DHS).
Brazil passed a law in 2003 which banned the sale of alcohol in stadiums in a bid to halt spectator violence.
Gassmann called for "a change of mentality" by FIFA. "Economic interests must not prevail over the health and security of spectators," he told a Berlin press conference.
"We demand that FIFA respect the law of a democratic country like Brazil," he added.
Brazilian brewers expect a major sales boom during the World Cup.
