Cucumbers are on display at a market in central St. Petersburg June 9, 2011. Prime Minister Vladimir Putin said last Friday that Russia will not consider lifting a ban on European Union vegetable imports until it hears from the EU about the source of a deadly E.coli outbreak. The cucumbers are brought from Kuban, a district in southern Russia, according to the price tag. REUTERS/Alexander Demianchuk (RUSSIA - Tags: HEALTH POLITICS BUSINESS AGRICULTURE)
