Venezuela ? Meat cuts vanished from Venezuelan supermarkets this week, leaving only unsavory bits like chicken feet, while costly artificial sweeteners increasingly have replaced sugar and many staples sell far above government-fixed prices.

President Hugo Chavez’s administration blames the food supply problems on unscrupulous speculators, but industry officials say government price controls that strangle profits are responsible. Authorities on Wednesday raided a warehouse in Caracas and seized 7 tons of sugar hoarded by vendors unwilling to market the inventory at the official price.

Major private supermarkets suspended sales of beef earlier this week after one chain was shut down for 48 hours for pricing meat above government-set levels.
