Last week, the retail price of eggs rose 0.6 percent from a week earlier, but remained down 5.4 percent from the same period last year.

The price of pork, a staple meat in China, dropped 0.4 percent from a week earlier, the ministry said.

Prices of beef, lamb and chicken were up 0.7 percent, 0.4 percent and 0.3 percent, respectively, said the ministry.

Food prices account for nearly one-third of the prices used to calculate China's consumer price index (CPI), which eased to 2.2 percent in June, its lowest level since January 2010.

The National Bureau of Statistics is scheduled to release its July CPI data on Thursday.
