BEIJING, April 16 (Xinhua) -- Prices of farm produce in China slightly retreated in the last week, data showed Tuesday.

From April 8 to 14, the overall price for farm produce edged down 0.5 percent on a weekly basis, following a 0.5-percent gain in the previous week, data from the Ministry of Commerce (MOC) showed.

In breakdown, the average wholesale price of 30 types of vegetables went down 1.7 percent on a weekly basis.

The wholesale price of pork and beef both saw a slight decrease from a week earlier, down 0.7 percent and 0.3 percent, respectively.

Food accounts for about one-third of China's consumer price index (CPI), a main gauge of inflation.

The latest official data showed China's CPI rose 2.3 percent year on year in March, compared with 1.5-percent growth in February.

MOC data also showed that producer prices picked up last week, with prices of steel rising 1.1 percent from a week earlier.
