The cost of pork rose more than 10 percent in the past two months, according to Xinhua News Agency''s price system on national farm produce.
All provinces, regions and municipalities saw rises, except Hainan, according to data collected between Nov 19 and Jan 19.
Shandong led the way with an 18.2 percent rise in pork prices. Shanxi, Liaoning, Henan, Hubei and Shaanxi saw rises of more than 15 percent. Pork is a staple meat in China.
The country has experienced its lowest temperatures in 28 years since the end of November, which has affected the production and transportation of farm produce.
Food prices account for almost a third of the weighting in the country''s calculation of the consumer price index (CPI), the key gauge of inflation.
China''s CPI grew 2.5 percent year-on-year in December, the fastest since June.
