Further price rises for meat and vegetables caused by heavy snowfall and transport chaos across the central mainland have hit Shenzhen residents. Fang Yixing, a mother-to-be from Sichuan province, bought tofu and eggs from Futian wet market yesterday, as an alternative to record-high pork prices of 32 yuan per kilogram. She said vegetable prices had soared by more than 50 per cent. She spent two yuan for three heads of celery, which used to be half that price. The city's pricing watchdog said: 'Price rises for foodstuffs have been caused by the recent extreme weather and disarray in transport. One-tenth of the pigs supplied by the provinces of Hunan and Hubei froze to death on icy roads on the way to the Pearl River Delta.' The Southern Metropolis Daily reported that it now takes four days to transport pigs from Changsha , Hunan, to Guangdong. To ease the pork shortage, all expressways in Guangzhou had lifted toll charges for trucks carrying meat or vegetables beginning on Monday, the report said. The vegetable trade in Shenzhen's two major farmers' markets was down by 1,000 tonnes a day. Buji Farmers Market recorded an average 40 per cent price rise for 47 types of vegetables. The supply of cabbages, potatoes and lotus roots from northern China was reduced by 50 per cent. Xinhua said the Guangdong Price Bureau issued a circular on Monday warning shops and retailers against hoarding, and threatening stiff fines for violators.
