BEIJING - Intentional contamination by food producers and processors driven by profits are largely being blamed for the food safety crisis in China, officials with the country's top food security watchdog said on Monday.

"Instead of sheer accidents, most of the recent stomach-turning food safety incidents are a consequence of intentional violations of food safety regulations and processing procedures," said Yu Jun, a senior official with the Food Safety Commission under the State Council, China's Cabinet, at the Third China Food Safety Forum.

"Cases include incidents caused by additives, such as melamine, clenbuterol and the steamed buns colored with chemicals found in Shanghai and Zhejiang province," Yu said.
