Illinois-Based Company At Center Of China Meat Scare

Starbucks and Burger King are getting dragged into the scandal over suspect meat in China. 

The issue has also spread to Japan where McDonald's says the Chinese supplier accused of selling expired beef and chicken had provided 20 percent of the meat for its chicken nuggets.

Chinese authorities are expanding their investigation of the meat supplier, Shanghai company Husi Food Co. A day after Husi's food processing plant in Shanghai was sealed by the China Food and Drug Administration, the agency says inspectors will also look at facilities and meat sources in five provinces in central, eastern and southern China.

The agency says food safety violations will be "severely punished.''

The scandal surrounding Husi Food, which is owned by OSI Group of Aurora, Illinois, has added to a string of safety scares in China over milk, medicines and other goods that have left the public wary of dairies, restaurants and other suppliers.
