1. OSI Group

It isn't a household name, but the company at the center of the food scandal in China helps make some of the world's most popular foods.

OSI Group, a privately-held company based in Aurora, Illinois, was thrust into the spotlight in July when a Chinese TV station reported that one of its Shanghai plants repackaged old beef and chicken and slapped new expiration dates on them.

The scare has ensnared some famous chains that got ingredients from a unit of OSI (pronounced OH-see) in the region called Husi Food Co.

The controversy deepened when five workers of Husi were detained by police. An official with China's food safety regulator told the media that some of the illegal conduct it uncovered was an arrangement "organized" by Husi.
