“Reduced-oxygen packaging” means the reduction of the amount of oxygen in a package by mechanically evacuating the oxygen, displacing the oxygen with another gas or combination of gases, or otherwise controlling the oxygen content in a package to a level below that normally found in the surrounding atmosphere, which is 21 percent oxygen.

“Reduced-oxygen packaging” includes methods that may be referred to as altered atmosphere, modified atmosphere, controlled atmosphere, low oxygen, and vacuum

packaging, including sous vide.
