&quot;Any contained item that can fit inside a refrigerator, whose quality would degrade significantly more when kept at room temperature rather than at 1-4°C, by the estimated time of use&#x2F;consumption.&quot;<p>The term &quot;contained&quot; above is restrictive, and probably needs further precision. Only things that thrive inside an opaque and sealed container would fit the definition above. Otherwise, things that can affect the quality of other items (i.e., gas emanation), things that need light, things that need oxygen, things that need a specific range of moisture, things that can grow and&#x2F;or move, would all need their containers to provide these conditions and&#x2F;or have a dedicated location inside the refrigerator.
