Coffee creamer (powdered) is shelf-stable at room temperature: cool, dry pantry, sealed — refrigerating after opening is optional and mainly preserves quality. Refrigerating it mainly preserves quality rather than safety.
Look for: Sour or off smell; Mould or fuzzy spots; Curdled, slimy, lumpy, or separated texture; Yellowing or other discoloration. Never taste something to test it — when in doubt, throw it out.
