• pick well known brands like the Japanese brand, or Hagen,
• Check date of production  ( if possible)
• Choose foods that have very little residue, normally they are fresher

• keep hamster food in air tight containers, to prevent moisture, as moisture will cause beetles to grow, then the food will be spoilt.
