2. DON’T Leave Pet Food Sitting Out Too Long
How long dry food can be left out will vary depending on the food and manufacturer. Some companies use natural and artificial preservatives that generally are good until expiration, even when open. The best recommendation is to contact the manufacturer to find out the recommendation for your pet’s specific food.
Canned food, once opened, can be left out from 2 to no more than 4 hours. Any unused canned food should be immediately put in the refrigerator. Contact the pet food manufacturer to find out their recommendations for how long the food can still be fed once opened and placed in the refrigerator.
Ideally, unopened dry and canned foods should be kept at room temperature and away from heat, humidity and infestation.
