How Often Should You Wash Reusable Grocery Bags?
Wash reusable grocery bags after each grocery use when possible, and always after raw meat, produce, leaks, odors, or damp storage.
Wash reusable grocery bags after each grocery use when possible, especially if they carried raw meat, seafood, eggs, produce, or anything that leaked. At minimum, wash or disinfect a bag immediately after raw-food contact, spills, dampness, odor, or use for non-food items. Dry bags completely before storing them.
Reusable bag cleaning schedule
Regular grocery trip
After each use when possible
Bags contact carts, counters, packaging, and food residue
Raw meat, poultry, seafood, or eggs
Immediately after use
Juices and packaging can cross-contaminate other foods
Produce or damp items
After use or when damp
Moisture can carry soil and encourage odors
Bag used for non-food items
Before groceries again
Gym gear, shoes, and household items do not belong in food bags
Insulated or laminated bag
Follow material care
Some need wiping or hand washing instead of machine washing
Separate bags by job
Use dedicated bags for raw meat, produce, pantry goods, and non-food items. That reduces the chance that a bag that carried leaking chicken or muddy shoes is later used for apples, bread, or ready-to-eat food.
