The short answer
Why Sewer Water Is Unsafe
Sewer water contains bacteria, viruses, and other harmful organisms. Even a small amount can contaminate food and surfaces. Sealed containers are not safe because the water can get under lids or into tiny cracks. You cannot see or smell all the dangers, so it is not worth the risk.
The pros who handle sewer cleanup follow strict safety rules. They treat everything the water touched as contaminated. For your pantry, that means the same approach: if you are unsure, assume the food is unsafe. Your health is more important than saving a few items.
What to Throw Away
Throw away any food that was directly exposed to sewer water. This includes open packages, cardboard boxes, paper wraps, and any food with a porous surface. Also discard items stored in plastic or glass if the water reached the container, because the seal may not be perfect.
Do not try to wash or disinfect food packaging to keep the contents. The water can seep into seams and closures. Even canned goods with dents or rust should go, as the integrity of the can is compromised. When in doubt, the trash is the safest choice.
- Open food packages and leftovers
- Cardboard boxes and paper wrappers
- Cans with dents, rust, or swelling
- Glass jars with damaged or loose lids
- Food stored in cloth or mesh bags
- Anything you cannot clean completely
What Can Be Saved
Only sealed, undamaged cans and glass jars that did not touch sewer water can be kept. Check each item carefully. Wipe the outside with a bleach solution or a food-safe disinfectant. Let them air dry completely before putting them back on the shelf.
If the sewer leak was in a nearby room and the pantry items never got wet, they are likely fine. But inspect everything for signs of moisture or odor. Any item with a questionable seal or that smells odd should be discarded. Your nose and eyes are not perfect, so be cautious.
Cleaning the Pantry
After removing all contaminated food, clean the pantry thoroughly. Wear gloves, a mask, and eye protection. Remove all shelves and wash them with warm water and dish soap, then disinfect with a bleach solution. Let everything dry completely before restocking.
Pay attention to cracks, corners, and under shelves where water can hide. Use a flashlight to check for any residue. If the floor or walls are warped or stained, you may need professional help. Water damage can lead to mold, which is another health risk.

When to Call the Pros
If the sewer leak soaked into the pantry walls, floor, or subfloor, you may need professional help. The pros have equipment to extract water and dry out structures. They can also assess for mold growth, which can spread quickly in humid conditions.
In Quincy, the humid coastal climate means moisture can linger and cause problems. If you notice a musty smell or see discoloration, act fast. Local water damage pros can help with structural drying and dehumidification. They can also advise on what to keep and what to discard after a sewer leak.

Can I save canned food if I wash the cans?
Only if the cans are undamaged and did not directly touch sewer water. If they were in the same room but stayed dry, you can wipe them with disinfectant. If they got wet, even slightly, throw them out because the seal may be compromised.
What about food in plastic containers with lids?
Plastic containers are not safe if the sewer water reached them. The water can get into the threads or under the lid. Unless the container is completely sealed and dry, discard the food inside. Wash the container thoroughly if you want to reuse it.
How do I know if the pantry is safe to use again?
After cleaning and drying, check for any lingering odor or stains. If the surfaces feel dry and look clean, it is likely safe. But if you are unsure, call a professional to inspect for hidden moisture or mold. Your health is worth the extra step.
