What Do I Do With Pet Food Exposed to Flood Water?
Last updated October 31, 2026
The short answer
Why Flood Water Ruins Pet Food
Flood water is not clean. It can contain sewage, chemicals, and debris. Even if the water looks clear, it may carry germs that can make your pet sick. Dry kibble soaks up moisture, and wet food can grow mold quickly.
Unopened bags are not safe either. Cardboard and paper packaging soak through, and even plastic bags can have tiny tears. Cans can rust or leak, and the seals may fail. The safest choice is to throw everything out that came into contact with flood water.
How to Dispose of Contaminated Food
Put the food in a sealed trash bag before throwing it away. This keeps other animals from getting into it. If you have compost, do not add it there, as flood water can leave harmful residues that survive composting.
Clean the area where the food was stored. Wash shelves, cabinets, or floors with soap and water, then wipe with a disinfectant. If you live in Fresno, the hot, dry climate can help dry out surfaces, but still clean thoroughly first.
- Seal food in a plastic bag before disposal
- Wipe down storage areas with disinfectant
- Rinse any cans that may have been touched
- Check for water stains on nearby surfaces
- Wash your hands after handling anything flood-affected
Cleaning Pet Bowls and Feeding Areas
Wash food and water bowls in hot, soapy water, then rinse. If the bowls are dishwasher-safe, run a cycle with a sanitizing setting. For plastic bowls, you may want to replace them, as scratches can trap bacteria.
Scrub the floor or mat where bowls sit. Use a disinfectant that is safe for pets, and let the area dry completely. If the feeding area is near a wall, check for water damage behind it, as moisture can hide there.
When to See a Vet
If your pet ate any flood-exposed food, watch for signs of illness. Vomiting, diarrhea, lethargy, or loss of appetite can be red flags. Contact your vet right away if you notice any of these symptoms.
Do not wait to see if symptoms pass. Flood water can carry bacteria like E. Coli or salmonella, which can cause serious illness. Your vet can advise on the next steps and may suggest bringing your pet in for a check.
Preventing Future Exposure
Store pet food in airtight, waterproof containers. This helps protect it from future flooding and from pests. Keep food off the floor, on a shelf or table, to reduce the chance of water contact.
If you live in an area prone to flooding, keep a small emergency supply of pet food in a sealed bin. Knowing where it is can help you grab it quickly if you need to leave. Also, check your home for leak points, like doors or windows, where water could enter.
- Use plastic or metal bins with tight lids
- Store food at least a few inches off the floor
- Keep a list of your pet's usual food brand
- Check your home's entry points for gaps
- Have a plan for moving pets and supplies

Can I save unopened canned pet food after a flood?
It is right to throw it away. Flood water can seep into the can's seam or cause rust. Even if the can looks intact, the heat and moisture can compromise the food inside. Your pet's health is more important than saving a few cans.
What should I do with pet food that was in a sealed plastic container?
If the container was fully sealed and kept dry, the food may be safe. Check the container for cracks or water marks. If any water got inside, discard the food. Clean the container with hot, soapy water and disinfect it before using it again.
How do I clean a pet food bowl after flood water touched it?
Wash the bowl in hot, soapy water, then rinse. If it is dishwasher-safe, run it through a cycle. For plastic bowls, consider replacing them, as scratches can harbor bacteria. Dry the bowl completely before using it again.
