Rats in the Pantry: What Food to Throw Away

You open the pantry and find chewed packets, droppings and a musty smell. The immediate question is what is still safe to eat. Rats contaminate far more food than they eat, with urine, droppings and hair, so caution is the sensible rule.

This guide gives practical advice on what to discard and what you can save. When in doubt, throw it out.

The short answer

Throw away any food that rats have gnawed, any open or loosely packaged food they could have reached, anything with droppings, urine stains or hair, and any food in damaged packaging. Items in intact, sealed metal cans, glass jars or thick sealed containers can usually be saved after the outside is cleaned and disinfected. Do not try to pick out droppings or cut away gnawed areas. Contamination can spread through the food even if it is not visible. Clean the pantry thoroughly before restocking.

Throw away

1. Anything gnawed or chewed.
2. Open packets, bags and boxes, including cereals, flour, rice, pulses, snacks, biscuits and spices.
3. Food in paper, cardboard, cloth and thin plastic packaging, even if it looks intact.
4. Any food with droppings, urine stains, hair or a strange smell.
5. Bread, fruit and vegetables that have been exposed.
6. Pet food that has been contaminated.

Usually safe after cleaning

• Sealed metal cans, after washing and disinfecting the outside and discarding if dented or damaged.
• Sealed glass jars with intact lids, after cleaning the outside.
• Sealed, thick containers that were clearly closed and show no sign of entry.

Be cautious with any container whose lid is not airtight.

Why not save partly eaten food

• Rats leave urine and droppings throughout, which you cannot see or remove.
• Cooking may not remove all risks and toxins.
• Illness from contaminated food is not worth the saving.

Cleaning the pantry

1. Wear gloves and a mask. Ventilate.
2. Remove all food and discard what is contaminated.
3. Remove droppings and nests with the wet method. Do not sweep.
4. Wipe all shelves, walls and floors with disinfectant, then wash and dry.
5. Wash containers and utensils.
6. Check for entry points and seal them.

Restocking

• Use sealed metal, glass or thick plastic containers.
• Keep food off the floor.
• Do not store food in cardboard or paper.
• Monitor for new signs.

If someone has eaten contaminated food

Watch for symptoms such as stomach upset, fever or other illness, and see a doctor if concerned.

When to call a professional

If rats keep returning to the pantry, call a pest control professional to find the entry points and treat the infestation.

Frequently asked questions

Can I wash rice or dal that rats touched?

We advise discarding it, since contamination can be spread throughout.

What about sealed packets?

If the packet is intact and clean outside, it may be safe, but be cautious with paper-based or thin packaging.

Is cooking enough to make food safe?

It may not remove all contaminants. Do not rely on it.

How do I prevent a repeat?

Seal gaps and store food in rodent-proof containers.
