Yes — and here’s why it matters more than you think.
It only takes a few seconds, but rinsing your cans before opening them can help protect your health. While most of us open a tin without a second thought, the outside of that can may carry more than just your next meal.
Cans go through a long journey before reaching your kitchen:
Warehouses
Delivery trucks
Store shelves
Maybe even storage in your own pantry
👉 Along the way, they can pick up dust, grime, rust, or bacteria — all of which can cling to the lid.
When you open a can, the blade or opener cuts through the lid, and some of the liquid inside can splash upward or pull residue from the surface into the food.
That means whatever was on the lid might end up inside your meal.
This matters especially for:
Canned fish (like tuna or sardines)
Canned beans or corn
Fruit packed in syrup
All of which are often eaten without further cooking.
It’s simple. Just:
Rinse the top of the can with water
Add a bit of dish soap or white vinegar if you like
Dry if needed, then open
That’s it — a small habit for better hygiene.
A 10-second rinse = less bacteria + safer food.
Make it part of your routine — especially when feeding kids, elderly people, or anyone with a sensitive stomach
